EspañolOne of the common problems with plastic shopping basket: the product is cracked or broken.
In addition to excluding human damage, the main technical reasons for this situation are as follows:
The pressure of the injection molding machine is not enough when the pallet is produced. This problem is mainly because the performance of the injection molding machine itself is not up to standard, or the manufacturer has carried out overload injection molding. The most common example is to use a 5000-gram injection molding machine to inject large plastic pallet products. Obviously, the injection molding machine does not Such a large injection molding capacity, so it cannot meet the injection pressure index. The plastic pallet products produced will definitely have many new problems. It directly leads to cracks or even breaks in the plastic pallet products purchased by customers.
The melt flow rate is too fast during injection molding. This problem is mainly caused by the production speed being too fast. As a result, the gap joint of the mold cannot be well driven into the melt. This has caused lax bonding at the seams. Cracks may appear in the future.
The temperature of the barrel is too low, or the temperature of the mold is too low. Such problems are particularly easy to occur in winter. The main body is too cold due to the influence of the outside temperature, so that the molten material cannot be well filled into the mold cavity, and many unbonded materials appear. The area does have cracks in the plastic tray for future use....
