PC-ABS

PC-ABS is a high-performance engineering alloy that represents the perfect synergy between Polycarbonate and ABS. It offers the high impact strength and thermal stability of PC along with the exceptional processability and aesthetic versatility of ABS. This makes it the premier choice for demanding applications in the automotive, telecommunications, and medical industries. Jucheng Precision specializes in the precision CNC machining of PC-ABS, delivering complex prototypes and low-volume production parts with integrated features like snap-fits and threaded bosses. Our expertise in advanced surface finishing—including custom painting and texturing—ensures your PC-ABS components provide the rugged durability and premium look required for high-stakes product development.

Fabrication Guidelines for PC-ABS

Thermal Balance:
PC-ABS has a higher heat deflection temperature than standard ABS. 팁: We use high-speed spindles with optimized feed rates to prevent localized melting while maintaining high productivity.

Internal Stress Management:
The blend of two polymers can harbor internal stresses. 팁: For large or asymmetrical parts, we perform a stabilizing rest period between roughing and finishing passes to ensure zero warping.

공구 선택:
PC-ABS is tougher and slightly more abrasive than pure ABS. 팁: We use sub-micrograin carbide tools with polished flutes to shear the alloy cleanly, resulting in a superior surface finish (Ra 0.8μm).

Post-Processing Compatibility:
PC-ABS reacts exceptionally well to adhesives and paints. 팁: It is the best material for complex assemblies where multiple machined sections must be joined or cosmetically finished to a high standard.
