Type made by pouring different classification systems: (1) large outlet Die: runner and gate at the parting line, with products in plastic mold mold releasing together, to design the most simple, easy processing, low cost, So many people with large intake system operations. (2) a fine nozzle mold: runner and gate are not parting line plastic mold factory in Shenzhen, usually directly on the product, so you want to design a set of multi-outlet parting line, design is more complex, more difficult process, generally depending on product requirements and selection of fine nozzle system. (3) hot runner mold: This mold structure and fine nozzle much the same, the biggest difference is that in one or more of the flow channel has a constant temperature heat pump manifold plate and mouth, no cold material stripping and runner pouring port directly on the product, so the runner does not require a release, this system is also known as non-intake system plastic mold processing, saving raw materials for raw materials more expensive, higher product requirements, the design and processing difficulties, tooling costs higher. Synthetic plastic resin is the main component, the content in plastics is generally 40% to 100%. Due to the large content and nature of the resin often determines the nature of the plastic, so people often put plastic resin as a synonym. Such as polyvinyl chloride resin and PVC, phenolic resins and phenolic confused. In fact, resin and plastic are two different concepts. A raw polymer resin is raw, it is not only used to make plastics, but also paints, adhesives and synthetic raw materials. In addition to a tiny percentage of the plastic resin containing 100 percent, the vast majority of plastic, in addition to the main components of the resin, but also need to add other substances. 2, also known as filler filler filler plastic molds, which can improve the strength and heat resistance of plastics, and reduce costs. Such as phenolic resin after adding flour can greatly reduce costs and make Bakelite became one of the cheapest plastic, as well as significantly improve the mechanical strength. Fillers can be divided into organic fillers and inorganic fillers. The former such as wood flour, rags, paper and various textile fibers, such as glass fiber which, diatomaceous earth, asbestos, carbon black and the like.
