Injection Rubber Moulding

Injection moulding machines are either vertically or horizontally run.

Injection moulding is a process where heated elastomer is injected into a closed cavity via a runner system.

Uncured elastomer is fed into the injection cylinder where it is preheated and accurately metered into the mould.

This is done by controlling the pressure, injection time and temperature.

The material is then held under high pressure and at a raised temperature to achieve curing.

When this is complete, the formed parts are ejected from the cavities.

Frequently Asked Questions

For injection rubber moulding, we recommend using high-quality silicone or natural rubber, depending on the application’s specific requirements. Silicone rubber is ideal for high-temperature applications and offers excellent flexibility and durability, while natural rubber provides superior elasticity and tear resistance for general-purpose use. Both materials ensure high-quality, long-lasting components tailored to meet our clients’ diverse needs.

The key difference between injection and compression moulding lies in their process and application. Injection moulding involves melting the material and injecting it into a mould under high pressure, which is ideal for creating complex shapes with precise dimensions and fine details. Compression moulding, on the other hand, places the material directly into the mould before applying heat and pressure to form the shape, making it more suitable for larger, less complex parts with slightly lower dimensional accuracy. Each method has its advantages, depending on the specific requirements of the product being manufactured.
