Frequently Asked Questions
What types of plastics can be CNC machined?
We machine a wide range of engineering plastics including ABS, Polycarbonate (PC), Acrylic (PMMA), POM (Delrin), Nylon (PA6/PA66), PEEK, PTFE (Teflon), and HDPE.
What tolerances can be achieved with CNC plastic machining?
Standard tolerance is ±0.1 mm (±0.004"). High precision requirements can reach ±0.05 mm (±0.002") or better depending on material and part geometry.
What surface finishes are available for medical equipment parts?
Options include as-machined, sanded (Ra 1.6-3.2 μm), polished (mirror/glossy), bead blasted (matte), and custom painting or coatings.
Can you machine threaded holes in plastic parts?
Yes, we can machine standard threads (M3, M4, UNC, etc.), self-tapping threads, and install helical inserts for reinforced threads in softer plastics.
How long does the CNC plastic machining process take?
Prototype lead times are typically 7-10 days. Full production runs usually take 10-15 days depending on complexity and quantity. Rush services are available.
Why choose CNC machining over 3D printing for these components?
CNC machining provides higher accuracy, superior material strength (fully dense), and much smoother surface finishes suitable for high-precision functional parts.
