condom produce Vulcanizing Process

The condom is dried and added with silica powder in blender, which automatically tumbles and feeds out condoms in a collection box, then carried to vulcanizer. After vulcanizing and cooling where thoroughly depowdered in each separate process, the vulcanized condoms are randomly sampled for the first visual inspection and physical property testing. This process makes the condom more durable to use it freely. The accepted condoms are sent to pinhole testing in the next process.

Each company has its own rule in the vulcanizing process, which also make each company’s quality and condom color a little different.
