1. The material of the main working parts of the mold is not properly selected. The material has poor performance and is not wear-resistant; the die steel has not been refined and has a large number of smelting defects; the convex and concave die, the forging blank forging process is not perfect, and there are hidden dangers of heat treatment.
2. The design of the die structure is unreasonable. The slender punch is not designed with a reinforcement device, the discharge port is not well stacked, and the discharge force is too high. The ambassador punch is subject to increased alternating loads and so on.
3. The mold making process is imperfect, mainly manifested in the inherently poor quality of the male and female forging billets, and the heat treatment technology and process are problematic, causing the male and female molds to be hardly penetrated, with soft spots and uneven hardness. Sometimes micro-cracks, or even cracks, grinding and polishing are not in place, and the surface roughness value is too large.
4. No lubrication or lubrication but the effect is not good.
