Single parting surface injection mold When the mold is opened, the movable mold and the fixed mold are separated to take out the plastic parts. This is called a single parting surface mould, also called a double-plate mold. It is the simplest and most basic form of injection mould. It can be designed as a

Cavity layout. The number of cavities and their arrangement are determined based on the geometric structure characteristics of the plastic part, dimensional accuracy requirements, batch size, difficulty in mold manufacturing, mold cost, etc. 2. Determine the parting surface. The position of the parting surface should be conducive to mold processing, exhaust, demoulding and molding operations,

Integrated hinge Product logos are generally placed on the flat inner surface of the product in a raised form. Choosing a surface where the normal direction may be consistent with the mold opening direction can avoid strain. Due to the unevenness and uncertainty of shrinkage during injection molding, the accuracy of injection molded parts is

Silver Streaks Definition When plastics are disturbed by gas during the mold filling process, silver streaks or tiny bubbles often appear on the surface of the product or bubbles are formed in the thick wall of the product. The main source of these gases is that the raw materials contain moisture or volatile substances or
