Engineering Capabilities & Die Tooling
Plasticpartsmfg manages the entire extrusion chain under rigorous quality control: from wire-EDM extrusion die fabrication and sizing calibrator design to dual-durometer co-extrusion and post-cut fabrication.
Custom Extrusion Die Tooling
Precision EDM-cut dies, vacuum sizing calibrators, and cooling tanks tuned to specific resin shrinkage and flow dynamics to prevent warpage and wall thickness variance.
- • In-house DFM review before steel cutting
- • Hardened tool steel for wear resistance
- • Die trial sample submission with CMM reports
Dual & Multi-Material Co-Extrusion
Seamlessly unite rigid structural backings with flexible sealing lips, multi-color indicators, or UV-resistant cap layers in a single, un-delaminated continuous profile.
- • Rigid PVC + Flexible PVC combinations
- • Polypropylene (PP) + Santoprene / TPE seals
- • Acrylic / PC clear caps with matte diffusers
Downstream In-Line Operations
Eliminate manual post-processing costs. Our extrusion lines integrate precision automated cutting, online rotary punching, adhesive tape lamination, and batch markings.
- • Automatic high-speed guillotine & saw cutting
- • In-line pressure-sensitive adhesive (PSA) taping
- • Consecutive part numbering & laser coding

Material selection directly governs extrusion melt flow, surface finish, UV resistance, and profile rigidity. We process both utility resins and high-performance engineering thermoplastics:
| Resin Grade | Key Mechanical Characteristics | Standard Applications | Linear Tolerance Band |
|---|---|---|---|
| Rigid PVC (uPVC) | High stiffness, flame retardant (UL94 V-0), chemical resistance | Cable conduits, window trims, electrical raceways | ±0.12 mm |
| HDPE / LDPE | Impact strength, low friction coefficient, moisture barrier | Fluid transport tubing, guide rails, conveyor strips | ±0.18 mm |
| Polycarbonate (PC) | Optical clarity, high heat resistance, shatter resistance | LED diffusers, light fixtures, sight glasses | ±0.10 mm |
| ABS | Dimensional stability, cosmetic finish, impact resilience | Appliance trims, structural profiles, internal brackets | ±0.15 mm |
| Flexible PVC / TPE / TPU | Elastomeric recovery, variable shore hardness (55A–90A) | Gaskets, edge protectors, automotive door seals | ±0.25 mm |
Need customized compounds? We supply UV stabilizers for outdoor installations, anti-static grades for electronics manufacturing, custom Pantone/RAL color matching, and food-compliant or REACH-verified plastic materials upon engineering request.
