The mechanism and countermeasures of hot press pores:

①The SMC molding material contains a large amount of air and the volatile content is large, and the exhaust is not smooth; the thickening effect of the SMC material is not good, and the gas cannot be effectively driven out. The above causes can be effectively controlled by a combination of increasing the number of vents and cleaning the mold.

②The feeding area is too large, appropriately reducing the feeding area can be controlled. In the actual operation process, human factors may also cause trachoma. For example, if the pressurization is too early, it may be difficult for the gas wrapped in the molding compound to be discharged, resulting in surface defects such as pores on the surface of the product.
