Hot press crack

This phenomenon mostly occurs in products with inserts. The reason may be. The structure of the inserts in the product is unreasonable; the number of inserts is too much; the demoulding method is unreasonable, and the thickness of each part of the product is too different. The solution is to change the structure of the product under permitted conditions, and the insert must meet the requirements of molding; reasonably design the demoulding mechanism to ensure the average ejection force.
