In industrial production, we can often see injection molding. This method is generally suitable for rubber and plastic materials. The time of injection molding is affected in many ways. When the product structure is more complex, the processing difficulty will also increase. The volume will also have an impact on the processing time. Because the properties of different materials have certain differences, the processing time is different. Among them, what steps are included in the injection molding process of Shenzhen mold?

1. Heating materials

The transmission system drives the screw to work, transports and compacts the material in the hopper. The material gradually melts after the shear friction of the heater, screw and barrel outside the barrel. At this time, a certain amount of material has been accumulated in the head of the barrel. When the plastic is melted, the screw will retreat under the action of pressure, and will stop when the predetermined injection volume is reached.

2. Mold clamping and injection

In Shenzhen mold injection processing, mold clamping and locking operations should be carried out to ensure that sufficient clamping force can be provided. After the clamping and nozzle are fitted to the mold, the screw will push the melt into the cavity of the mold with sufficient pressure while maintaining The pressure inside the mold avoids the volume shrinkage caused by the temperature drop, and ensures the compactness, dimensional accuracy and mechanical properties of the product.

3. Pressure relief and mold opening

When the melt at the gate of the mold freezes, the pressure relief operation can be performed, otherwise the mold cannot be opened easily, and then the injection device is retracted to facilitate subsequent processing work. After the plastic part in the mold cavity is completely cooled and shaped, We need to use the clamping mechanism to open the mold and push out the plastic parts in the mold.

The above are the steps involved in Shenzhen mold injection processing. This method is simple and easy to operate. First, add the material to the mold, and then continuously rotate and heat along the vertical axis. After cooling and shaping, the corresponding workpiece can be obtained, and other Compared with the processing technology, it has the advantages of short cycle and low cost. It can be easily and quickly processed for workpieces with complex shapes. It is suitable for small batches and different shapes of production. The quality and structure of the workpieces are also guaranteed to a certain extent. The color can be changed at will according to customer requirements.
