Why does the processing of injection plastic parts produce deformation?

 

 

Such as plastic gears and electrical enclosure these products are widely used in our life, and also play an important role in our life. There are widely used in the machinery industry injection molding parts are also to carry out injection molding processing. Perhaps we will encounter deformation when we carry out injection molding, so this small series will simply talk to you about this problem.

 

 

 

1, for a long time or repeated application of stress below the mechanical properties of plastic parts caused by external or internal crack scene called stress cracking; Because the plastic parts at a specific temperature to taste the stability of the moment of the load effect and suddenly complete crack scene called stress crack; Thermal stress cracking occurs when some thermoplastic parts are overexposed to high temperature. So the temperature needs to be well controlled.

 

2, material processing because of the improper flow of melt in the mold cavity, resulting in the plastic surface and the occurrence of ring-like, spiral or cloud-like waveform uneven shortcomings. The appearance of plastic processing plastic parts has open space cracks and the resulting damage. If the processed products are damaged, such products cannot be used normally.

 

It is mainly to take you to understand the two main reasons for the deformation of plastic parts. After reading the content of this article, you will know more about injection molding parts. If you are interested, you can pay attention to our official website dynamics, we will continue to update oh!
