Generally speaking, we made the hardware parts will be based on the actual situation of the design and production, but after a period of time, the mold will be ahead of the error or permanent failure, today by the Gold Jazz hardware Xiaobian to answer this question for everyone.

1) mold the main working parts of the material problems, improper selection. Material performance is bad, not wear; mold steel without refining, with a large number of smelting defects; convex and concave die, forging forging process is not perfect, there are hidden heat treatment hidden.

2) mold structure design problems, stamping die structure is unreasonable. Slender punch is not designed to reinforce the device, the discharge port appears poor accumulation, unloading force over the ambassador to bear the alternating load intensified.

3) Modification process is not perfect, mainly in the convex, concave die forging quality is poor, heat treatment technology and technology problems, resulting in convex, die quenching, soft and uneven hardness. Sometimes produce micro-cracks, and even cracking, grinding and polishing is not in place, the surface roughness value is too large.

4) No lubrication or lubrication but poor effect.
