Which materials are suitable for injection molding machines?

2025-09-23
Silicone injection molding machine is a commonly used plastic injection molding equipment for the production of various silicone products. It has the advantages of high precision, high efficiency and high stability, and it  is widely used in automotive, electronics, medical, electric power and other industries. The materials for injection molding in the silicone Injection molding machine mainly include: silicone, silicone rubber, liquid silicone and so on.


Silicone is a non-metallic material with excellent performance, with high temperature resistance, cold resistance, cold resistance, aging resistance and other characteristics, widely used in medical equipment, food packaging, electronic products, auto parts and other fields. In the silicone injection molding machine, the silicone material can be manufactured into various shapes of silicone products by injection molding, such as sealing rings, earplugs, watch bands and so on. Silicone injection molding machine has good material fluidity and stability, which can ensure the dimensional accuracy and surface quality of silicone products.


Silicone rubber is a kind of rubber polymer, with excellent elasticity, wear resistance, cold resistance, oil resistance, acid and alkali resistance, in the silicone injection molding machine can be made into a variety of silicone rubber products, such as sealing rings, rubber tubes, rubber pads and so on. The silicone rubber material has good fluidity, which can smoothly fill the mold cavity during the injection molding process, and maintain the dimensional accuracy and surface quality of the product.


Liquid silicone is a low viscosity liquid silicone material, with high transparency, low temperature hardening, high temperature resistance and other characteristics, in the silicone injection molding machine can be made with high transparency and soft touch silicone products, such as mobile phone case, protective cover, handle cover and so on. Liquid silica gel has good fluidity and self-leveling, can form a smooth surface in the mold, and maintain the dimensional accuracy and surface finish of the product.


In addition to silicone, silicone rubber and liquid silicone, other thermoplastic elastomer (TPE) materials can also be used for injection molding. Thermoplastic elastomer is a kind of rubber material that can be changed by hot processing, with good elasticity, softness and wear resistance, and can be manufactured in the silicone injection molding machine with a variety of elastic and soft touch products, such as sound absorption pads, car seals, electronic products accessories.


In short, the materials that can be injected into the silicone injection molding machine include not only silicone, silicone rubber and liquid silicone, but also other thermoplastic elastomer materials. These materials have good fluidity and stability, and can ensure the dimensional accuracy and surface quality of the product during the injection molding process. They are widely used in automotive, electronics, medical, power and other industries, providing high-quality and diversified silicone products for various industries.
