A PE silicone core cable protection pipe high speed extruder is the production system that manufactures the smooth, low-friction HDPE duct used to protect and route communication optical cables that are buried directly in the ground. Faygo, a Wanplas factory with 22 years of dedicated experience in plastic pipe and profile extrusion lines, builds these high speed co-extrusion lines for manufacturers who supply telecom operators, highway authorities, railway operators and municipal utilities. This guide explains what a silicon core duct is, how the double-layer co-extrusion system works, what a complete production line contains, which process parameters matter, how to select the right machine configuration, how to inspect the finished pipe, and how to troubleshoot the most common defects. Whether you are planning a new facility, replacing aging equipment, or expanding capacity, the information below gives you a concrete technical foundation for specifying a high speed extrusion line that produces reliable communication optical cable protection pipe.
The demand for buried optical cable duct keeps rising because fiber-to-the-home, 5G mobile backhaul, data center interconnection and smart-grid communication all depend on protected, easily upgradeable cabling routes. Conventional smooth HDPE duct can only be installed by pulling, which is slow, damages the cable jacket, and limits the length of a single installation section. The silicone core pipe solves this by placing a permanent solid silicone lubricant layer on the inner wall during extrusion, so the cable is installed by air-blowing over distances of 1000 to 2000 meters in a single operation. Producing that inner layer consistently at high line speed is exactly what a well-designed high speed extruder must deliver, and that is the focus of this article.
What Is a PE Silicone Core Cable Protection Pipe
A PE silicone core cable protection pipe, also called a silicon core duct or HDPE silicon core duct, is a high-density polyethylene conduit with a co-extruded solid silicone lubricant layer permanently bonded to its inner surface. The base tube is made from pipe-grade HDPE, while the inner layer is a thin film of silicone compound, typically 0.05 to 0.15 millimeters thick, that is extruded together with the base layer in a single pass through a multi-channel die head. The result is a single-wall duct that combines the mechanical strength and weatherability of HDPE with the permanent low friction of silicone.
The defining performance metric is the inner-wall dynamic friction coefficient. A normal HDPE pipe has a dynamic friction coefficient of about 0.35 to 0.45 against a cable jacket, which is too high for long air-blown installation. A qualified silicon core duct reduces this to 0.08 or lower. At that friction level, a compressor can blow a lightweight optical cable through the pre-laid duct at several meters per second, placing 1000 to 2000 meters of cable in one continuous operation without pulling ropes, grease, or intermediate manholes. This installation method is known as air-blown cable installation, and it is the main reason telecom operators specify silicon core duct for new networks.
The duct is produced in fixed nominal sizes expressed as outer diameter over inner diameter. The most common communication specifications are phi32/26, phi40/33, phi46/40 and phi50/41, where the first number is the outer diameter and the second is the inner diameter in millimeters. Color identification stripes, usually three or four longitudinal stripes, are co-extruded on the outer wall so that different cable routes can be distinguished inside a shared trench. The table below maps the standard specifications to wall thickness, the maximum cable outer diameter that can be installed, and the typical coil length used for transport and deployment.
Standard Specification and Coil Length Reference
| Specification (OD/ID, mm) | Nominal Wall Thickness (mm) | Max. Installed Cable OD (mm) | Standard Coil Length (m) | Typical Color Stripes |
|---|---|---|---|---|
| phi32/26 | 3.0 | 24 | 1000 / 1500 / 2000 | 3 |
| phi40/33 | 3.5 | 30 | 1000 / 1500 | 3 or 4 |
| phi46/40 | 3.0 | 36 | 1000 | 3 or 4 |
| phi50/41 | 4.5 | 38 | 1000 | 4 |
The wall thickness is determined by the difference between the outer and inner diameters divided by two, and it must stay within tolerance because both ring stiffness and the available cable clearance depend on it. The HDPE base provides the structural performance, while the thin silicone layer does none of the load bearing yet delivers almost all of the installation advantage. Because the silicone layer is so thin, holding its thickness and continuity across the full length of a high speed run is the central manufacturing challenge addressed later in this article.
