Common Raw Materials Used in Plastic CNC Carving

1. ABS: Good rigidity, easy‑to‑machine, ideal for enclosures, panels and signage; prone to melting if over‑heated.

2. PC (Polycarbonate): High‑impact‑resistant, transparent option, used for clear covers and protective frames.

3. Acrylic (PMMA): Crystal‑clear, high‑gloss. Perfect for engraved display signs, decorative panels; easy to chip under sharp cutting force.

4. POM (Delrin): High‑hardness, low‑friction, stable dimension. Suitable for gear, spacer and functional mechanical parts.

5. Nylon (PA): Wear‑resistant, flexible, applied for gaskets, custom‑bushings; easy to deform under heat.

6. PVC: Chemical‑resistant, mainly for chemical‑industry fixtures and nameplates.

1.What is the tolerance for plastic CNC-carved parts?

Typically, the range is ±0.02‑0.10 mm, influenced by the type of plastic and the design of the part.

2.Secondly, it is necessary to determine whether molds are required.

No mold is required for prototyping and small-batch orders.

3. What are the causes of acrylic chipping during the carving process?

Acrylic is known for its fragility. We employ single-flute cutters and meticulously optimize cutting parameters to avert chipping.

4. What is the most effective method for preventing plastic from melting?

To ensure optimal performance and durability, we reduce RPM, increase feed speed, and utilize air cooling to prevent thermal melting and burrs.

5.What surface finishes are available?

Our services include deburring, polishing, flame-polishing, sandblasting, and silk-printing.
