Custom Compression Molding Process

The rubber compression process is a complete and continuous process that consists of 4 main stages, which offers efficient, tailored solutions for producing high-quality custom parts.

1.Mold Preparation
Thoroughly clean the mold and apply a release agent to the mold surfaces to ensure easy demolding and prevent adhesion.

2.Material Preparation and Loading
Cut the material (such as rubber or thermoset plastic) into precise pieces or preforms. Preheat the material to the appropriate temperature to improve flowability, then load the preheated material accurately into the lower mold cavity.

3.Pressing, Heating, and Cooling
Close the mold, apply high pressure to compress the material, and heat it to the required curing temperature. Maintain pressure and cooling until the material is fully cured and stable.

4.Demolding
After cooling, open the mold and carefully remove the formed custom compression molding part.

Rubber Compression Molding Surface Finishing

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

surface finish Glossy

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.
surface finish Semi-glossy

Semi-glossy

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

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.
surface finish Textured

Textured

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