Due to various adverse factors, the injection mold causes cracking of the drawn parts, which is a very serious appearance defect. Too many defective products or even complete scrapping greatly wastes raw materials and reduces production efficiency, wasting resource loss. How should such a situation be solved?

The coloring of the pressing surface is uneven and the polishing is poor, the pressing ribs are damaged, the length of the mold support is not the same after installation, and there are unreasonable places in the exhaust holes and drawing fillets. The above situations can be processed and repaired one by one.

The unreasonable position of the test punching sheet and the unreasonable air cushion pressure need to be adjusted within the appropriate range. At the same time, the flow and inflow of the sheet can be changed by padding gauze or other plastic cloth on the pressing surface.

Injection mold

The size and shape of the punching plate are unreasonable and there is no certain number of process holes. It can be improved by changing the size of the punching plate and adding process holes. Grid lines can also be printed on the test punching plate to know the situation of the sheet more clearly.

The profile in the direction of the material flow is relatively rough and needs to be polished. The fillet of the process supplement part can also be enlarged. In the subsequent process, there are fillets corresponding to the shaping and drawing dies, which can also be appropriately used. Just pay attention to the shaping amount and stamping direction.
