Molded Part Process

Injection Molding

Injection molding process By using compound rubber that has not been vulcanized Flow through the screw to keep the compound tires in the machine Causing the compound tire to have higher temperatures so it can be injected into the mold Use heat to ripen the rubber The mold is designed to use both Hot Runner and Cold Rubber. The design depends on the characteristics of the rubber parts used in the production. The production of Injection Molding is suitable for the production of a large number of rubber parts. In order to get cheaper production costs Complicated rubber parts And has the advantage of the production period and the excess rubber scraps less

Compression Molding
Extrusion process By preparing weight compound rubber to be placed on a mold in each cavity and using pressure and heat compression methods Within the time limit In order to ripen parts of the rubber Compression molding process is suitable for the production of small rubber parts. Uncomplicated shape

Transfer Molding
The compression molding process is very close to Compression Molding. The only difference is that the mold designed Suitable for the production of a small number of rubber parts But has a more complex shape

In each production design, aside from considering the characteristics of rubber parts Compound rubber formulas designed for properties And the production process Production costs are also equally important. Therefore, in each production design, we have a Product Engineer team to help design the production so that customers get the right rubber parts. Spec. Reduce production costs as much as possible.
