How to reduce the defects of PC plastic products?
Release time:
2025-08-02
First, improve the cooling conditions in the grinding process of PC injection molding process, such as the use of immersion grinding wheel or internal cold grinding wheel and other measures. We can use the characteristics of the cutting fluid, its introduction into the grinding area, this operation can achieve a good cooling effect, and can ensure that the surface of the PC plastic products will not appear damage damage.
Second, the quenching stress after heat treatment is reduced to a very small, because the stress caused by quenching as well as in the network of carbonized tissue constantly grinding force to promote the role of the internal organization of the PC plastic products will become very fragile, and at this time, if we operate a little bit of deviation is very easy to produce surface cracks.
Third, in order to eliminate grinding stress, PC plastic products can also be in 260-315 ℃ salt bath immersion 1.5min, and then cooled in 30 ℃ oil, so that the hardness is reduced by 1hrc, the residual stress is reduced by 40% -65%.
Fourth, for the size of the sometimes occurring tolerances of less than 0.01mm PC plastic products, we need to carry out precision grinding processing, grinding must pay attention to the ambient temperature at that time, the ambient temperature of the PC plastic products is also the influence of the subtle, if it is determined that there is no error can be carried out under the circumstance of constant temperature grinding.
Fifth, in order to improve the manufacturing precision and surface quality of PC plastic products, we can also utilize the role of electrolytic grinding operation.
