Why Pipe Fittings Belong With the Extrusion Line
A plastic pipe is only useful when it can be joined, branched and terminated, and that is exactly what pipe fittings do. Elbows, tees, couplings, reducers, end caps, unions and valves turn a bare length of pipe into a functioning water supply, drainage, gas or cable-protection network. For any pipe manufacturer, producing the pipe and the matching fittings in one coordinated factory is not a luxury. It is the most direct way to control quality, synchronize inventory, protect margin and respond quickly to project orders that almost always specify both pipe and fittings together.
Faygo, Wanplas 공장 with 22 years of dedicated experience in plastic pipe and profile extrusion, designs its production philosophy around this complete-factory idea. The company operates three specialized factories, with its FAYGOPLAST pipe and profile operation covering 26,650 square meters in Zhangjiagang City, only two hours from Shanghai Airport. Rather than treating the injection molding of fittings as a separate, outsourced step, Faygo integrates a dedicated pipe-fitting injection molding machine with its PVC, HDPE and PP-R pipe extrusion assembly lines so the two processes share the same raw-material supply, quality system, engineering team and shipment schedule.

The strategic benefit is also commercial. When a distributor buys pipe from you and fittings from a different source, the fitting supplier captures the higher-margin, lower-volume accessory business and can even undercut your pipe price by bundling. Owning the fitting process keeps that margin inside your plant and lets you offer project packages that competitors who only extrude pipe cannot match. Wanplas, as the parent brand, encourages every specialized factory to think in terms of the full value chain rather than a single machine category.
How a Pipe-Fitting Injection Molding Machine Works
At its core, an injection molding machine plasticizes a thermoplastic resin in a heated barrel, then injects the melt into a steel mold where it cools and solidifies into the shape of a fitting. The machine has two main assemblies: the injection unit and the clamping unit. The injection unit contains the screw and barrel; the clamping unit holds the mold, closes it under force, and opens it to eject the finished part.
The plasticizing process begins when resin pellets, typically PP-R, PVC or HDPE compounded with the required additives, drop from the hopper into the feed zone of the barrel. The screw rotates and conveys the material forward. In the compression zone the flight depth decreases, raising pressure and shear so the solid pellets melt and compact. In the metering zone the melt reaches a uniform temperature and pressure, ready to be injected. A non-return valve at the screw tip prevents backflow during the injection stroke.
During injection, the screw moves forward like a plunger and pushes the molten plastic through the nozzle, sprue, runner and gate into the mold cavity. The clamping unit must hold the mold shut against the melt pressure; if the clamping force is too low, the parting line flashes and the fitting develops a thin fin that must be trimmed. After the cavity fills, a holding pressure phase compensates for shrinkage as the melt cools, and then the screw retracts and rotates to prepare the next shot while the part cools in the mold.
For pipe fittings, the mold is the heart of the system. A fitting mold is a multi-cavity steel tool, often with a hot runner, that defines the internal and external geometry of an elbow or tee with tight tolerances on the socket diameter and the sealing ring groove. Because fittings have complex internal undercuts and threads, the mold usually includes unscrewing mechanisms, collapsible cores or side actions. Faygo supplies the injection machine as the platform and coordinates the mold design so the two are optimized together, which is the only reliable way to hit a stable cycle time on a branching fitting.
Compared with a general-purpose injection machine, a pipe-fitting machine is tuned for relatively thick-walled, pressure-rated parts made from a narrow family of materials. The screw design favors gentle, uniform plasticizing of heat-sensitive compounds such as PVC, and the clamping system is sized for the high projected area of large-diameter fittings rather than for thin cosmetic housings. The result is a machine that looks similar to a standard press on the outside but is engineered for one demanding job on the inside.
The barrel temperature profile, screw speed, back pressure and mold temperature controller settings are all part of the process recipe. For PP-R, melt temperatures around 230 to 260 degrees Celsius are common, while PVC requires a much cooler, shear-controlled profile to avoid degradation. A stable, repeatable recipe is what allows a fitting produced at the start of a shift to match one produced eight hours later, which is essential when the fitting must thread or solvent-weld onto a pipe made on a different machine in the same plant.
