Kneading process

Industrial rubber is made by combining raw material rubber with a number of other materials and kneading them together.
Rubber materials with a variety of characteristics can be made by changing the formulation of the raw material rubber.

1Addition of ingredients and kneading

A variety of materials are kneaded into industrial rubber. Raw materials are added to the kneader and kneaded together after being cut and weighed.

2Rolling

This important task requires an extremely high level of skill. Rubber material is finished during this process, which determines the quality of the resulting material.

3Completion

The material is shaped so that it can be supplied to the equipment used in the next process. If the next process is injection molding, the rubber is cut into ribbons and boxed up.

Chemical treatment

This process creates a coating by treating the surface of metal parts with chemical agents.
It serves to increase corrosion resistance and strengthen cure adhesion.

1Loading

Materials are loaded into the machine used to chemically treat metal parts.

2Blasting → Defatting → Water rinse → Surface adjustment → Chemical conversion → Water rinse → Drying

Dirt is removed from the surface of the metal hardware, which undergoes blasting to activate its surface. Then chemical agents are used to create a chemical coating.

3Completion

Steps from blasting to generation of the chemical coating and drying are performed automatically. Then the treated hardware is ejected from the system.

Adhesive application, molding, and post-processing

Upper arm bushing

Metal hardware that has been coated with an adhesive is placed in a mold into which rubber is then injected to form a rubber product with integrated hardware.

1Adhesive application

An adhesive is applied to a chemically treated metal part, which is then allowed to dry.

2Molding

Metal hardware that has been coated with an adhesive is placed in a high-temperature mold into which rubber is then injected. The product undergoes vulcanization and adhesion (cure adhesion) and is ejected from the mold.

3Drawing and painting processes

Molded products are finished and inspected. Then they undergo post-processing such as drawing and painting.

4Completion

This sequence of steps is used to manufacture finished rubber parts.