Why Silicone Core Duct Outperforms Conventional Single-Layer Duct
Silicon core duct changes the economics of underground communication cabling because it moves the friction problem from the installation crew to the factory. A conventional single-layer HDPE duct relies on the base polymer surface, which is relatively rough and has a high friction coefficient. Cable placement therefore requires pulling grips, rope, and often periodic application of liquid lubricant, with short achievable lengths and a real risk of jacket damage. The silicon core duct replaces all of that with a factory-applied permanent lubricant surface.
The comparison below is a technology-to-technology comparison, not a brand comparison. It contrasts the silicon core co-extruded duct with the conventional single-layer duct that older lines still produce. This distinction matters when you evaluate whether to invest in a dedicated high speed silicon core extrusion line rather than adapting a standard pipe line.
| Аспект | PE Silicon Core Duct | Conventional Single-Layer Duct |
|---|---|---|
| Inner wall friction coefficient | 0.08 or lower (dynamic) | 0.35 to 0.45 |
| Cable installation method | Air-blown, 1000 to 2000 m per blow | Pulling, short sections |
| Lubrication | Permanent solid silicone layer | Periodic liquid lubricant |
| Installation speed | High, continuous | Low, step by step |
| Cable jacket damage risk | Low | Higher under pull load |
| Network upgrade convenience | Re-blow new cable anytime | Re-pull, more labor |
| Required line technology | Multi-layer co-extrusion die head | Single-layer standard die |
For the operator, the practical benefit is lower total installed cost per meter of fiber route, faster project completion, and the ability to add capacity later simply by blowing in another cable. For the pipe manufacturer, however, the benefit comes with a manufacturing obligation: the silicone layer must be continuous, uniform and well bonded, and it must survive coiling, transport, trench laying and decades in the ground. That obligation drives every design decision in the extrusion line.
The Double-Layer Co-Extrusion System
Серцевина екструдера з силіконовою трубою – це двошарова, або точніше, багатоповерхнева, система коекструзії. Зовнішня і основна структура HDPE виробляється первинним екструдером, а тонкий шар силікону подається спеціальним невеликим коекструдером в одну і ту ж головку прес-форми, щоб два матеріали злилися на площині прес-форми і виходили як одна єдина труба. Третій, ще менший екструдер може додавати кольорові позначки на зовнішній поверхні. Всі три потоки пластичного матеріалу зливаються в триканальній головці коекструзії, яка є серцем технології.
The primary extruder is a single-screw machine, most often sized at 65 millimeters in diameter with a 33-to-1 length-to-diameter ratio, or scaled up to 75 millimeters diameter and 33 L/D for higher output. The screw uses a barrier design combined with a mixing head so that the HDPE melts uniformly, degasses, and builds stable pressure. Output from this machine typically ranges from 250 to 450 kilograms per hour depending on screw size and screw speed. A barrier screw with a dispersive mixing section is important because silicone masterbatch and color masterbatch are added at low percentages and must be distributed without streaks.
Екструдер для силіконового сердечника значно менший, зазвичай 30 міліметрів в діаметрі з 25 L/D, або 35 міліметрів в діаметрі з 25 L/D на лініях високої швидкості. Він пластифікує силіконову суміш при контрольованій температурі і подає точний, невеликий обсяг розплаву в внутрішній канал голови преса. Тому що шар силікону тонкий лише 0,05-0,15 міліметра, точна точність дозування цього маленького екструдера безпосередньо контролює якість продукту. Екструдер для нанесення кольорових позначок ще менший, зазвичай 20-25 міліметрів в діаметрі, і він наносить кольорові позначки ідентифікації на зовнішню стінку.
