Product Introduction


gas injection molding process.JPG

Plastic molding is also called injection molding. It is an injection molding method. The advantages of injection molding process is the production of high speed and high efficiency, automation, and more varieties, shaped by the simple, size from big to small, and accurate product size, easy product upgrading, can become a part of complex shape, injection molding is suitable for mass production with complex shape products etc. processing field. Under certain temperature, the plastic material is completely melted by screw stirring, and then the mold is obtained by high pressure injection into the die cavity, and then solidified and cooled, and then the molding product is obtained. This method is suitable for mass production of complex parts, and it is one of the important processing methods.

Thermosetting plastics and rubber molding process also includes the same process, but the barrel temperature is lower than thermoplastics, injection pressure is higher, the mold is heated, the injection of material in the mold after curing or vulcanizing process, and then take the heat off the film.

Nowadays, the trend of processing technology is developing in the direction of high and new technology. These technologies include micro injection molding, high filling composite injection molding, water assisted injection molding, mixed use of various special injection molding processes, foam injection molding, mold technology, simulation technology, etc..

Product Feature And Application


gas injection molding process2.JPG

Barrel temperature: injection molding process need to control the temperature of the barrel temperature, nozzle temperature and mold temperature, etc.. The first two kinds of temperature mainly affect the plasticization and flow of plastics, and the latter mainly affects the flow and cooling of plastics. Each kind of plastic has different flow temperature, with a plastic, or as the source of different grades, the flow temperature and decomposition temperature is different, this is because the average molecular weight and molecular weight distribution caused by the different plasticizing process in different types of plastic injection machine in is different, so the selection of materials the cylinder temperature is not the same.

Nozzle temperature: the nozzle temperature is usually slightly lower than the maximum temperature of the barrel, this is to prevent the melt in the nozzle may occur through the salivation phenomenon "". Nozzle temperature can not be too low, otherwise it will lead to early melting of the melt and nozzle clogging, or because the early condensate injection mold cavity and affect the performance of the product. Mold temperature: mold temperature has a great influence on the internal performance and apparent quality of the product. The mold temperature depends on the crystallinity of the plastic, the size and structure of the product, the performance requirements, and other process conditions (melting temperature, injection speed and injection pressure, molding cycle, etc.).


gas injection molding process5.jpegPlasticizing pressure: (back pressure) using screw type injection machine, the screw top melting material in the screw back when the pressure is called the plasticizing pressure, also known as back pressure. The magnitude of this pressure can be adjusted by the relief valve in the hydraulic system. After the injection, plastic pressure is with screw design, product quality requirements and different kinds of plastics and need to change, if these conditions and screw speed are constant, increase the plasticization pressure will enhance the shearing action, which will increase the melt temperature, but decrease the plasticizing efficiency, increase countercurrent and the leakage current, increase drive power.
