1. Common adverse phenomena are: wrinkling and wrinkling of the product surface.

Surface wrinkles: irregular wrinkles formed on the surface of the product, mainly in the front part of the thinner wall. Due to the suction of release agent and compressed air, the high pressure enclosed in the front section pushes up the surface of the product and causes this phenomenon to occur.

Wrinkling: The cylindrical part near the insert, the surface of the skin film wrinkling phenomenon wrinkled surface part, according to the occurrence of the state of difference.


2. A solution to the problem

Surface wrinkle solution: exhaust thoroughly, remove excess release agent. Adjust the position of the high speed and high pressure zone to prevent the cooling of the solution;

Wrinkle solution: Preheat the mold, it is very important to produce under the set temperature conditions, and set the mold temperature in the appropriate range.
