Why Plastic Parts Need Special Attention
Cutting Heat
Excessive heat may soften the material, affect dimensions or reduce edge quality.
Clamping Pressure
Flexible or thin-wall parts may deform when excessive holding force is applied.
Internal Material Stress
Removing a large amount of material may release internal stress and change the finished geometry.
Moisture Absorption
Nylon and certain other polymers may change dimensions according to their moisture condition.
Burrs and Chipping
Sharp tools and suitable cutting parameters help control burrs, cracking and chipped edges.
Our Plastic Machining Approach
- Review the polymer grade and material condition.
- Select suitable cutting tools, speeds and feed rates.
- Control heat accumulation during machining.
- Use appropriate clamping for thin or flexible parts.
- Consider roughing and finishing for stress-sensitive geometry.
- Inspect critical dimensions after the component has stabilized.
Typical CNC Plastic Components
Plastic and Metal Parts in One Assembly
Many industrial assemblies combine CNC-machined plastic components with aluminum, stainless steel or other metal parts. Hole positions, mating surfaces, fastener interfaces, operating clearance and thermal expansion should be reviewed together.
We can manufacture plastic and metal components according to the same assembly requirements, helping customers reduce dimensional coordination between different suppliers.
Information Needed for Quotation
- Latest STEP, IGES or other available 3D file
- PDF drawing with critical dimensions and tolerances
- Plastic grade, color and material specification
- Prototype and estimated batch quantities
- Surface, appearance and inspection requirements
- Operating temperature or chemical exposure
Customer drawings, CAD files, samples and technical specifications are treated as confidential project information. NDA support is available for OEM and ODM projects.