The three-channel die head is where the technology is won or lost. Its flow channels must keep the HDPE and silicone melts at their correct, separate temperatures until the very last moment, then join them so the silicone forms a uniform, concentric inner skin with strong interfacial bonding. Two engineering targets dominate die design. First, silicone layer uniformity: the layer thickness must stay within a tight band along the entire pipe length and around the circumference, otherwise local friction rises and air-blown performance becomes inconsistent. Second, interfacial bonding: the peel strength between the silicone layer and the HDPE base must be high enough that the layer never delaminates during coiling, bending, or installation, yet the two materials must not inter-diffuse into a mushy boundary.
Faygo supplies this co-extrusion system as part of its high speed PE silicon core лінія екструзії труб, built on the same pipe extrusion platform that covers 12 to 575 millimeter diameters for water, gas, drainage and communication applications. The Faygo line uses internationally recognized brand electrical components and an intelligent control system that lets the operator set and adjust parameters in real time. The table below presents two Faygo configuration tiers for communication silicon core duct, drawn from the standard machine sizes used for this product family.
Die head temperature control deserves special attention because the HDPE and silicone melts have different thermal windows and must not be allowed to mix too early. The head is typically heated in independent zones so the operator can hold the HDPE channels near 200 to 215 Celsius while keeping the silicone channel in its narrower 180 to 200 Celsius band. Melt pressure at the die is monitored so that fluctuations, which would otherwise translate into wall thickness variation, are caught immediately. A well-built three-channel head also makes the silicone layer adjustable independently of the base wall, which is the feature that lets one line serve both thin phi32/26 duct and thicker phi50/41 duct without changing the fundamental low-friction performance.

The downstream auxiliary equipment deserves its own specification view because it determines whether the high speed potential of the extruder is actually realized on the floor. The vacuum calibration box, spray cooling tanks, caterpillar haul-off, ink-jet printer with meter counter, dual-station chip-free cutter and automatic coiling winder must all keep pace with the die output. The table below lists the auxiliary unit parameters that Faygo configures to match the two main line tiers.

Complete Лінія виробництва Конфігурація Chain
A complete high speed silicon core лінія екструзії труб is a sequence of synchronized units, each responsible for one stage of converting HDPE pellets, silicone masterbatch and color masterbatch into coiled finished duct. Understanding the chain helps you plan the factory layout, utility supply and operator workflow. The chain runs as follows.
Centralized feeding delivers the HDPE base material, silicone masterbatch and color masterbatch to the correct extruder hoppers. Gravimetric or volumetric dosing keeps the low-percentage silicone and color additions accurate, which is essential for layer uniformity. The primary and secondary extruders then plasticize their respective melts. The three-channel co-extrusion die head and its tooling, consisting of the die and the core rod, set the final pipe geometry. The gap between the die and the core rod, together with the draw-down ratio, controls wall thickness and concentricity. After the die, the molten pipe enters the vacuum calibration box.
The vacuum calibration box fixes the outer diameter by drawing the soft pipe against a cooled calibration sleeve under vacuum. The vacuum level is held at minus 0.02 to minus 0.06 megapascal, and the cooling water is kept at 15 to 20 Celsius so the surface sets quickly without thermal shock. From calibration the pipe passes through a multi-stage spray cooling water tank where the wall is fully solidified. The caterpillar haul-off then pulls the pipe at a controlled, steady speed. Because the haul-off speed sets the draw-down, it is the master variable that couples extruder output to final dimensions.
After cooling, an ink-jet printer applies identification and a meter counter records length. The dual-station chip-free cutter cuts the pipe at the programmed coil length without generating debris that could contaminate the duct. Finally, an automatic coiling winder winds the pipe onto reels of 1000 to 2500 millimeters diameter, depending on the pipe size and the transport coil length selected. The synchronization of extruder output, haul-off speed and cutter timing is managed by the line control system so that wall thickness, length and coil weight stay consistent across the whole production run.
