Plastic gears, electrical enclosures and other products are widely used in our lives and play an important role in our lives. For example, many plastic products used in our lives require plastic processing in Changzhou, and injection molding products widely used in the machinery industry also need processing. Maybe everyone will encounter deformation when processing injection molded parts, so this time I will briefly talk about this problem with you.
1. The phenomenon of cracks on the outside or inside of plastic parts due to long-term or repeated application of stress lower than the mechanical properties of plastics is called stress cracking; because plastic parts are suddenly and completely broken due to a stable load at a certain temperature at a certain time This phenomenon is called stress cracking; the cracks and fractures that occur when certain thermoplastic parts are overexposed to higher temperatures are called thermal stress cracking. Therefore, the temperature needs to be well controlled.
2. Due to the improper flow of the melt in the mold cavity, the plastic parts have irregular defects in the shape of annual rings, spirals or clouds. Plastic processing There are cracks on the surface of plastic parts and the resulting damage. If the processed product is damaged, the product cannot be used normally.

Parts that are prone to shrinkage during injection molding
When plastic parts are injection-molded, the injection-molded parts may shrink or shrink locally due to various factors. For precision injection molded parts, it will seriously cause the injection molded parts to be scrapped. Where are the parts that are prone to shrinkage during injection molding in the injection molding factory?
