Custom Plastic Extrusion Services
Plasticpartsmfg provides dedicated contract manufacturing for custom plastic profiles. Based in Shenzhen, China, we support product development teams, mechanical engineers, and procurement managers requiring consistent, high-volume plastic components for industrial, construction, and consumer applications.
We handle the full production lifecycle, from initial design review and die manufacturing to continuous extrusion runs and secondary finishing, ensuring your parts meet strict dimensions and functional material properties.
Precision tooling and in-line dimensional control for repeatable cross-sections.
Manufacturing Specifications
Our facility handles a wide range of plastic formulations and complex cross-sectional geometries, maintaining tight tolerances and uniform wall thicknesses throughout long continuous runs.
Engineering and Material Selection
Effective extrusion relies on proper resin chemistry and precise die tuning. We match materials to your application's operating temperature, chemical exposure, Shore hardness, and UV durability requirements.
Rigid PVC & ABS
Engineered for rigid structural profiles, cable trays, and framing where stiffness, high impact strength, and dimensional stability are paramount under continuous loads.
Flexible PVC, TPE & TPU
Formulated for dynamic seals, gaskets, bumper strips, and trim requiring flexible recovery, vibration dampening, and resilience across variable operating temperatures.
Polyethylene & Polypropylene
PE and PP offer superior resistance to acids, moisture, and aggressive solvents. Excellent choice for fluid conduit, outdoor protective strips, and low-friction wear surfaces.
Multi-Material Co-Extrusion & Custom Colors
Need a rigid mounting spine fused directly with a flexible sealing lip? Our tooling supports dual-durometer co-extrusion and custom RAL/Pantone color matching directly in the melt stream.
Secondary Operations & Finishing
Raw profiles frequently demand downstream fabrication to integrate seamlessly with assembly lines. We integrate in-line and secondary post-extrusion workflows to shorten your delivery cycles.
High-speed in-line guillotine, saw, or optical rotary cut-to-length systems yielding tight length tolerances and clean burr-free ends.
Post-extrusion stamping, slot punching, CNC milling, and precision drilling for snap fits, fasteners, and fluid drainage apertures.
Automated pre-application of acrylic foam tapes, heat-activated adhesives, or magnetic strips with protective peel liners for swift field install.
Batch packaging configured for warehouse staging, including protective sleeving, coiled spools, carton barcoding, and export wooden crating.
When to Choose Plastic Extrusion
Extrusion represents the most cost-effective manufacturing process for parts requiring continuous lengths and uniform cross-sections. Tooling dies cost a fraction of injection molds and scale rapidly to high linear meter outputs.
Transitioning long components from CNC routing or continuous 3D printing to profile extrusion drastically slashes per-meter part costs and stabilizes cycle times.
