Rubber Injection Molding Surface Finishing

Proper surface finishing will improve the injection molded parts' quality. Zhongde offers a wide range of surface treatment options. These efficient surface finishes improve the part's functions and aesthetic appeal.

Glossy

A-grade finish is smooth and highly reflective, giving the product a shiny appearance. It’s often used for products where aesthetics are important.

Learn Glossy Finish

Semi-glossy

The B-grade finish is less reflective than glossy but still has a smooth and somewhat shiny appearance.

Learn Semi-glossy

Matte

C-grade finish is non-reflective and has a dull appearance. It’s often chosen for parts where glare or light reflection is undesirable.

Learn Matte Finish

Textured

D-grade finishes are intentionally rough or patterned. They can provide a better grip or a unique appearance to the product.

Rubber Injection Molding Process

The rubber injection molding process is a complete and continuous process that consists of 4 main stages, which directly determine the quality of a custom rubber molded product.

1. Filling stage
The filling is the first step in the entire rubber injection cycle. The time is calculated from the beginning of injection when the mold is closed until the mold cavity is filled to about 95%.

2. Pressure-holding stage
The role of the holding pressure stage is to apply continuous pressure to compact the melt and increase the density of the rubber, thus compensating for the shrinkage behavior of the rubber.

3. Cooling stage
In rubber injection mold, the design of the cooling system is very important. A well-designed cooling system can greatly shorten the molding time, improve injection molding productivity, and reduce costs.

4. Demoulding stage
Demoulding is the last step in an injection molding cycle. There are two main ways of release: ejector rod release and stripper plate release.
