What Is Plastic

Common Plastic Materials

• Commodity Plastics (PE, PP, PVC, PS, etc.): Low cost and high output, widely used in packaging, consumer goods, and disposable products.

• Engineering Plastics (PC, ABS, PA, POM, etc.): High mechanical strength and excellent heat and chemical resistance, commonly used in automotive components and electronic housings.

• High-Performance Plastics (PEEK, PTFE, UHMWPE, PI, etc.): Excellent heat resistance, chemical resistance, and mechanical performance, found in aerospace, medical implants, and high-end electronics.

types of plastic moulding Methods

The main types of plastic moulding processes include:

1. Extrusion: Molten plastic is continuously forced through a die to form pipes, profiles, or films.

2. Blow Molding: Molten plastic is blown into a hollow shape, such as bottles and containers.

3. Compression Molding: Used for thermosetting plastics and large parts, common in brake pads and insulating components for automotive applications.

4. Injection Molding: The most widely used of the types of plastic moulding processes, where molten plastic is injected under high pressure into a mold—highly automated and efficient.                                                                                                                                                                                                                                                                                                                                                                                              

   Choosing the right types of plastic moulding process can improve production efficiency while optimizing cost structure and product performance. JSJM is proficient in various types of plastic moulding techniques and can tailor the optimal solution for each client.

   Applications of high precision plastic injection molding with High-Performance Materials

   For technical high-performance materials, high precision plastic injection molding is often required to ensure dimensional accuracy and surface quality:

   • PEEK: Through high precision plastic injection molding, tolerances of ±0.02 mm can be achieved, suitable for aerospace parts and medical implants.

   • PTFE: Injection molding under controlled high temperature and pressure, ideal for high-precision seals and low-friction components.

   • UHMWPE: Combined with high precision plastic injection molding to produce wear-resistant, impact-resistant parts for medical devices and protective equipment.

   • PI/PEI: In electronic packaging and high-temperature insulation, high precision plastic injection molding achieves micron-level dimensional control to guarantee electrical performance and reliability.

   Reliable high precision plastic injection molding requires multi-cavity temperature-controlled molds, precision injection equipment, and strict control of injection pressure, melt temperature, and cooling rate.
