JWELL Small Diameter PE / PPR / PE-RT / PA Single and Twin Pipe High-Speed Extrusion Lines

From our workshop to your production floor – JWELL delivers with proven performance.

1. Who We Are – and Why You Should Care

We are JWELL, one of China’s most established and trusted plastics extrusion machinery manufacturers. For over 25 years, we have designed, built, and delivered thousands of extrusion lines to pipe producers in Europe, the Americas, Southeast Asia, and the Middle East. Our name stands for reliability, innovation, and real throughput – not on paper, but in your factory.

Today, we present our Small Diameter PE / PPR / PE-RT / PA Single and Twin Pipe High-Speed Extrusion Lines – a system continually refined through countless customer feedback loops, field trials, and ongoing R&D. This is not a generic machine; it is a production tool built specifically for Φ16 mm to Φ75 mm pipe sizes, equally capable of processing PE, PPR, PE-RT, and PA.

We don’t sell you a pile of components. We deliver a complete production solution, backed by our global service network, spare parts warehouses, and a team of engineers who can communicate with you – in language and in technology.

2. Key Parameters at a Glance – Full Range Specifications

We offer three standardised line models for different diameters and materials. The table below gives you a complete comparison for quick evaluation:

Our commitment to you: The output figures shown are stable 8-hour continuous averages using standard PE/PPR pipe-grade materials – not momentary peaks. We welcome you to verify them on site during factory acceptance with your own raw materials.

3. Your Configuration Path – Our Selection Logic

The table above lists all possible combinations, but you don’t have to figure it out alone. We use a proven selection process to get you the right fit in one step:

Step 1 – What material are you running?

PE (Polyethylene) – water supply, gas, conduit pipes – high output, wide processing window.

PPR (Random Copolymer Polypropylene) – hot/cold water plumbing – requires higher torque, so output is roughly 15–20% lower than PE for the same specification (as shown above).

PE-RT (Polyethylene of Raised Temperature Resistance) – underfloor heating, hot water pipes – processing characteristics close to PE; refer to PE/PERT models.

PA (Polyamide/Nylon) – automotive ducts, pneumatic tubes – requires drying and a wear-resistant screw; we offer custom screw designs.

We adjust screw geometry, barrel heating zones, and downstream cooling methods according to your material – at no extra charge for standard adjustments.

Step 2 – What pipe diameter do you produce?

For Φ20 ~ Φ75 mm (medium to larger small diameters) → choose the PE/PERT 75 or PPR 75 line.

For dedicated Φ16 ~ Φ32 mm small diameters (e.g., underfloor heating, capillary tubes) → choose the PE/PERT 32 line – you get higher linear speeds with the same extruder.

Step 3 – What output capacity do you need?

The three rows under each model in the table correspond to different capacity tiers:

Special note: The PE/PERT 32 is purpose-built for small-diameter high-speed production – even with a 90 kW motor, it reaches 350–400 kg/h, offering exceptional cost-performance.

4. What This Line Does – in Plain Words

Our extrusion line is an integrated system that converts polymer pellets into precision small-diameter pipes at consistently above-average production speeds. The standard scope includes:

Our in-house high-torque single-screw extruder (JWS-H 60/40 or JWS 65/33 from the table) with our proprietary barrier-type screw.

Vacuum sizing tank with digital pressure regulation.

Multi-zone spray cooling tank – stainless steel, corrosion-resistant.

Servo-driven haul-off with closed-loop tension control.

In-line flying cutter or fully automatic winder (you choose).

Siemens/PLC-based control panel with intuitive touchscreen.

The result: stable, round, uniform-wall-thickness pipes, shift after shift, with minimal scrap and high uptime. We have witnessed our lines running over 800 continuous hours without any quality fluctuation – our customers’ production logs confirm it.

5. Our Technical Advantages – What Sets Us Apart

5.1 High Speed Without Compromising Quality

Our barrier-screw design, combined with optimised barrel cooling, delivers up to 25% higher linear speed than conventional extruders of the same power – without raising melt temperature, so dimensional stability remains intact even at full speed.

