Injection mold factory | Rui Shi plastic mold (certified) | Chang injection molds

 Injection mold 1. It provides a channel injection mold, molten plastic from the injection cylinder (barrel) to the mold cavity. 2. It allows the air trapped inside to escape when the mold is closed. If the air can not escape (ventilation) molded parts contain voids (air bubbles), and poor surface finish. 3. cooling molding, until it ends. Injection mold temperature is controlled injection mold manufacturers, because it is the most important, in the injection molding at the correct rate of cooling in order to avoid deformation and pressure. In most systems the circulation, by drilling with a similar car engine cooling system of the mold channel. 4. When finished molding ejector pushed from the plastic mold. The manufacture of plastic injection mold injection mold material of choice not only have superb refined manufacturing process, as well as assistance, material direct impact on the quality of the material effects of injection molding, so companies in the production process, its materials were analyzed . The main components of the injection mold is a synthetic resin, its content in plastics is above one-half or even one hundred percent. Due to the large content, the nature of the resin often determines the nature of the plastic, which is why people put plastic resin as a synonym for the sake of. In fact, plastics and resins are in fact two different concepts injection mold design, original polymer resin is a raw, it is not only used to make plastics, but also paints, adhesives and synthetic materials. In addition to containing a portion of the plastic resin, there are many other substances. Such as fillers, it is to improve the strength and heat resistance of plastics, and low cost. For example: After adding flour phenolic resin can greatly reduce costs and make Bakelite became one of the cheapest plastic injection mold, as well as significantly improve the mechanical strength. Organic fillers and inorganic fillers are divided into two types of fillers, the former as wood flour, Scattered, paper and various kinds of fibers, the latter as glass fibers, diatomaceous earth, asbestos, carbon black and the like.
