Common problems and causes of precision metal stamping parts processing 'Hardware'

Many products in our daily life are metal stamping parts, and metal stamping parts need to be processed. However, we will encounter some common problems when processing precision metal stamping parts. The author of the metal stamping factory below Let me introduce to you the common problems and reasons in the processing of precision metal stamping parts. Common problems and reasons in the processing of precision metal stamping parts: 1. Burr: In the process of punching or trimming edges and corners, there is not completely leftover material, and burrs are generated under the section of the steel plate. Based on the section surface, when the burr height is 0.2mm or more , The generated iron powder will damage the mold and produce unevenness. 2. Concave and convex: The surface of the material is abnormally convex or concave, which is caused by foreign matter (iron filings, dust) in the uncoiling line. 3. Roller printing: it is caused by foreign matter attached to the cleaning roller or the feeding roller (occurred at a fixed pitch). Under normal circumstances, the foreign matter of the roller printing on the sheet can be removed. 4. Sliding mark: It is caused by the sliding of the roller and occurs when it stops or accelerates suddenly. 5. The roll material may be crushed or the edges may be wrinkled: the guide roller of the uncoiling line may be wrinkled when the guide roller gap on the mold is small, which is caused by the unbalanced feeding of the coil. The above is about some common problems in the processing of precision metal stamping parts. If you encounter the above situations, don't panic. They are all common problems. Pay attention to a lot of them during the processing and avoid them.