5.2 Four Materials, One Machine – Flexible Changeovers

Switching from PE to PPR, or PE-RT to PA, takes no more than 60 minutes – including purging and temperature stabilisation. This is enabled by:

Quick-access screw and barrel design for easy cleaning.

Pre-stored material recipes in the PLC.

Standardised connections for tooling and sizing sleeves.

This flexibility lets you respond to market fluctuations without buying a second line.

5.3 Built for 24/7 Production – Not 9-to-5

Our gearboxes have 30% extra margin over industry standards.

Screws are bimetallic or nitrided to HRC 65–68 hardness.

Cooling tanks are fully welded 304 stainless steel – not painted carbon steel.

Designed for three-shift continuous operation in tropical, dusty, or high-humidity environments – because that’s where our customers are.

5.4 Intelligent Control – Everything at Your Fingertips

Our PLC system records every production parameter: melt pressure, temperature, line speed, wall thickness, and outer diameter. Data can be exported for quality traceability or connected to your MES. We also offer a remote diagnostic interface – with your permission, we can help troubleshoot before you even notice an issue.

6. What Our Global Customers Say – We Listen Carefully

We don’t guess your needs; we learn from you. Here are the five top reasons that consistently drive customers to choose JWELL:

6.1 Consistent Quality, Shift After Shift

“We measure outer diameter every hour – tolerance never exceeds ±0.1 mm, even when ambient temperature swings 15°C.” – Plant manager, Germany.

6.2 Lower Electricity Bills

Our 90 kW configuration consumes 0.22–0.25 kWh per kg of PE – among the lowest in independent tests, and we’re happy to verify it on site with your material.

6.3 Fast Material Changeovers

Producers in the Middle East and Southeast Asia appreciate running PE in the morning and switching to PPR in the afternoon without losing a full shift.

6.4 Real After-Sales Support – Not Just a Phone Number

We maintain spare parts warehouses in Europe, the USA, the UAE, and Thailand. Emergency shipments from stock are dispatched in under 24 hours. We send our own engineers for site commissioning – never subcontract.

6.5 Full Compliance with International Standards

Our lines produce pipes meeting ISO 4427, ISO 15874, ASTM F876, EN 12201, and CSA B137. If you require specific third-party certification (e.g., TÜV, BV), we coordinate during factory acceptance.

7. Frequently Asked Questions – Straight from Our Sales Engineers

Q1: Do you send engineers for installation?

Yes. We offer three levels:

Remote guidance – senior engineers guide you via video.

On-site service – 15–20 days of on-site commissioning (travel and accommodation at buyer’s cost).

Turnkey – we handle civil works, utilities, and operator training.

Q2: Can I run regrind?

Absolutely. Our screw handles up to 30% industrial regrind (factory scrap) without affecting output. For post-consumer regrind, we recommend a degassing screw – discuss your needs with our team.

Q3: What’s the difference between JWS-H 60/40 and JWS 65/33, and how do I choose?

JWS-H 60/40 is our high-torque, high-speed series with 90 or 110 kW motors – for maximum capacity. JWS 65/33 is our classic economical model with a 75 kW motor – for entry-level or medium output. Simply put: it’s about output vs. budget – we have the right solution either way.

Q4: If I choose 75 kW now and need more later, can I upgrade?

Yes. Our frame and gearbox are designed with future upgrades in mind – you can later replace the motor and screw components. However, we recommend sizing for your next 3-5 years’ demand upfront to avoid duplicate investment.

8. Quick Selection Matrix – One Chart to Decide

9. Why JWELL – More Than Just Machinery

We are not traders. We are engineers and machinists – all major components are designed, cast, machined, and assembled in our own factories. This gives us full control over quality, delivery, and cost.

We have delivered over 600 small-diameter extrusion lines to more than 70 countries. Our customer base includes some of the largest pipe groups in Turkey, India, Vietnam, and Brazil – and we can share names under NDA.

Moreover, we invest 5% of annual revenue in R&D – not in marketing. Our latest screw and cooling generations come directly from customer pain points, not from white papers written in isolation.
