Due to various adverse factors, the extruded parts produced by the injection mold have cracks, which is a very serious appearance defect. Excessive defective products may even be completely scrapped, causing a significant waste of raw materials and reducing production efficiency, as well as wasting resources and causing losses. How should such a situation be resolved? 

The surface of the die-pressing area is unevenly colored and has poor gloss. The die-pressing ribs are damaged. The mold support is installed in an uneven manner, and the lengths of the exhaust holes and the draw ring corners are not consistent. There are unreasonable aspects in the exhaust holes and the draw ring corners. The above issues can be addressed and corrected one by one. 

The incorrect position of the test plate and the unreasonable air cushion pressure need to be adjusted within an appropriate range. At the same time, methods such as placing gauze or other plastic sheets on the die surface can be used to change the flow and inflow of the plate.

The size and shape of the blanking plate are unreasonable and there are not enough processing holes. These can be improved by changing the size of the blanking plate and adding more processing holes. Additionally, grid lines can be printed on the test blanking plate to better understand the condition of the sheet material. 

The surface of the material flow direction is relatively rough and requires polishing. Alternatively, the rounded corners of the supplementary part of the process can be enlarged. In the subsequent processes, the rounded corners corresponding to the forming and drawing dies can also be appropriately processed using certain methods, but it is necessary to pay attention to the forming amount and the direction of the stamping.
