Injection molding are batch production certain shapes complex components used by a kind of processing methods. Specific means that a heated melting material by high-pressure scored by cavity, cooling after curing, get forming products.

 

The injection molding process can be roughly divided into the following six stages of "shut the mould - injection - pressure-keeping - cool down - open mold - products take", the above process can be repeated, continuously produce products.

 

Injection molding machine injection molding machine can be divided into fits the mould device with an injection device. Shut the mould device main function is to realize mould opening and closing and ejection products. Shut the mould device can be divided into the long rod and using directly hydraulic exe  cutes shut the mould of direct pressure type.

Injection device is make resin material heated melts into the mould device. The resin boffins nitrogen-treated barrel, through screw rotation will melt transfer to the front end of the barrel. In the process, in heater under the effect of heating makes barrel within the resin material heated, in the screw of shear stress under the role that resin, will become molten state equivalent of molding product and mainstream way, way of molten resin shunt occluded in barrel front-end (called measurement), screw forward will materials into the cavity. When molten resin in the mould flow, must control screw movement speed (injection velocity), and in full of the cavity with resin pressure (pressure) the control. When screw position, injection pressure reaches a certain value when we can transmit speed control switch becomes pressure control.

Mould means, colophony material into metal model with certain shape after we get the products of the device. In fact in order to control the mould temperature, in the mold and make cold media (warm or oil) through the cooling hole, heater devices.