From a layout perspective, the standard configuration occupies about 36 meters of floor length and the high speed configuration about 42 meters, plus space for material storage, coil handling and finished-goods staging. Faygo’s factory consulting service can provide water and electricity design, three-dimensional workshop layout, worker configuration and training as part of a turnkey project, which is especially useful for a new facility built from zero.
Process Parameters and Settings
Stable, repeatable process parameters are what separate a high speed line that produces qualified silicon core duct from one that produces scrap. The parameters span material selection, barrel temperature profile, die head temperature, silicone temperature, vacuum, cooling water temperature, haul-off speed and draw-down ratio. The table below consolidates the working window for communication silicon core pipe.
Process Parameter Window
| Stage / Parameter | Range / Setting | Notes |
|---|---|---|
| HDPE grade | PE80 / PE100 pipe material | MFR 0.2 to 0.6 g/10 min at 190 Celsius, 5 kg; density 0.945 to 0.955 |
| Barrel zone 1 temperature | 170 to 185 Celsius | Feed and compression |
| Barrel zone 2 temperature | 185 to 195 Celsius | Melting |
| Barrel zone 3 temperature | 195 to 205 Celsius | Mixing |
| Barrel zone 4 temperature | 200 to 210 Celsius | Metering |
| Die head temperature | 200 to 215 Celsius | Uniform across head |
| Silicone material temperature | 180 to 200 Celsius | Stable for thin layer |
| Calibration vacuum | minus 0.02 to minus 0.06 MPa | Sets outer diameter |
| Calibration water temperature | 15 to 20 Celsius | Fast surface set |
| Haul-off speed | 15 to 40 m/min, high speed 45 | Matches throughput |
| Draw-down ratio (DDR) | 1.2 to 1.6 | Controls wall thickness |
| Main screw speed | 20 to 60 rpm | Tune with haul-off |
Several parameter relationships deserve emphasis. The barrel temperature must increase gradually from feed to metering so that the HDPE melts without degradation; an overheated rear zone degrades the material while an underheated front zone causes melt fracture and a rough surface. The silicone melt must stay in its own narrow band so the thin layer forms smoothly; too cold and it streaks, too hot and it loses definition at the interface. The calibration vacuum and the haul-off speed together control outer diameter and wall thickness, so they are the first things to check when dimensions drift.
The draw-down ratio, defined as the ratio of the cross-sectional area of the die opening to the cross-sectional area of the finished pipe, normally sits between 1.2 and 1.6 for silicon core duct. A higher draw-down thins the wall and increases line speed but raises stress and can thin the silicone layer unevenly. A lower draw-down is gentler but limits output. The correct value is found by balancing the target wall thickness in the specification table against the available extruder output and the maximum safe haul-off speed.
How to Select the Right Faygo Line for Your Project
Selecting the right extrusion line starts from the pipe sizes you must supply and the daily output you must achieve. A manufacturer serving a regional telecom program with mostly phi32/26 and phi40/33 duct can run a standard speed line efficiently, while a supplier covering highway and railway programs with larger phi46/40 and phi50/41 duct, or one pursuing maximum throughput, should choose the high speed configuration. The recommendation table below maps common project requirements to the Faygo configuration that fits them.
Requirement to Конфігурація Recommendation
| Target Pipe OD | Daily Output Target | Coil Length Requirement | Recommended Faygo Конфігурація |
|---|---|---|---|
| phi32/26 | 8 to 12 km/day | 2000 m coils | Standard speed 65 mm line |
| phi40/33 | 10 to 15 km/day | 1500 m coils | Standard or high speed 65 mm line |
| phi46/40 | 12 to 18 km/day | 1000 m coils | High speed 75 mm line |
| phi50/41 | 12 to 20 km/day | 1000 m coils | High speed 75 mm line |
| Mixed sizes | Flexible | Mixed | High speed line with quick-change tooling |
Beyond diameter and output, consider utility capacity. The high speed line draws about 185 kilowatts of installed power and needs a stable cooling water supply at 15 to 20 Celsius, so the site must provide adequate electrical service and a chiller or cooling tower. Coil handling also matters: larger 2500 millimeter coils are heavier and need proper handling equipment at both the winder and the warehouse. If your program spans several diameters, invest in quick-change die and core-rod tooling so changeovers stay short and the line utilization remains high.
