Problems solved by technology

At the same time, it was found that in the process of product manufacturing, a large amount of static electricity will be generated. Although the PTFE coating can effectively solve the problem of mold release, it cannot solve the release of static electricity, and the generation and accumulation of static electricity is an objective existence in nature. Deposits can cause phenomena such as sparking and burning
Therefore, it has brought great safety hazards to scientific research and production.
