As we all know, the injection molding is a tool for the producing of plastic products. On the other hand, the most famous injection molding company in china which name is Duratec has told us that the plastic injection molding is also the tool which could give the plastic products complete structure and precise dimensions. Today, the china injection molding manufacture which website is would tell you the types and some description about the injection molder.

From the forming characteristics, we could found that the china injection molding could be divided into thermo set and thermoplastic plastic mold. If we distinguish them by transfer molding process, they could be divided into molding, blow molding, cast molding, thermoforming mold, pressure mold, injection molding and so on. In addition, the hot pressure mold can be divided into overflow, semi-overflow style and non-overflow type. The injection molding can be divided into cold runner mold and hot runner mold. If the distinguish could be taken by way of loading and unloading, the plastic molding can be divided into mobile type and fixed type.

The engineer from the Duratec has said that the precision injection molding was composed of two parts which have included the movable mold and fixed mold. The movable mold has been mounted on the movable platen of the injection molding machine. On the other hand, the fixed mold has been mounted on the fixed template of injection molding machine stationary. During injection molding, the composition of movable mold with the fixed mold has finished the casting system and closed cavity. We could take the plastic products when the movable mold and fixed mold has been separated.

Although the structure of the mold may be in different types and changing due to the different performance and shape of the plastic and structure of plastic injection molder, the basic structure is the same. The injection molder is mainly consisted by gating system, thermostat systems, molded parts and structural parts. The gating system and molded parts are in direct contact with the plastic parts and with the change of plastic and products. These parts are the most complex part which has the greatest change and requires precision machining finish.

The gating system of the china injection molding is part which plastic nozzle into the cavity from the front portion of the flow channel. The gating system has included the main flow channel, cold-slug, diversion channel, gate and so on. The molded part is the parts which could shape of the various parts constituting products. This includes the dynamic simulation, the fixed mold cavity, core, forming rod and the exhaust vent. peek injection