Faygo, as a Wanplas factory, can also draw on the broader Wanplas group capability for adjacent needs such as material handling, dosing and centralized control, supplied as part of a customized turnkey solution rather than as a separately named product. This keeps the project single-source and accountable while remaining within the Wanplas brand family.
Quality Inspection and Acceptance Tests
Silicon core duct is judged by a specific set of tests because its value depends on the inner wall as much as on the structure. The most important test is the inner-wall friction coefficient, measured on an air-blow simulation bench that reproduces the installation condition; a qualified duct shows a dynamic friction coefficient of 0.08 or lower. Ring stiffness confirms the duct can resist soil load, while the falling weight impact test verifies toughness at low temperature. Longitudinal reversion, measured at 110 Celsius for one hour, must not exceed 3 percent, confirming the pipe will not shrink excessively in service. The hydrostatic test confirms the wall integrity under pressure, and the silicone layer is checked for peel strength and scratch resistance so it stays bonded and intact.
Factory Inspection Items and Acceptance Criteria
| Test Item | Method / Reference | Acceptance Criterion |
|---|---|---|
| Inner wall friction coefficient | Air-blow simulation bench | Dynamic 0.08 or lower |
| Ring stiffness | Ring stiffness test | Per stiffness class |
| Falling weight impact | Falling weight impact test | No crack at low temperature |
| Longitudinal reversion | 110 Celsius, 1 hour | 3 percent or less |
| Гідростатичний тиск | Hydrostatic test | No failure at rated pressure and time |
| Silicone layer peel and adhesion | Peel test | No delamination |
| Scratch resistance | Scratch test | Silicone layer remains intact |
| Inner wall roughness Ra | Profilometer | Low, smooth surface |
| Wall thickness and eccentricity | Ultrasonic or cut section | Within specification tolerance |
| Outer diameter and ovality | Caliper or gauge | Within specification tolerance |
| Color stripe continuity | Visual and continuity check | Continuous, identifiable |
Ці тести повинні проводитися безперервно протягом виробничого циклу, а не лише в кінці, тому що дефекти, такі як смужки силікону або ексцентричність, з'являються періодично, коли параметр змінюється. Контроль якості Faygo включає 72-годинне безперервне тестування роботи перед відправкою, яке випробовує лінію в умовах виробництва і підтверджує, що вона може дотримуватися цих критеріїв протягом тривалого періоду, а не протягом кількох хороших хвилин.
Common Defects and Troubleshooting
Even a well-designed line produces defects when parameters drift, tooling wears, or material varies. The table below lists the defects most often seen in silicon core pipe production, their typical causes, and the corrective action. A disciplined operator uses this as a daily reference and treats any rise in air-blow resistance as a top-priority signal because it directly defeats the product’s purpose.
