How To Choose The Plastic Material For Machining Mechanical Parts?

DALIAN, China - Oct. 31, 2022 - PRLog -- 1. ABS Plastic

ABS resin is one of the five synthetic resins. It has excellent impact resistance, heat resistance, low temperature resistance, chemical resistance and electrical performance. It also has the characteristics of easy processing, stable product size, good surface gloss, easy painting and coloring. It can also carry out secondary processing such as surface spraying metal, electroplating, welding, hot pressing and bonding. It is widely used in machinery, automobiles, electronic appliances, instruments and meters Textile, construction and other industrial fields, is a very wide range of thermoplastic engineering plastics. ABS is usually light yellow or milky white granular amorphous resin. ABS is one of the most widely used engineering plastics。

2. Nylon PA6

The material has the most superior comprehensive properties, including mechanical strength, stiffness, toughness, mechanical shock absorption and wear resistance. These characteristics, together with good electrical insulation capacity and chemical resistance, make nylon 6 a "universal" material for the manufacture of mechanical structural parts and maintainable parts.

3. Nylon PA66

Compared with nylon 6, it has better mechanical strength, stiffness, heat resistance, wear resistance and creep resistance, but its impact strength and mechanical shock absorption performance are reduced, so it is very suitable for automatic lathe machining. PA66 is more widely used in the automotive industry, instrument housings and other products requiring impact resistance and high strength.

4. Nylon PA12

The scientific name of PA12 is polydodecalactam, also known as nylon 12. The basic raw material for polymerization is butadiene, which can depend on petrochemical industry. It is a semi crystalline crystalline thermoplastic material. Its characteristics are similar to PA11, but its crystal structure is different. PA12 is a good electrical insulator and like other polyamides, it will not affect the insulation performance due to moisture. It has good impact resistance and mechanical and chemical stability. PA12 has many improved varieties in plasticizing and strengthening properties. Compared with PA6 and PA66, these materials have lower melting point and density, and have very high moisture regain. PA12 has no resistance to strong oxidizing acids. Typical application scope of nylon 12: water meter and other commercial equipment, cable sleeve, mechanical cam, sliding mechanism, photovoltaic backplane and bearing, etc.
