1, High density polyethylene (HDPE) and low density polyethylene (LDPE)
In injection molding, high-density polyethylene (HDPE) and low-density polyethylene (LDPE) are one of the most commonly used plastic materials. These two materials have many advantages, such as high ductility, good tensile strength, strong impact resistance, moisture absorption resistance, and recyclability. HDPE, due to its high strength and hardness, is often used to manufacture components that require significant stress, such as pipes, containers, etc; LDPE, on the other hand, has a wide range of applications in packaging films, wires and cables due to its good flexibility and low temperature resistance.
2, Acrylonitrile Butadiene Styrene (ABS)
Acrylonitrile Butadiene Styrene (ABS) is a thermoplastic made by copolymerizing three monomers: acrylonitrile, butadiene, and styrene. ABS plastic is known for its excellent mechanical properties, impact resistance, and creep resistance, as well as good processability and surface glossiness. These characteristics have made ABS plastic widely used in fields such as automobiles, electrical appliances, electronics, etc., such as automotive interior and exterior parts, TV and refrigerator casings, etc.
3, Polycarbonate (PC)
Polycarbonate (PC) is a thermoplastic with high transparency, heat resistance, and impact strength. PC plastic is known as "bulletproof glass" due to its excellent performance, and has a wide range of applications in optical lenses, electronic components, safety protection equipment, and other fields. In addition, PC plastic also has good dimensional stability and processing performance, which can meet the production needs of high-precision and high demand products.
4, Nylon (PA)
Nylon (PA) is an engineering plastic composed of polyamide resin, which has excellent properties such as high strength, high toughness, wear resistance, and corrosion resistance. Nylon plastic has high crystallinity and good mechanical properties, so it is widely used in the manufacturing of structural components and wear-resistant parts, such as bearings, gears, transmission components, etc. In addition, nylon plastic also has good self-lubricating properties and low temperature resistance, and is widely used in components that require low-temperature operation.
5, Polyoxymethylene (POM)
Polyoxymethylene (POM), also known as Saigang material, is an engineering plastic with excellent mechanical properties and wear resistance. POM plastic has high elastic modulus, rigidity, and surface hardness, and is known as a "competitor to metals". POM plastic has unique advantages in manufacturing precision parts, gears, bearings, etc. due to its low friction coefficient, good self-lubricating properties, and excellent solvent resistance. In addition, POM plastic also has good thermal stability and weather resistance, which can meet the needs of working in high temperature or harsh environments.
6, Other commonly used injection molded plastics
In addition to the common injection molded plastics mentioned above, there are also other materials that have been widely used in injection molding processing. For example, polypropylene (PP) is used in the manufacturing of automotive parts, household appliances, etc. due to its good fluidity, formability, and heat resistance; Polystyrene (PS) is used to manufacture optical instruments, electrical enclosures, etc. due to its excellent optical and electrical properties; Polyethylene terephthalate (PET) is widely used in fields such as beverage bottles and food packaging due to its excellent barrier properties and transparency.
