To some extent, it is a lot to ask how much a plastic injection mold costs. It is a like asking “How much does your car cost?” Will your mold be a Toyota or a Bentley? The factors that determine the cost you pay for a mold are a combination of several elements, including part dimensions, … Read more
Plastic refers to the numerous organic synthetic materials that are mostly polymers of high molecular weight. Currently, it is one of the 3 synthetic materials that are indispensable for our day-to-day life, while the other 2 are synthetic rubber and synthetic fiber. Natural or synthetic resin, the main ingredient of plastic, is often mixed with … Read more
Injection molding gate design Considerations: 1.A small opening between the runner and the mold cavity, of which the location, quantity, shape and size, etc. have a direct influence on product appearance, dimensional accuracy, physical characteristics and injection molding efficiency. 2.The size of an injection molding gate is dependent on product weight, material properties and gate … Read more
How the Hot Runner Systems Works The cold runner of a plastic injection mold refers to the section between the mold inlet and the gate. The molten plastic maintains its fluidity inside the runner by virtue of the injection pressure and its own heat. However, as a part of the molding material, the runner is … Read more
The Purpose of Injection Mold Cooling Systems The injection mold cooling system purpose is to ensure uniform cooling of the molded product and then eject the product out within a short period of time. The layout of the cooling channel plays an important role in the injection molding quality as well as the production cycle (cost) of … Read more
During the plastic injection mold trial process, defects like short-filling, trapped air burns, high internal stress, flow marks and weld lines often occur. For those problems, the first solution would be adjustment of the plastic injection molding process, and another consideration would be the reasonable design of the mold gate. Once both of these problems … Read more
Plastic Injection Mold Steel Selection for Molding Components Molding components refer to the mold parts or components which have a direct contact with the plastic materials to form a product, such as mold cavities, mold cores, sliders, inserts and lifters, etc. The steel quality of the molding components has a direct influence on mold quality … Read more
