Hardware accessories in advance the main reason for the permanent failure?
Time:2017-12-14 9:55:07  Browse:

Generally speaking, the hardware parts we make will be designed and made according to the actual situation. But after a period of use, the mold will appear early in error or permanent failure. Today we will answer this question by JinJue Hardware Xiaobian.

1) The main parts of the mold material problems, improper material selection. Material performance is not good, not wear-resistant; die steel without refining, with a large number of smelting defects; punch, forging billet forging process is imperfect, there are still hidden heat treatment.

2) mold design problems, stamping die structure is unreasonable. Slender punch is not designed to strengthen the device, the discharge port unlucky pile, unloading force Ambassador to withstand alternating alternating convex load and so on.

3) imperfect molding process, mainly in the convex, die-forged billet inherent poor quality, heat treatment technology and process problems, resulting in convex, die quenching impermeable, soft spots and uneven hardness. Sometimes produce microcracks, or even cracking, grinding and polishing is not in place, the surface roughness value is too large.

4) No lubrication or lubrication but the effect is not good.
