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, due to the unbalanced feeding of the coil Aroused related news: the characteristics of the main materials of stamping parts, the handling of common problems of stamping parts, the characteristics of scaffolding stamping parts and the importance of inspection, the advantages of metal stamping parts introduce the advantages, procedures and characteristics of stamping parts
