the pressing of the electromagnetic coil is likely or will wrinkle along the edge: because the gap between the guide rollers on the mold is not large, the unwinding guide rollers are likely to wrinkle, which is also due to the imbalance of the electromagnetic coil caused by the feeding on the mold.

Scratches: The primary cause of scratches on parts. There are sharp scars on the mold or metal material soot falls into the mold. Zhejiang sheet metal processing factory told everyone that the preventive measures are to repair the scar on the mold and eliminate the smoke and dust of metal materials.

Wrinkles on the side wall: the first factor of wrinkles on the side wall of the part is insufficient material thickness (allowable smaller thickness) or eccentricity when assembling the upper mold and the lower mold, this in turn leads to great disadvantages at one side and at the bottom end. Nothing else makes much difference. The precaution is to disassemble the material and adjust the mould again immediately.
