FAQ

Q1: How do you prevent dimensional distortion or warping when machining soft or high-expansion plastics like PTFE or Nylon?

A: Engineering plastics possess higher thermal expansion coefficients than metals. At Qingdao Compass Hardware, we counter this by utilizing sharp, polished cutting tools designed specifically for plastics, optimizing feed rates to reduce heat buildup, and performing specialized post-machining stress-relief annealing when working with thick-walled or highly complex geometries.

Q2: Can you achieve optical transparency for custom Polycarbonate (PC) or Acrylic (PMMA) CNC parts?

A: Yes. Standard CNC machining leaves a translucent or matte finish on plastic surfaces. To achieve optical clarity for electronic lenses, fluid viewports, or medical housings, we offer professional secondary finishing options including diamond machine polishing, manual buffing, and specialized vapor polishing.

Q3: What quality control protocols do you implement for critical medical or aerospace plastic components?

A: We adhere to a rigid 3-stage QC loop. We verify raw material traceability via material certifications during incoming inspection. In-process inspection monitors critical features on our Coordinate Measuring Machine (CMM). Finally, we conduct 100% dimensional auditing against your CAD blueprints and can provide full FAI (First Article Inspection) reports per AS9102 or PPAP standards upon request.

Q4: Do you support rapid prototyping for low-volume plastic designs before moving to mass production?

A: Absolutely. Our CNC plastic machining services are ideal for bridging the gap between R&D and mass manufacturing. We support flexible order quantities—ranging from a single functional prototype for fit-testing to low-volume production runs of thousands of pieces, saving you expensive injection molding tooling costs.