Defect, Cause and Remedy Reference
| Defect | Typical Cause | Corrective Action |
|---|---|---|
| Silicone layer discontinuous or streaked | Uneven silicone masterbatch feed, wrong melt temperature | Stabilize dosing, adjust silicone temperature to 180 to 200 Celsius |
| Inner wall bulge | Uneven cooling, poor concentricity | Check calibration vacuum, re-center die and core rod |
| Ексцентричність товщини стінки | Core rod misaligned, uneven heating | Realign die and core rod, balance barrel zones |
| Out-of-round ovality | Insufficient vacuum, haul-off speed mismatch | Raise vacuum, balance puller speed with output |
| Color stripe drift | Stripe extruder position offset | Adjust stripe co-extruder position and output |
| Coil spring-back and recoil | High residual stress, too-fast cooling | Slow cooling, use larger coil diameter |
| High air-blow resistance | Rough inner wall, non-uniform silicone | Check silicone layer, polish die land, verify Ra |
| Silicone delamination | Poor interface bonding | Increase interface temperature, optimize layer ratio |
| Surface roughness or shark skin | Melt fracture, temperature too low | Raise barrel and die temperature, adjust screw speed |
| Black spots or contamination | Material contamination or degradation | Filter melt, clean barrel, check screen changer |
| Outer diameter variation | Unstable haul-off, pressure fluctuation | Use closed-loop speed control, stabilize melt pressure |
| Poor stripe adhesion or fading | Wrong pigment, weak bonding | Use compatibilized masterbatch, verify temperature |
| Bubbles inside wall | Moisture, trapped gas | Dry material, use vented barrel zone |
| Low ring stiffness | Wall too thin, low grade material | Verify wall thickness, use PE100 pipe grade |
Більшість цих дефектів відносяться до трьох основних причин: нестабільне дозування низькопроцентних добавок, прес-форма або стержень сердечника, які не є концентричними, і калибрування або секція тяги, яка не синхронізована з екструдером. Рутінові роботи з перевірки точності дозування, узгодження прес-форми і стабільності вакууму кожного зміни дозволяють усунути більшість відходів, перш ніж вони починаються.
Приклади застосування and Deployment Scenarios
Communication optical cable protection pipe serves a broad set of deployment scenarios, all of which benefit from the air-blown installation that silicon core duct enables. Faygo’s лінія екструзії трубs are applied across water supply, drainage, gas, communication and agricultural irrigation, and the communication and power cable protection segment is a core application of its pipe product family. The concrete scenarios for silicon core duct are described below.
Long-haul trunk optical cable direct burial is the classic use. National and provincial backbone networks lay thousands of kilometers of duct each year, and the ability to blow a cable 1000 to 2000 meters in one operation sharply reduces manhole count and labor. City and municipal pipeline communication uses the same duct inside shared utility trenches, where color stripes separate telecom, power and other services. Highway and railway corridor communication runs duct along the roadbed or right-of-way so that the operator can later add capacity without excavating the pavement. Campus and park weak-current pipe networks use silicon core duct for building-to-building fiber, where frequent upgrades make air-blown installation especially valuable. Finally, 5G base station backhaul depends on protected fiber from the antenna site to the aggregation node, and silicon core duct offers the fast, low-risk routing that dense small-cell rollouts require.
For each scenario the pipe must survive decades underground, resist soil load and moisture, and protect the cable from mechanical disturbance during and after installation. The HDPE base delivers the weathering and chemical resistance, while the silicone core delivers the installation flexibility. A manufacturer serving these markets should therefore prioritize line consistency and the friction test above almost every other quality metric.
The deployment environment also shapes the specification choices a buyer should discuss with the equipment supplier. In long-haul and highway projects the duct is often laid in sandy or rocky backfill, so wall thickness and ring stiffness class must match the burial depth and traffic load, and the color stripes must stay visible after years of trench handling. In city and campus networks the duct shares trenches with power and water lines, which raises the importance of clean identification and of a smooth inner wall that supports repeated re-blowing as bandwidth demand grows. For 5G backhaul, rollout speed is often the deciding factor, and the air-blown method lets operators light a route quickly and add fibers later without new excavation. A producer who understands these differences can stock the right diameter mix, phi32/26 through phi50/41, and tune the line to switch between them with minimal downtime.
