Custom HDPE Extrusion Molding Services
Plasticpartsmfg provides custom HDPE (High-Density Polyethylene) extrusion molding services for industrial components, structural profiles, and tubing. Based in Shenzhen, China, we support product development teams and procurement departments by converting your technical designs into consistent, high-quality extruded parts for low-volume and mass-production projects.
Technical Specifications
Manufacturing Capabilities & Parameters
Our production facility utilizes precision extrusion lines to maintain tight tolerances and consistent cross-sectional profiles. We manage the entire process, from custom die design and material sourcing to secondary fabrication and assembly.
| Capability | Specification |
|---|---|
| Primary Process | HDPE Profile & Tube Extrusion |
| Material Grade | Virgin & Recycled HDPE (High-Density Polyethylene) |
| Typical Tolerance | ±0.10–0.50 mm (depending on geometry) |
| Output Shapes | Custom profiles, conduits, tubing, channels, and rails |
| Secondary Operations | Cutting to length, drilling, punching, printing, and assembly |
| Production Volume | Small-batch runs to high-volume industrial supply |
Engineering Support & DFM
Extrusion requires careful consideration of flow dynamics and material shrinkage. Our engineering team provides Design for Manufacturing (DFM) feedback on your drawings to help you:
- Minimize wall thickness variations to prevent warping.
- Design efficient mounting features or snap-fits within the profile.
- Optimize material usage to reduce unit costs without sacrificing structural performance.
Material Advantage
Why Choose HDPE for Your Project
HDPE is a preferred material for industrial applications due to its high strength-to-density ratio and chemical resistance. Our extrusion services allow you to leverage these properties across demanding operating conditions.
Ideal for fluid handling, laboratory equipment, and agricultural components exposed to aggressive compounds.
High impact resistance and low moisture absorption for outdoor or harsh environments without degradation.
Excellent for guide rails, stiffeners, and protective housings in industrial automation equipment.
Commonly used in cable management, wiring raceways, and conduit systems requiring non-conductive properties.
Target Industries
