Release time:
2023-12-12
We often encounter many defective products in our life, such as buying a piece of clothing with poor stitching and a lot of thread ends. In the production and manufacturing process of plastic logistics boxes, it is inevitable that there will be some defective products with unqualified quality.
Today, I will tell you some common places where the quality is not up to standard in the production process. We should pay attention to it when purchasing.
1. Injection molding is short of materials. This phenomenon may be caused by the fact that the screw position is not adjusted accurately at the beginning of the plastic logistics box mold test, or by the low melt temperature, the insufficient mold temperature, or the low secondary injection pressure and rate. It is enough to make corresponding adjustments to these two situations. Of course, for the closed vacuum type feeding machine, it is necessary to confirm whether the raw materials are sufficient.
