We machine a wide range of engineering and commodity plastics, including:
ABS (good toughness, moderate cost)
Polycarbonate (PC) (high impact resistance, transparent options)
Acrylic (PMMA) (optical clarity, UV resistance)
POM (Delrin) (low friction, high stiffness)
Nylon (PA6, PA66) (wear-resistant, flexible)
PEEK (high-temperature, chemical-resistant)
PTFE (Teflon) (non-stick, chemical inertness)
HDPE & UHMW (low-cost, durable)
Standard tolerance: ±0.1 mm (±0.004")
High precision: ±0.05 mm (±0.002") or better (depends on material and part geometry)
3. How thin can CNC-machined plastic walls be?
Minimum recommended wall thickness: 1.0 mm (0.04")
For rigid plastics (e.g., PEEK, PC): Can go down to 0.5 mm with careful machining.
As-machined (light tool marks)
Sanded (smooth, Ra 1.6-3.2 μm)
Polished (glossy/mirror finish)
Bead blasted (matte texture)
Painting/coating (custom colors, textures)
Plastics are softer than metals, so improper machining can cause heat buildup, leading to warping or melting.
We use sharp tools, optimized feeds/speeds, and air cooling to minimize stress.
Annealing (heat treatment) can be applied for critical parts to relieve internal stresses.
Yes! We can machine:
Standard threads (M3, M4, UNC, etc.)
Self-tapping threads (for screws)
Helical inserts (for reinforced threads in soft plastics)
Preferred formats:
STEP (.stp) (best for 3D models)
IGES (.igs)
Parasolid (.x_t)
DWG/DXF (for 2D drawings)
STL (for prototyping, less precise)
Prototype lead time: 7-10 days
Production runs: 10-15 days (depending on quantity and complexity)
Rush service: Available (contact for expedited options)
