First, it may be a lack of sulfur.
It is recommended to unlock and then see if the plastic material contains water? Very much like the lack of plastic pressure caused by the appearance of the problem, cut open to see if there is also a hole, if there is a lack of material. If there is no need to consider whether the mold temperature is too high, the surface of the hot, this thick product, curing temperature is not too high.
Second, is not enough time to cure.
Third, the amount of natural rubber is insufficient.
This may be the problem of mold runner, probably the flow channel of the mold cavity is a bit blocked.
Second, how to solve these problems?
First, sulfur deficiency. More than a few times the pressure exhaust.
Second, curing time is not enough. Appropriate increase in curing time.
Third, the amount of natural rubber is insufficient. Increase the weight of the compound.