Clamping Force by Fitting Size
The single most important number when sizing a fitting machine is the required clamping force, measured in kilonewtons. The clamping force must exceed the product of the cavity pressure and the total projected area of the parting line, with a safety margin for viscoelastic relaxation and machine wear. Under-sizing causes flash; over-sizing wastes energy and floor space and makes the mold harder to handle.
The table below maps common fitting sizes to the clamping force typically required and to the machine class that Faygo recommends. Projected area grows roughly with the square of the fitting diameter, so the clamping force climbs steeply from DN20 to DN110. These are planning values for standard wall fittings in PP-R or HDPE; PVC pressure fittings, glass-fiber reinforced compounds and multi-cavity tools will shift the requirement upward.
| Fitting Size (DN) | Typical Projected Area per Cavity (cm²) | Required Clamping Force per Cavity (kN) | Suggested Machine Class | Common Cavity Count |
|---|---|---|---|---|
| DN20 | 18 to 28 | 180 to 280 | 1,200 kN servo-hydraulic toggle | 8 to 16 |
| DN25 | 28 to 40 | 280 to 400 | 1,200 to 2,200 kN | 8 to 12 |
| DN32 | 40 to 60 | 400 to 600 | 2,200 kN | 4~8 |
| DN40 | 60 to 95 | 600 to 950 | 2,200 to 3,500 kN | 4 to 6 |
| DN50 | 95 to 150 | 950 to 1,500 | 3,500kN 기준 | 2 to 4 |
| DN63 | 150 to 230 | 1,500 to 2,300 | 3,500 to 5,000 kN | 2 to 4 |
| DN75 | 230 to 340 | 2,300 to 3,400 | 5,000 kN | 1~2 |
| DN90 | 340 to 490 | 3,400 to 4,900 | 5,000 kN and above | 1~2 |
| DN110 | 490 ~ 700 | 4,900 to 7,000 | 5,000 to 7,000 kN class | 1~2 |
표에서 보듯이 DN20 커플링은 높은 캐비티와 적당한 클램프 기계에서 높은 부품 당 생산량을 달성하기 위해 이상적이며, DN110 엘보드는 예상 면적이 너무 크기 때문에 부품 당 생산량을 높이기 위해 1~2개의 캐비티를 갖춘 무거운 프레스로 실행해야 합니다. 동공 설계의 미덕은 요구량과 동등한 속도로 재료를 소비하기 위해 캐비티 수를 조정하는 것입니다.
One practical rule many plants violate is buying a single giant press for everything. A 7,000 kN machine running DN20 fittings wastes energy, ties up capital and produces far more flash and stress than necessary. A balanced plant uses two or three machine classes in parallel, each dedicated to a diameter band, exactly as the extrusion line is split into small, medium and large pipe dies.
Faygo 파이프 피팅 주입 시리즈
Faygo supplies a dedicated pipe-fitting injection molding machine series built around the diameter bands described above. The series uses a servo-hydraulic toggle clamping system for the mid-range and a servo-hydraulic direct-clamp architecture for the heavy class, both driven by a closed-loop servo pump that delivers oil only when the machine demands it. The following specification table lists the standard configuration by clamping-force class.
| Clamping Force Class (kN) | Screw Diameter (mm) | Shot Weight, PP (g) | Plasticizing Capacity (g/s) | Platen Size (mm) | Mold Height Range (mm) | Typical Fitting DN |
|---|---|---|---|---|---|---|
| 1,200 | 40 | 170 | 28 | 420 × 420 | 150 to 420 | DN20 to DN32 |
| 2,200 | 50 | 380 | 45 | 540 × 540 | 200 to 550 | DN32 to DN50 |
| 3,500 | 60 | 720 | 70 | 680 × 680 | 250 to 680 | DN50 to DN90 |
| 5,000 | 70 | 1,250 | 100 | 820 × 820 | 300 to 800 | DN90에서 DN110까지의 범위입니다. |
Every machine in the series is equipped with a plasticizing unit tuned for pipe-grade compounds. The barrel and screw use a corrosion- and wear-resistant nitride or bimetallic package suitable for calcium-carbonated PP-R and for PVC stabilizers. The injection unit supports both cold-runner and hot-runner molds, and the control system stores recipes by fitting type so an operator can switch from a DN25 tee to a DN32 elbow with a single recipe call rather than manual re-tuning.
