What are the considerations when processing plastic molds?


1. The injection temperature is not high enough. In the design and processing of plastic molds, the mold temperature must be controlled. General plastic materials strictly limit the processing temperature, the heating temperature should not exceed 150 ℃, otherwise, the material will be deformed, or even deteriorate.

2. Fast injection speed. When we inject some plastic products, if the injection speed is very slow or terminated, it will lead to deformation of the molded products and then cause damage to the products. Therefore, we should not be impatient in the processing process. The product processing process should not be too long, and the cooling time is enough for the cooling time.

3. The temperature of the mold is not high enough. Whether the mold temperature is high enough is also related to the melting level. Generally speaking, the higher the temperature, the worse the circulation and plasticity of the plastic. In this case, it is necessary to ease the heating rate of the mold or moderately advance the cooling time of the mold.

4. The pressure of the plastic machine is too high. When we use high pressure plastic machine, there will be some problems, such as dents in the mold, after all, under high pressure conditions, the mold is relatively less elastic and prone to this situation.

5. Mold heating device failure. When the mold heating device fails, the mold temperature control is not accurate. In this case, the mold heating pipe should be checked in time to see if the pipe is broken and the joint is firmly connected.

6. Injecting speed is not adjusted properly. Too fast adjustment of injection speed will lead to too much plastic compaction in the mold, resulting in shrinkage or bubbles.

Well, the above is a little knowledge about plastic molds, I hope it can be helpful to you ~
