1. The material of the main working parts of the mold is improperly selected. The material has poor performance and is not wear-resistant; the die steel is unrefined and has a large number of smelting defects; the convex and concave die, the forging process of the forging blank is not perfect, and there are hidden dangers of heat treatment. We are a professional mold Parts manufacturer, all mold Parts are subject to strict quality control, welcome to cooperate with you
2. The mold structure design problem, the die structure is unreasonable. The slender punch is not designed with a reinforcement device, the discharge port is not smooth, and the stacking occurs.
3. The mold making process is not perfect, which is mainly manifested in the poor internal quality of the convex and concave die forging blanks, and the heat treatment technology and process have problems, resulting in the convex and concave molds not being quenched through, soft spots and uneven hardness. Sometimes micro-cracks or even cracking occur, grinding and polishing are not in place, and the surface roughness value is too large.
4. Unlubricated or lubricated but ineffective.
