Stamping is one of the practical processes for producing large quantities of parts. Die failure is the most common problem in stamping production, often resulting in shutdown, affecting the product cycle. Therefore, it is necessary to find the cause of mold failure as soon as possible and make reasonable maintenance.

1 die damage
Die damage refers to the mold cracking, breaking, rising and so on, dealing with mold damage problems, it must be from the mold design, manufacturing processes and the use of mold to find reasons.

2 clamping die
The main reasons causing mould clamping are: the die guide is incorrect and inclined. Otherwise, the fault will be enlarged and the die will be damaged.

3 die damage and maintenance
When the die repair technology is too complex and the cost of mould repair is too large and difficult, the maintenance cycle will be too long, and the normal production of stamping will be seriously affected. Generally speaking.

Timely maintenance of the mold to prevent damage to the mold can greatly reduce the cost of stamping mold production. When the pivot parts of the die are severely damaged, sometimes the convex and concave dies are damaged at the same time.

Under normal circumstances, the main failure mode of stamping is excessive wear. Deliver from new mold manufacturing. Until the burrs of the stamping parts exceed the standard, the parts size and the shape and position accuracy are too bad, and the mold can not be repaired or not repaired at all, the die can only be scrapped. From the new mold into use until the failure of scrap.
