Many companies often need to purchase plastic logistics boxes, plastic turnover boxes and other logistics equipment in batches. When checking and accepting the goods, you will definitely check the quality of the plastic boxes. The following will teach you how to find the common aspects of quality that are not good.
1. Distorted and deformed. Distorted plastic boxes are obviously unqualified. The main reason for this is that the cooling time is too short and the mold temperature is too high.
2. Uneven color. It is easy to find this problem by carefully observing the surface of the plastic box. The main reason for this situation is that the barrel is stagnant too long, the mold has a dead corner, and the plasticization is uneven.
3. There are wrinkles on the surface. Wrinkles on the smooth surface of the plastic box are obvious. The main reason for this is that the mold is too large and the material flows through the front end to cool down too early.
