Comparison of CNC Machining Materials

PC+ABS is a blend-modified material that combines the advantages of both materials. It not only inherits the high impact resistance of PC but also the material strength of ABS, while improving its heat resistance. It is often used in electronic product casings, automotive interiors, consumer products, and more.

High Impact Polystyrene (HIPS) is a low-cost and easily processable plastic material. It is often used in the manufacturing of low-strength structural components in scenarios where comprehensive requirements for a material’s impact resistance, processability, and cost are required. Additionally, with its excellent dimensional stability and ease of being painted and bonded, it has become an ideal material for prototyping.

PC (polycarbonate, commonly known as bulletproof glue) is inherently pale yellow or colorless and transparent, featuring hardness, toughness and luster. It boasts prominent advantages: with a light transmittance of 90%, it not only has good mechanical strength but also excellent impact resistance, along with outstanding heat resistance and weatherability.

Acrylic (also known as polymethyl methacrylate, PMMA) boasts not only excellent optical performance but also outstanding UV resistance. With a light transmittance of up to 92%—comparable to glass—it has become a popular material in scenarios ranging from neon signs in shopping malls and display case panels in museums to precision optical lenses and stage light covers.

Low carbon steel (with carbon content not exceeding 0.25%) is one of the most commonly used types of steel in both industry and daily life, thanks to its excellent plasticity, weldability, and low cost. It is widely applied in components such as pistons, screws, and drive shafts. However, due to its limited strength, it usually requires post-treatment.
