Common problems and causes of sheet metal fabrication processing stamping parts processing

1. Glitch: In the fabrication process of punching or trimming, the residual material is not completely left, and the burr is generated under the section of the steel plate. Based on the cross-section, when the burr height is 0.2mm or more, the iron powder will damage the mold and cause unevenness. . 
2. Concave and concave: The Surface of the material is abnormally raised or sunken, which is caused by the incorporation of foreign matter (iron filings, dust) on the unwinding line. 
3. Roller printing: The cleaning roller or the feeding roller is caused by the attachment of foreign matter (occurring at a fixed pitch). Under normal circumstances, the foreign matter printed on the sheet can be removed. 
4. Sliding print: occurs when the roller slides, when it stops suddenly or accelerates. 
5. The pulverization of the coil may be creeping at the edge: the guide roller of the unwinding line may be caused by the wrinkling of the gap between the guide rollers on the mold, which is caused by the unwinding of the coil feed.
6. Scratches: The main cause of scratches on the parts. There are sharp scratches on the mold or metal dust falling into the mold. Preventing measures is to repair the scratches on the mold and remove metal dust. 
7. Bottom cracking: The main reason for cracking at the bottom of the part is that the material is poorly plasticized or the die presser ring is pressed too tightly. The prevention measures are to replace the plastic material or to loosen the presser ring. 
8. Wrinkles on the side wall: The main reason for wrinkles on the side wall of the part is that the thickness of the material is insufficient (slightly small thickness is allowed to be thin) or eccentricity occurs when the upper and lower molds are installed, resulting in a large gap on one side and a small gap on the other side. Preventive measures are to replace materials and re-adjust the mold.
