Plastic Machining Design Guidelines

Optimize your plastic parts for CNC machining with these design best practices that ensure manufacturability, quality, and cost-effectiveness.

Design Best Practices

  •   Wall Thickness: Maintain uniform wall thickness to prevent warping and stress concentration.
  •   Radii and Fillets: Use generous radii (minimum 0.5mm) to reduce stress and improve surface finish.
  •   Draft Angles: Not required for machining, allowing for true vertical walls and precise fits.
  •   Feature Size: Minimum feature size should be at least 2x the material thickness for stability.

Design Considerations

  •   Heat Generation: Consider cutting speeds and feeds to minimize heat buildup and material degradation.
  •   Clamping Areas: Provide adequate material for secure workholding without part distortion.
  •   Tool Access: Ensure all features are accessible to cutting tools with appropriate clearances.
  •   Material Direction: Consider material grain direction for optimal strength and surface finish.

Frequently Asked Questions

Get answers to common questions about our CNC plastic machining services and capabilities.

What tolerances can you achieve with CNC plastic machining?

Our CNC plastic machining services can achieve tolerances as tight as ±0.01mm (±0.0004″) depending on the plastic material, part geometry, and specific requirements. For most standard applications, we maintain tolerances of ±0.05mm (±0.002″) with excellent repeatability. Our temperature-controlled environment and precision measuring equipment ensure consistent accuracy across all production runs.

What types of plastics can you machine?

We machine over 100 different plastic materials including ABS, Acetal (Delrin/POM), Acrylic, HDPE, Nylon, PEI (Ultem), PEEK, PET, Polypropylene, Polystyrene, PVC, and many engineering-grade thermoplastics. Our experienced team understands the unique machining characteristics of each material and optimizes cutting parameters, tooling, and thermal management to achieve superior results.

How do you prevent heat damage during plastic machining?

We employ several strategies to prevent heat damage including optimized cutting speeds and feeds, sharp cutting tools, flood coolant systems, and temperature monitoring throughout the machining process. Our CNC machines are equipped with advanced cooling systems, and we use specialized tooling designed specifically for plastic materials to minimize heat generation and ensure dimensional stability.

Can you machine transparent plastics without clouding?

Yes, we specialize in machining transparent plastics like acrylic, polycarbonate, and PETG while maintaining optical clarity. We use diamond-tipped tools, controlled cutting parameters, and specialized finishing techniques including vapor polishing for acrylics to achieve crystal-clear surfaces. Our process eliminates stress marks and maintains the original transparency of the material.

What surface finishes are available for plastic parts?

We offer various surface finishes including as-machined, polished, vapor polished (for acrylics), textured, painted, and coated finishes. Surface roughness can range from Ra 0.1μm for polished surfaces to custom textures as required. We can also prepare surfaces for ultrasonic welding, bonding, or other secondary assembly processes based on your specific application needs.

Do you provide material certificates and quality documentation?

Yes, we provide comprehensive quality documentation including material certificates, dimensional inspection reports, and compliance certificates for FDA, RoHS, and other industry standards as required. Our ISO 9001 certified quality management system ensures full traceability from raw material to finished part, with detailed documentation for critical applications in medical, aerospace, and food-grade industries.