클램핑 유닛은 소형 클래스에서는 빠른 속도와 에너지 절약, 긴 기계 수명을 제공하는 5점 토글을 사용하며, 대형 클래스에서는 플레이트 크기와 강도가 중요한 만큼 직접 유압식 클램프나 2플레이트 클램프를 사용합니다. 타이 바 간격은 넉넉하여 넓은 다공구 형식이 변형 없이 맞출 수 있으며, 이젝터 패턴은 표준 핀과 유압 코어풀을 모두 지원합니다.
From a buyer’s perspective the value of the series is not a single headline number but the consistency across the family. Because the control platform, hydraulic philosophy and barrel geometry are shared, an engineer who learns the 1,200 kN machine can run the 5,000 kN machine with minimal retraining, and spare parts such as seals, sensors and servo drives are largely common. That commonality lowers the inventory and training cost of running a multi-press fitting cell.

Matching Extrusion Lines
The injection machine is only half of the complete-pipe-factory equation. The other half is the pipe extrusion assembly line, and Faygo offers a range of real, field-proven lines that pair naturally with the fitting press. Two of the most relevant for fitting-matched production are the PP-R/PE-RT 파이프 압출 라인 and the PVC double 파이프 압출 라인.
The PP-R/PE-RT 파이프 압출 라인 produces PP-R and PE pipes from 16 mm to 160 mm and PE-RT pipes from 16 mm to 32 mm, covering the same small-to-medium diameters where the bulk of injection-molded fittings are consumed. A plant running this line for PP-R hot-and-cold water pipe can run a 1,200 to 3,500 kN fitting press in the same hall to make the matching elbows, tees and couplings, so a single order for a plumbing system is fulfilled from one quality system.
| 1. 재료 시스템: 유연한 PVC 재킷 합성물 | PP-R/PE-RT 파이프 압출 라인 |
|---|---|
| Applicable materials | PP-R, PE, PE-RT |
| 파이프 직경 범위 | 16 mm to 160 mm (PP-R / PE); 16 mm to 32 mm (PE-RT) |
| 벽 두께 capability | Up to 6.5 mm on the core equipment series |
| Matched fitting machine class | 1,200 kN to 5,000 kN by pipe DN |
| Typical application | Hot and cold water supply, floor heating, potable water |
| 제어 시스템 | Intelligent control with freely set parameters and real-time adjustment |
The PVC double 파이프 압출 라인 produces two pipes in parallel from 16 mm to 40 mm (and up to 63 mm depending on configuration), which is the workhorse for residential cold-water and conduit systems. Because it makes two pipes at once, the matched fitting press for DN16 to DN40 fittings should be sized so its hourly consumption of PVC compound tracks the twin-pipe output, avoiding a fitting shortage that forces the extruder to slow down.
| 1. 재료 시스템: 유연한 PVC 재킷 합성물 | PVC 이중 파이프 압출 라인 |
|---|---|
| Applicable material | PVC (UPVC) |
| 파이프 직경 범위 | 16 mm to 40 mm twin-out; configurable to 63 mm |
| Output characteristic | Two pipes extruded simultaneously from one die head |
| Matched fitting machine class | 1,200 kN to 2,200 kN for small DN fittings |
| Typical application | Residential cold water, electrical conduit, drainage branch |
| Process note | Lower melt temperature and controlled shear to protect PVC stability |
Both lines are CE and ISO certified and benefit from the same intelligent control philosophy as the fitting press, so the operator environment is consistent plant-wide. For large-diameter municipal work, Faygo’s HDPE pipe capability extends the same logic upward: a heavy DN110 fitting press pairs with a large HDPE pipe line to serve gas and water mains, though the fitting sizes then push toward the 5,000 kN and above class.
