Frequently Asked Questions
1. What types of plastics can be CNC machined?
We machine a wide range of engineering plastics, including ABS (toughness), Polycarbonate (impact resistance), Acrylic (clarity), POM (low friction), Nylon (wear-resistant), and PEEK (high-temperature resistance).
2. What tolerances can be achieved with CNC plastic machining?
Our standard tolerance is ±0.1 mm (±0.004"). For high-precision requirements, we can achieve ±0.05 mm (±0.002") depending on the material and part geometry.
3. How thin can CNC-machined plastic walls be?
The minimum recommended wall thickness is 1.0 mm. For rigid plastics like PEEK or PC, we can achieve 0.5 mm with specialized machining techniques.
4. What surface finishes are available for medical enclosures?
We offer as-machined, sanded (Ra 1.6-3.2 μm), mirror polishing, bead blasting for matte textures, and custom painting or UV coating.
5. Does CNC machining cause warping in plastic parts?
Plastics are heat-sensitive. We use sharp tools, optimized speeds, and air cooling to minimize stress. Annealing heat treatment is also available for critical parts to relieve internal stresses.
6. What file formats are required for a quote?
We prefer STEP (.stp) or IGES (.igs) for 3D models, and PDF or DWG for 2D drawings indicating tolerances and thread requirements.
