We achieve tolerances as tight as ±0.0005 inches (0.0127mm) on precision CNC machined plastic parts, depending on material and geometry. Standard commercial tolerance is ±0.005 inch. We discuss achievable tolerances during DFM review before production begins. See our CNC machining page for full specifications.

Bead blasting, vapor polishing (for optically clear acrylic), painting, silk screening, laser engraving and marking, anti-static treatments. Surface roughness down to Ra 0.4µm for critical applications. Learn more on our capabilities page.

Our 5-axis CNC machining centers handle parts up to 40″ x 20″ x 20″ (1000mm x 500mm x 500mm). CNC turning: 0.125″ to 18″ diameter (3mm to 450mm). Larger parts via plastic welding and assembly.

Yes. Beyond CNC machining, we offer plastic welding (hot gas, ultrasonic), solvent and adhesive bonding, threaded insert installation (heat-stake and press-fit), and complete kitting and assembly. Turnkey plastic assemblies ready for your production line. Ref: Machine Design Magazine.

Ordering & Lead Times

Ordering & Lead Times Plastic Machining FAQ

Standard lead times: 5 to 15 business days depending on part complexity, material, and quantity. Rapid prototyping: 48-hour turnaround. Rush orders: as little as 3 business days. Every quote includes a firm delivery date. Request a quote for your estimate.

Absolutely. Single-piece prototypes to 10,000+ parts per month. High-mix/low-volume cells and dedicated production lines. Many clients start with prototype validation and transition to production with us. See injection molding for high volume.
