Plastic Profile Extrusion Line for Multi-Material Applications

A modular extrusion platform tailored to your polymer—TPU, PP, PE, PVC, or ABS. Specialized in Co-extrusion (Dual-color / Soft-Hard) and precision sizing routes to match your most complex profile designs.

  • Multi-Material Customization: We engineer the screw and torque profile specifically for your resin, from high-elastic TPU to high-shrinkage PP.
  • Co-Extrusion: Dual-color, soft-hard, and cap-layer structures via integrated co-extruder module (product-dependent).
  • Sizing Strategy: Free-sizing direct-to-water cooling for contact-sensitive surfaces, or vacuum calibration for hollow and complex cross-sections.
  • Modular Downstream: Custom-shaped haul-off pads and material-specific cutting (Saw / Rotary / Guillotine), with optional straightening correction.
  • Turnkey Reliability: Genuine drive and control components (Siemens, ABB, OMRON) selected by suitability, not by cost-cutting.

Configuring Your Single Screw Profile Extrusion Line

Jinxin configures each plastic profile extrusion line from your drawing, material grade, and acceptance criteria — not from a standard catalog. Our engineering workflow aligns screw design, die tooling, and downstream modules to your profile geometry, surface target, and shape stability needs. PVC is supported as pelletized compound only.

Why Manufacturers & Procurement Leaders Choose Jinxin

Factory-Accepted Before Shipping

We don’t just check mechanical movement—we run full-load production trials before shipment.

  • Dimensional Verification: We run the line to prove the die delivers your exact profile dimensions and tolerances. For surface-critical profiles, we verify finish quality and absence of defects under production conditions.
  • The “Start-Up Recipe”: We record the successful processing parameters (temperatures, speeds, haul-off tension) used during the trial. You receive this Data Sheet to skip the guesswork and start production immediately.
  • Material Calibration: Using a custom compound or unfamiliar grade? We recommend shipping your raw material to us for testing. We calibrate the machine to your reality, ensuring precision from start.

Transparent, Line-by-Line Quoting

Your quotation isn’t a vague summary. It is a line-by-line manifest listing every equipment component and brand (e.g., Siemens, ABB), ensuring the hardware matches the promise.

  • Detailed Configuration List: Every motor, inverter, tank, and controller is listed by brand and model.
  • Clear Service Options: On-site installation and training are quoted as a distinct, transparent line item—no surprise fees later.

Trusted by Manufacturers Serving Global Brands

  • We produce transparent PVC track profiles for sliding power socket systems — a wall-mounted rail that allows socket modules to slide freely along the track.

    The profile must be optically clear for a premium home-interior look and dimensionally precise for the socket module to glide smoothly without jamming.

    Jinxin’s screw design gave us a stable, bubble-free melt from the start. The transparency and snap-fit precision passed our client’s incoming inspection on the first submitted batch.

  • Our main product is ABS wall protection profiles for hospital corridors — the guard rails mounted along walls to prevent damage from beds and wheelchairs.

    Surface consistency and color uniformity across long production runs are critical, because these profiles are installed in visible, high-traffic areas.

    Jinxin configured the die and cooling path to hold tight dimensional tolerances over continuous runs. We have been running the line for over two years with stable output.”

Custom Plastic Profile Extrusion Line FAQ by Material (PVC / PP / PE / TPU / ABS)

Select your material below to see common profile extrusion questions and configuration guidance.

PVC FAQ (Pelletized Compound Only)

If the profile geometry and stability allow, free-sizing direct-to-water cooling can reduce tooling contact, which helps when surface appearance is the priority. Vacuum calibration is typically selected when the cross-section requires stronger shape lock (often for hollow/complex profiles).


Final selection depends on the drawing, PVC compound formulation, and the agreed appearance/defect criteria.

An optional film-laminating (protective wrapping) unit can be added at the end of the line to apply surface protection before handling, stacking, and packing.

The film type and application method are configured to your profile shape and surface requirement.

Delamination in soft-rigid PVC co-extrusion is typically caused by poor interfacial bonding between the two PVC compounds.

We manage this through material compatibility review (confirming whether a tie-layer or compatibilizer is needed), temperature strategy to support bonding at the interface, clean material handling to avoid contamination, and flow balance through the co-extrusion tooling to maintain consistent layer ratios.

Final settings depend on your specific compound pair and layer structure, and are verified against your acceptance method.

PP & PE FAQ

PP and PE have high crystallization rates and significant post-mold shrinkage. Dimensional control starts at the die — we compensate for die swell in the tooling design.

After the die, we use extended multi-stage vacuum tanks and high-volume water spray to freeze the dimensions rapidly, reducing temperature gradients across thick and thin walls.

Haul-off type and contact pressure are selected to maintain steady pull without imprinting. For complex cross-sections, we add in-line straightening units to counteract post-cooling deformation.

Yes. PP and PE are semi-crystalline and continue to shrink as they cool, unlike amorphous resins (ABS, PVC) which stabilize faster.

This means PP/PE lines typically need longer cooling paths, more aggressive water spray coverage, and lower haul-off contact pressure to avoid surface marking on the softer material.

We configure these parameters based on your specific resin grade and profile geometry.

TPU FAQ

TPU is sensitive to friction and moisture. We use specialized non-stick coatings on our sizing sleeves and a screw design that ensures gentle homogenization to prevent air entrapment and surface defects.

Dimensional stability depends on cooling consistency and traction control matched to your profile geometry.

We configure the cooling path and water temperature to avoid uneven contraction, then tune haul-off tension to maintain steady pull without deforming the profile.

Verification is done against your drawing tolerances using agreed sampling points under production conditions.

Yes. For ultra-soft TPU, we configure the line with a specialized “soft-touch” caterpillar haul-off and chipless rotary cutters to prevent the profile from deforming during traction and cutting.

ABS FAQ

ABS surface quality depends on melt homogeneity and precise temperature control.

Our ABS-specific screw geometry is designed to deliver a uniform melt with minimal flow lines.

We also recommend integrated desiccant dryers to eliminate moisture before processing — residual moisture in ABS causes “silver streaks” (splay marks) that ruin surface gloss.

ABS contains a butadiene rubber phase that gives it impact resistance. Excessive shear or barrel temperature can degrade this rubber phase, making the final profile brittle.

Our screw geometry is designed with a lower compression ratio and controlled shear to preserve the polymer’s molecular structure.

We also monitor melt temperature closely to keep it within the safe processing window — high enough for good flow, low enough to avoid thermal degradation.
