INTRODUCTION TO PLASTIC RESINS USED IN INJECTION MOLDING MACHINES

Plastic resin pellets are the primary raw materials used in the injection molding industry to manufacture a wide range of industrial and consumer products. Through the heating and injection process inside the molding machine, plastic pellets are melted and formed into precise and high-quality products.

Common Types of Plastic Resins
1. PP (Polypropylene)
High durability and lightweight
Good heat and chemical resistance
Applications: household products, packaging, plastic components
2. ABS (Acrylonitrile Butadiene Styrene)
Excellent surface finish and high rigidity
Easy to process and paint
Applications: electronic housings, automotive parts, cosmetic packaging
3. PE (Polyethylene)
Flexible and moisture-resistant
Cost-effective material
Applications: bottles, plastic bags, plastic pipes
4. PC (Polycarbonate)
High transparency and impact resistance
Excellent heat resistance
Applications: safety glasses, engineering components
5. PA / Nylon
High mechanical strength
Excellent wear resistance
Applications: gears, industrial and engineering parts
Plastic Resin Processing in Injection Molding
Feeding plastic pellets into the hopper
Heating and melting the material
Injecting molten plastic into the mold
Cooling and shaping the product
Removing the finished product from the mold
