The main function of molds is to produce more consistent products, and the processing stability during the production process is an important factor to consider. Below, let's take a look at the common problems that stamping parts molds often encounter during the production process

(1) Adhesion and scratches: defects on the surface of a workpiece or mold caused by friction between the material and the convex or concave mold;

(2) Twist and strain: due to uneven stress, poor matching of stretching ribs, or poor control of the press slider, the corners or embossed parts of the workpiece undergo twists and strains;

(3) Wrinkles: Wrinkles on the edges or r areas caused by poor adjustment of the press slider, low precision of the press, improper adjustment of the air cushion pressure, large punch or r area, etc;

(4) Burr: It mainly occurs in shear molds and blanking molds, and the gap between the cutting edges may be large or small, resulting in burrs.

(5) Line offset: When forming a workpiece, the first part in contact with the mold is squeezed and forms a line;

(6) Convex and concave: foreign objects (iron filings, rubber, dust) mixed into the uncoiling line, causing convexity and concave; Www.ksdrum.com

In the production process, especially on the basis of not advanced technology and weak hardware conditions, problems are inevitable. However, we need to approach them with a scientific attitude and response strategies, so that problems can be easily solved.