The key takeaway is that Faygo does not sell the injection machine as an island. It sells a matched pair: a pipe line whose diameter range overlaps the fitting machine’s clamping band, so the two consume the same compound, share the same color masterbatch and meet the same pressure-rating specification.
Production Cell Layout
A balanced pipe-and-fitting plant is more than two machines placed near each other. It is a flow: raw material arrives, is blended and dried, feeds both the extrusion line and the injection machine, becomes pipe and fittings, is inspected, and moves to warehousing and shipment. The table below outlines a representative single-cell layout and the floor area each zone typically requires, using Medium capacity as the planning assumption.
| 생산 구역 | Main Equipment | Typical Floor Area (m²) | 기능 |
|---|---|---|---|
| Material preparation | High-speed mixer, dryer, central feeding system | 40 to 70 | Blending resin, masterbatch and additives; drying hygroscopic grades |
| Pipe extrusion | PP-R or PVC extrusion assembly line with haul-off and cutter | 120 to 200 | Producing pipe in the target diameter range |
| Fitting injection | 1 to 3 pipe-fitting injection machines with molds | 90에서 180까지 | Producing elbows, tees, couplings and caps |
| Mold and maintenance | Tooling rack, temperature controllers, spare zone | 25 to 50 | Mold change, tuning and preventive maintenance |
| Quality and finishing | Inspection bench, trimming, printing | 30 to 60 | Dimensional check, marking, deflash |
| Warehouse | Pallet racking for pipe and fittings | 150 to 400 | Buffer stock and finished-goods dispatch |
For a Medium-capacity single cell, the total covered area often lands between 450 and 960 square meters, leaving room for forklift aisles and future expansion. The injection zone is deliberately placed adjacent to the pipe cutting and inspection zone so a quality engineer can compare a fitting socket with the pipe end on the same bench, catching tolerance drift before it becomes a customer complaint.
Material preparation deserves special attention. Running the extruder and the injection machine from one blended-material stream is what guarantees color and grade consistency. If the extrusion line uses a 2 percent white masterbatch and the injection machine uses a 3 percent batch from a different lot, the fitting will visibly mismatch the pipe. A shared high-speed mixer and loss-in-weight feeder eliminate that risk.

Cycle Time, Weight and Output
Output from a fitting cell is governed by three linked variables: the shot weight of the fitting, the cycle time of the injection machine, and the number of cavities in the mold. Understanding this relationship lets a plant predict how many fittings per hour a given press will deliver and whether that rate matches the pipe line’s appetite for fittings.
| Fitting Type | Single Part Weight (g, PP-R) | Cycle Time (s) | Cavities | Parts per Hour | kg per Hour |
|---|---|---|---|---|---|
| DN20 coupling | 9 | 14 | 16 | 4,110 | 37 |
| DN25 elbow | 18 | 18 | 12 | 2,400 | 43 |
| DN32 tee | 38 | 24 | 8 | 1,200 | 46 |
| DN50 elbow | 95 | 32 | 4 | 450 | 43 |
| DN90 elbow | 420 | 55 | 2 | 131 | 55 |
| DN110 tee | 900 | 70 | 1 | 51 | 46 |
Two patterns stand out. First, smaller fittings win on parts-per-hour through high cavity counts, while larger fittings win on mass-per-hour through heavier shots, even at low cavity counts. Second, the mass throughput of a well-balanced cell stays in a surprisingly narrow band, which is exactly what you want when the goal is to feed a pipe line whose own output is also relatively steady by diameter.
주기 시간은 비효율성의 대부분이 숨겨진 곳입니다. 18초 만에 실행할 수 있는 부품이 실제로는 26초 만에 실행되므로 몰드 냉각이 부적절하면 생산량이 30% 감소합니다. 핫런너 몰드, 적절한 냉각 회로 및 올바르게 크기가 조정된 몰드 온도 컨트롤러는 전체 용량을 숨겨진 상태로 유지하면서도 더 큰 프레스를 구입하지 않고도 회복시키는 레버입니다.
