Cause Of Loss

  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 has not been refined and has a large number of smelting defects; the convex and concave molds, forging blanks and the forging process are not perfect, and there are hidden dangers of heat treatment.
  2. Die 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 piles up, and the discharge force is too large, and the punch is subjected to increased alternating load.
  3. The mold making process is imperfect, 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, causing the convex and concave molds to be incompletely quenched, with soft spots and uneven hardness. Sometimes microcracks or even cracks occur, 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.
