Plastic

Plastic materials are widely used in various manufacturing processes such as CNC machining, rapid tooling, plastic injection molding, die casting, and 3D printing. Commonly used plastics for these processes include ABS, PC, Nylon, PP, PE, POM, PVC, TPU, PBT, and PMMA.


Each plastic material has its unique properties such as strength, flexibility, heat resistance, and chemical resistance, which make them suitable for different applications. For instance, ABS is commonly used for 3D printing due to its strength and flexibility, while PC is often used for CNC machining due to its high heat resistance. Plastic injection molding and die casting processes typically use materials with high strength and durability, such as Nylon and POM. Rapid tooling often uses materials like PP and PE, which are affordable and easy to manufacture. Overall, plastic materials play a crucial role in many manufacturing processes, providing versatility and customization options for a wide range of products.
