plastic molding
s. overmoulding Plastic injection mold having long service life is essential for improving efficiency and reducing cost.Now,the service life of injection mold is required to be used for more than one million times. hard tooling One reason for this is the increased performance requirements of theplastic molding finished articles. soft tooling With the emergence of high-speed molding machinery,the manufacturing of plastic products have speeded up.As the molding temperature is generally between 160 ~ 350 ℃,the poor fluidity and fast forming speed will make part of the molding surface temperature exceed 40
