First, our worker colleague will use the dispersion mixer（the first machine picture） to mix rubber raw materials and chemical raw materials evenly. The process is like kneading the flour before making bread. Second, the worker will make the mixed rubber into a suitable sheet with an open mixer（the second machine picture）. Rubber sheet in the third picture. Then the rubber sheet can be used for vulcanization productio

Normally before vulcanization, our worker colleague will cut the unvulcanized rubber sheet to diferent sizes according product dimension. Sometimes it will be preformed by extruder. All of these are to facilitate vulcanization production and save time.

We achieve this by plating Teflon on the mold surface, please reference below picture.
