Today, the first punch bushing manufacturer will take you to understand the three major causes of mold sticking and the solutions.
1. Mold problem
The first punch bushing manufacturer tells you that the mold itself is rough or mishandled. The solution is galvanized, chrome-plated, and Teflon-plated.
2. There is dirt in the mold
The solution is to pick a small amount clean with a needle. The main reason for this problem is the lack of sulfur. After the lack of sulfur, there is a small amount of glue that is not cleaned up, and the glue sticks to the rubber again. The accumulation of more and more makes the mold unable to produce normally. The first punch bushing manufacturer tells you that the more you spray the mold release agent, the more silicone will accumulate in the mold, which will cause the mold to stick more seriously. The solution is to wash the mold.
3. The problem of rubber compound formulation
First of all, the hot tear strength of the rubber itself is poor. The first punch bushing manufacturer tells you that when the mold is rough, it is easy to break the small particles of the rubber in the mold, and the accumulation will cause the mold to stick. The solution is to use some For rubber with high hot tear strength such as natural rubber, clean the mold.
The other is that the formula itself is too viscous and easy to stick to the mold. The solution is to add an internal mold agent or spray an external mold release agent. However, it is not recommended to use a release agent, because any release agent will accumulate silicon, and too much silicon will stick to the mold. The first punch bushing manufacturer tells you that the mold that sprays the release agent must be electrically crossed, otherwise the mold will stick to the mold after washing, which will still damage the mold and affect the service life.