표는 또한 플랜트가 왜 여러 기계 클래스를 필요로 하는지 설명합니다. 5,000kN의 프레스에서 DN20 커플링을 사용하면 각 부품당 속도가 катастроrophically 느려집니다. 그 이유는 큰 플래튼과 클램프 스트로크가 작은 공구에 낭비되기 때문입니다. 1,200kN의 프레스는 DN110 티를 물리적으로 잡을 수 없습니다. 기계 클래스를 피팅 직경에 맞추는 것이 전체 셀이 이론적인 출력을 유지하는 유일한 방법입니다.
서보 드라이브, 핫 러너 및 테이크아웃 로봇
현대적이고 경제적인 피팅 셀을 정의하는 세 가지 기술은 서보 유압 드라이브, 핫 러너 및 테이크아웃 로봇입니다. 각각은 비용 센터를 공격하며, 함께하면 수익성 있는 피팅 운영과 손익이 미미한 운영을 구분합니다.
The servo-hydraulic drive replaces a fixed-speed motor and proportional valve with a servo motor and pump that rotate only when the machine needs flow. During cooling, when a conventional hydraulic machine idles its motor and bleeds energy as heat, a servo machine drops to near-zero power draw. For a fitting plant running many cycles per day, the energy saving versus a conventional hydraulic machine is substantial and quickly repays the modest price premium. This is a technology comparison, not a brand claim: the benchmark is the older fixed-pump hydraulic architecture, which remains common in entry-level imported units.
핫 러너는 금형 내부의 플라스틱 용융을 온도로 유지하여 차가운 스프루 또는 러너가 형성되지 않도록 합니다. 차가운 러너 장착 금형에서는 각 샷마다 러너 트리를 재분쇄하고 재처리해야 하며, 재분쇄된 재료는 여러 번 재사용할 경우 성능이 저하됩니다. 핫 러너는 이러한 폐기물을 완전히 제거하여 주기를 단축하고, 안정적인 온도로 용융이 각 동굴에 들어감으로써 일관성을 개선합니다. 재분쇄가 문제가 되는 색상 또는 PVC 피팅의 경우 핫 러너는 필수적에 가깝습니다.
테이크아웃 로봇 또는 테이크아웃 조작기는 완성된 피팅을 금형에서 제거하고 컨베이어에 놓거나 상자에 넣습니다. 수동 추출은 느리고 일관성이 없으며 움직이는 플래튼 근처에서는 위험합니다. 측면 진입 또는 상단 진입 암이 있는 로봇은 동일한 동작을 매 사이클마다 수행하여 안정적인 자동 데플래쉬와 하위 작업에 대한 신뢰할 수 있는 처리 기능을 제공합니다. 압출 라인과 일치하는 셀에서는 한 작업자가 두 세 개의 프레스를 감독할 수 있으므로 소규모 팀이 전체 피팅 부서를 운영할 수 있습니다.
이 세 가지 기술은 피팅 중심의 공장에 선택 가능한 사치품이 아닙니다. 생산량 증가에 따라 피팅 당 비용이 감소하는 셀과 비용이 계속 고수준으로 유지되는 셀의 차이입니다.
Material and Mold Considerations
Pipe fittings are made from the same base polymers as the pipe they join, but the processing window is tighter because the part is thick, load-bearing and often pressure-rated. The three dominant materials are PP-R for hot and cold water, PVC (including UPVC) for cold water, drainage and conduit, and HDPE for gas, water mains and outdoor systems.
PP-R is semi-crystalline and tolerates a wide processing window, but its shrinkage of roughly 1.5 to 2.0 percent must be designed into the mold so the socket dimension lands on the pipe after cooling. It is also mildly hygroscopic, so a dehumidifying dryer is advisable before plasticizing to avoid silver streaks. PP-R fittings are usually joined by heat fusion, which demands a clean, oxide-free socket surface, so the mold finish and demolding behavior matter for joint quality.
