The injection process related parameters of abs injection mold mainly include drying of ABS material, injection temperature, injection pressure, injection speed, mold temperature, material quantity control, etc. Let's analyze the injection process related parameters of abs injection mold in detail.
1. Drying of ABS material
The presence of water vapor will cause fog spots, bubbles, and silver wires on the surface of the workpiece. Therefore, it must be fully dried and preheated before processing. It is best to convert the hopper of the machine into a hot air hopper.
2. Injection temperature
The suitable temperature range for ABS plastic processing is 220-250 °C. Due to the high processing temperature of ABS, it is very sensitive to changes in various process factors, so it is not possible to blindly increase the temperature. The temperature control of the front end of the barrel and the nozzle part is very important.
3. Injection pressure
ABS generally uses higher injection pressure, and individual uses low-pressure injection, such as small size and simple structure. Thick parts can be injected with low pressure. Injection that is too large or too small will have a bad effect on the quality of the plastic.
4. Injection speed
ABS materials generally use a medium injection speed, and a sufficiently high injection speed must be ensured when producing thin-walled or complex parts. The specific analysis of the injection speed should be based on the actual situation of processing.
ABS plastic is widely used, and it has the characteristics of impact resistance, heat resistance, low temperature resistance, etc. The injection process and mold design of domestic abs injection molds are becoming more and more mature, which will further promote the development of ABS plastic products.