From the manufacturer’s side, serving multiple scenarios also means planning material logistics carefully. Pipe-grade PE80 and PE100 are supplied as natural or pre-colored pellets, and the silicone and stripe masterbatches are added at low percentages, so the dosing and storage system must keep each additive clean and dry. A small amount of contaminated or moist material can cause black spots, bubbles or streaks that fail the friction and appearance tests. Reasonable in-house practice includes separate silos or covered bins for each component, routine moisture checks on the base resin, and a documented changeover procedure when moving between pipe sizes or colors. These habits protect the investment in a high speed line by keeping its output saleable.

Часті запитання
What is a PE silicone core cable protection pipe?
Це трубка HDPE з покриттям твердим силіконовим змащувальним шаром на внутрішній стінці. Силіконовий шар знижує динамічний коефіцієнт тертя до приблизно 0,08, тому оптичні кабелі можна встановити за допомогою нагнітання повітря на великі відстані, а не тягнути їх.
Як працює установка кабелю, надуваного повітрям, з трубопроводом з силіконовим сердечником?
Компресор подає кабель через попередньо розміщений трубопровід, використовуючи постійно низькофрикційний шар силікону всередині. Одним натиском можна розмістити кабель на відстань 1000-2000 метрів без підтягування канатів або періодичного змащування, що швидше і м'якше для оболонки кабелю.
Який клас HDPE використовується для труб з силіконовим сердечником?
Матеріали класу PE80 або PE100 використовуються, з коефіцієнтом потоку розплаву 0,2-0,6 грамів на 10 хвилин при 190 градусах Цельсія під тиском 5 кілограмів, і густиною в діапазоні 0,945-0,955.
What production line speed can a high speed extruder reach?
Стандартна швидкість лінії становить 15-30 метрів на хвилину, а лінія високої швидкості, яка приводиться 75-міліметровим, 33 L/D одношнековим екструдером, досягає 45 метрів на хвилину, залежно від розміру труби і товщини стінки.
Скільки кольорових смуг потрібно, і що вони означають?
Більшість комунікаційних трубопроводів використовує три або чотири поздовжні кольорові смуги, коекструдовані на зовнішній стінці. Вони ідентифікують різні маршрути кабелю або операторів всередині спільної траншеї і повинні залишатися безперервними по всій катусі.
What is the typical draw-down ratio for silicon core pipe?
Коефіцієнт розтягування зазвичай знаходиться в діапазоні 1,2-1,6. Він встановлюється за допомогою отвору преса і швидкості тягових блоків і безпосередньо контролює товщину стінки, тому його необхідно балансувати з виходом екструдера і максимально допустимою швидкістю лінії.
How is product quality verified before shipment?
Faygo проводить 72-годинне безперервне тестування роботи перед відправкою, перевіряючи тертя, товщину стінок, крутизну, вплив і гідростатичні характеристики, а потім надає послуги з монтажу, налаштування та навчання операторів, щоб підтвердити, що лінія відповідає технічним специфікаціям проекту.

Висновок
A PE silicone core cable protection pipe high speed extruder is a specialized co-extrusion system built to manufacture the low-friction HDPE duct that makes air-blown optical cable installation practical. The technology rests on a three-channel die head that bonds a 0.05 to 0.15 millimeter silicone layer to the HDPE inner wall, a synchronized chain from centralized feeding through vacuum calibration, spray cooling, caterpillar haul-off, printing, chip-free cutting and automatic coiling, and a disciplined set of process parameters that hold the friction coefficient at 0.08 or lower. Faygo, a Wanplas factory with 22 years of pipe and profile extrusion experience, three specialized factories, 26,650 square meters of production space in Zhangjiagang, 13 national patents and CE and ISO certification, supplies these lines in standard speed and high speed configurations covering phi32/26 through phi50/41 duct.
If you are planning a new silicon core duct facility, expanding an existing line, or replacing aging equipment, the right next step is to share your target pipe sizes, daily output and coil length with our engineering team. We can configure a complete line to your specification, run sample duct on the floor for your verification, and support you from factory layout through commissioning and operator training. You are welcome to visit the factory, inspect the line, and trial the equipment with your own material before making a decision.