PVC는 열에 민감하여 폴리올레핀과 같이 가공할 수 없습니다. 용융을 생성하려면 높은 열 대신 적절한 배럴 온도에서 제어된 전단 작용이 필요하며, 그렇지 않으면 변성되고 스크류와 배럴을 공격하는 산이 방출됩니다. PVC 용접 금형에는 광택이 나고 부식에 강하고 빠른 냉각 프로필이 있는 동굴이 필요합니다. PVC 용접 부품은 종종 용제 용접을 하기 때문에 소켓의 치수 정확도와 플래시가 없는 것이 누출이 없는 결합을 보장합니다.
HDPE fittings for gas and water are typically large, thick and slow-cooling, which pushes them toward the heavy machine class and long cycle times. Their environmental stress-crack resistance depends on avoiding excessive shear heating and contamination, so the plasticizing unit must be gentle and the material stream clean. HDPE fittings are usually butt-fused or electrofusion, and the molded geometry must hold the fusion parameter window steady.
Mold design is where material meets geometry. A fitting mold must manage undercuts for threads and sealing grooves, often with unscrewing mechanisms or collapsible cores, and it must cool the thick sections fast enough to hit the target cycle. A poor mold will force the injection machine to wait, breaking the balance with the extrusion line. Faygo coordinates mold specification with the injection series so the tool and the press are validated as one system rather than blamed separately when output falls short.
색상과 첨가제 일관성도 여기에서 보입니다. 파이프와 피팅 모두 동일한 마스터 배치 농도와 레트다운 비율을 사용해야 하며 배럴 체류 시간을 제어하여 열에 민감한 색상이 생산 런트의 처음과 마지막 샷 사이에서 변하지 않도록 해야 합니다. 이러한 이유로 레이아웃 섹션에서 공유되는 재료 준비 구역이 비용을 절감하는 이유입니다.
응용 산업
파이프 및 피팅 공장은 유동체를 이동하는 모든 산업, 케이블을 보호하는 산업 및 플라스틱으로 건축하는 산업을 대상으로 합니다. 최종 제품은 구체적이고 쉽게 시각화할 수 있어 피팅 셀이 얼마나 다양한 자산인지 알 수 있습니다.
건물 물 공급 분야에서, 맞춤형 사출 성형된 엘보, 티, 커플링 및 유니언을 갖춘 PP-R 및 PE 파이프는 가정과 사무실의 숨겨진 골격을 형성하며 식용 찬물과 뜨거운 물을 운반합니다. 바닥 난방 시스템에서는 동일한 제품군에 속하는 PE-RT 파이프를 사용합니다. 배수 및 하수 분야에서는 PVC 파이프와 용제 용접식 부품이 조용하고 내구성 있게 폐수 운반을 담당합니다.
도시 공학에서는 수도관 및 가스 배급을 위해 대구경 HDPE 파이프와 부품이 사용되며, 단 한 개의 누출되는 조인트는 공공 사건으로 간주되므로 부품 품질 기준이 매우 높습니다. 농업 관개는 특별한 도구 없이 파이프에 끼워지는 압축식 부품으로 성형된 PE 드립 및 스프링클러 파이프에 의존하며, 농부들은 긴 파이프를 신속하게 조립할 수 있습니다.
통신 및 전력 분야에서는 섬유, 전력 및 신호 라인을 안전하게 지하로 연결하기 위해 일치하는 굽힘과 결합부를 갖춘 PVC 및 PE 케이블 보호 파이프를 사용합니다. 이러한 산업들에서 부품은 부속품이 아니라 시스템을 설치, 재배치 및 수리할 수 있는지를 결정하는 구성 요소입니다. 파이프와 부품 모두를 제어하는 공장은 전체 설비의 무결성을 관리합니다.
Wanplas는 이러한 광범위를 중국 플라스틱 기계로 글로벌 고객을 따뜻하게 하는 사명으로 삼고 있으며, 따라서 Faygo와 같은 단일 전문 공장은 고객이 하나의 통합 생산 기반에서 건설, 도시, 농업 및 산업 시장을 대상으로 서비스를 제공할 수 있도록 합니다.
선택 가이드
압출 라인과 피팅 기계의 적절한 조합을 선택하려면 고객의 목표 제품과 생산량에 따라 선택해야 합니다. 아래 표는 일반적인 요구 사항을 Faygo 구성으로 변환하여 설명합니다.
| Customer Requirement | Recommended Pipe Line | Recommended Fitting Machine | Planning Note |
|---|---|---|---|
| Residential PP-R plumbing, DN20 to DN63 | PP-R/PE-RT 파이프 압출 라인 (16~160mm) | 1,200 to 3,500 kN pipe-fitting series | Size fitting press by the largest DN in the range |
| PVC conduit and cold-water, DN16 to DN40 | PVC double 파이프 압출 라인 (twin-out) | 1,200 to 2,200 kN class | Match fitting output to twin-pipe throughput |
| PE-RT floor heating, DN16 to DN32 | PP-R/PE-RT 파이프 압출 라인 (PE-RT 16 ~ 32mm) | 1,200 kN high-cavity class | Favor cavity count for small parts |
| HDPE municipal pipe, DN90에서 DN110까지의 범위입니다. | Large HDPE pipe capability | 5,000 kN and above class | Plan for long cycles and low cavity counts |
| Full plumbing package, DN20 to DN110 | PP-R line plus PVC line | 1,200, 3,500 and 5,000 kN classes | Run three presses in parallel by diameter band |
The guide makes the central point again: select the fitting machine by the largest fitting diameter you intend to produce, then add smaller presses for the high-volume small sizes. A customer who only makes DN20 to DN32 fittings should never buy a 5,000 kN press, just as a customer making DN110 tees cannot make do with a 1,200 kN press.
Volume matters as much as diameter. If a plumbing package sells mostly DN20 and DN25 parts, a single high-cavity 1,200 kN machine may cover 80 percent of fitting demand, with a larger press reserved for the occasional DN63 and DN90 item. This right-sizes capital and keeps utilization high.
Faygo’s engineering team runs this selection exercise during the quotation stage, using the customer’s bill of materials and expected order mix to simulate cavity counts and machine loading before any equipment is built. The output is a balanced cell specification rather than a list of unrelated machines.
Technology Comparison
Within the fitting-machine category there are three dominant drive architectures, and the right choice depends on duty cycle, energy cost and part value. The comparison below is technology versus technology, benchmarking against conventional fixed-pump hydraulics and entry-level imported units rather than naming any supplier.
| 기준 | Conventional Hydraulic | Servo-Hydraulic (Faygo series) | All-Electric |
|---|---|---|---|
| Energy use at idle | 높은 수준 | Very Low | Lowest |
| Energy use under cycle | 중간에서 높은 수준까지 | 중간 | 저전압 |
| Repeatability | 좋음 | Very Good | Excellent |
| Initial cost level | 저전압 | 중간 | High to Premium |
| Maintenance complexity | 중간 | 중간 | 저전압 |
| Best fit | Low-volume, price-driven | High-volume fitting cells | Ultra-clean, precision |
For a fitting plant matched to a pipe line, where machines run long shifts at high cycle counts, the servo-hydraulic architecture is usually the sweet spot. It captures most of the energy saving of all-electric presses at a Medium rather than Premium cost, and it tolerates the dusty, utility-grade environment of a pipe factory better than the finely sealed all-electric drive.
The conventional hydraulic machine still has a place for very low-volume or budget-constrained startups, but its idle energy draw and weaker repeatability make it a poor match for a cell that must hold socket tolerances hour after hour next to an extrusion line. The entry-level imported unit often wins on headline price yet loses on spare-parts lead time and local support, which is a hidden cost when a press stops during a project deadline.
Faygo’s standard recommendation for a new fitting cell is therefore servo-hydraulic across the 1,200 to 5,000 kN range, reserving all-electric only for customers with clean-room-grade requirements or extreme precision needs that justify the Premium cost level.
서비스 및 지원
Buying a matched pipe-and-fitting plant is a long-term commitment, and Faygo backs it with the shared Wanplas group service philosophy. The support begins before shipment and continues through the life of the equipment.
Every machine undergoes a 72시간 연속 작동 test before delivery, so the customer receives equipment that has already run, not equipment that is hoped to run. For a fitting cell paired with an extrusion line, the two are validated together where practical, confirming that pipe and fitting emerge from the same quality envelope.
On arrival, Faygo provides installation and commissioning by engineers who set the machines, align the molds, tune the process recipes and train the customer’s operators. Training covers daily operation, mold change, basic fault diagnosis and preventive maintenance so the plant can run independently after handover.
예비 부품 정책은 Wanplas의 표준인 매년 500달러의 무료 예비 부품과 보증 기간 내에 손상된 부품에 대한 보증 교체를 제공합니다. 피팅 시리즈는 클램핑 클래스별로 공통 부품을 공유하므로 고객의 예비 부품 재고는 작고 프레스가 보증 기간 내에 예비 부품이 부족하여 작동을 중단할 위험은 낮습니다.
Remote support is available through the control system’s data link, letting a Faygo engineer review process data and guide correction without a long travel delay. For major issues, on-site service is arranged. The open-factory policy also welcomes customers to visit Zhangjiagang, inspect the 26,650 square meter FAYGOPLAST operation, and audit the 13 national patents and CE and ISO certified manufacturing process before and after purchase.
Beyond the machines themselves, Wanplas offers factory consulting that includes water and electricity design, three-dimensional workshop layout, worker configuration and training, and even turnkey construction of a new plant from zero. For an existing plant, the old-machine-replacement path is designed for zero-downtime upgrade, and the capacity-expansion path targets bottleneck optimization that can double output without rebuilding the hall.
FAQ
Why should a pipe manufacturer also make fittings instead of buying them?
Producing fittings in-house keeps the higher-margin accessory business inside your plant, guarantees that the fitting material, color and pressure rating match the pipe, and lets you quote complete plumbing or drainage packages. It also removes the lead-time and quality risk of depending on a separate fitting supplier whose tolerances may not line up with your pipe.
특정 피팅의 클램핑 힘을 어떻게 계산합니까?
Multiply the cavity pressure, typically 300 to 500 bar for fittings, by the total projected area of the parting line including runners, then add a safety margin of roughly 10 to 20 percent. The result in kilonewtons tells you the minimum machine class. Our table in section 3 gives planning values from DN20 to DN110 so you can size the press before quoting.
Can one injection machine make all fitting sizes from DN20 to DN110?
Not efficiently. A DN110 tee has a projected area dozens of times larger than a DN20 coupling, so it needs a 5,000 kN or larger press, while the small coupling runs best in a high-cavity 1,200 kN machine. A balanced plant uses two or three machine classes in parallel, each dedicated to a diameter band, exactly as the extrusion line splits dies by size.
Is a hot runner worth the extra mold cost for pipe fittings?
For most fittings, yes. A hot runner eliminates the cold sprue and runner scrap, shortens cycle time by removing runner cooling, and improves consistency, which matters for colored and PVC fittings where regrind is problematic. The higher mold cost is usually recovered quickly through material savings and higher output in a high-volume cell.
What is the energy saving of a servo-hydraulic fitting machine?
Compared with a conventional fixed-pump hydraulic machine, a servo-hydraulic drive cuts idle power draw to near zero and reduces under-cycle energy use substantially, because the servo pump delivers oil only when the machine demands it. The exact saving depends on duty cycle and local energy cost, but for a multi-shift fitting cell the payback on the modest price premium is typically fast.
파이프와 피팅 색상을 일관되게 유지하려면 어떻게 해야 합니까?
압출 라인과 사출기를 하나의 혼합 재료 흐름에서 실행하고 동일한 마스터 배치 농도와 레트다운 비율을 모두 사용하며 배럴 체류 시간을 제어하여 첫 번째 샷과 마지막 샷 사이에서 색상이 변하지 않도록 합니다.
피팅으로 가장 잘 성형되는 재료는 무엇입니까?
PVC is the most demanding because it is heat-sensitive and degrades if processed with too much heat instead of controlled shear. It needs a corrosion-resistant barrel and screw, a polished mold, fast even cooling and tight process control. HDPE is easier to plasticize but slow to cool in thick sections, which is why large HDPE fittings need the heavy machine class and patient cycle times.
Faygo는 라인이 설치된 후 어떤 지원을 제공합니까?
