The quality of metal molds includes the following aspects:
(1) Product quality: the stability and conformity of product dimensions, the surface finish of the product, the utilization rate of product materials, etc.;
(2) Service life: on the premise of ensuring product quality, the number of work cycles that the mold can complete or the number of parts produced;
(3) Use and maintenance of the mold: whether it is more convenient to use, easy to demould, and the auxiliary production time is as short as possible;
⑷ maintenance costs, maintenance periodicity and so on.

Appropriate way to protect hardware drawing die equipment.
The protection and maintenance of the drawing die as required is beneficial to extend the service life of the equipment and improve the working efficiency of the equipment. Picking a reliable trader not only has obvious advantages, but also a reasonable price. Also, better products will be in place in the after sales service, which really helps a lot. After all, choosing a scientific approach will be more reassuring and more attentive in service. Therefore, a reasonable choice will be more conducive for people to bear it.

Advantages of metal stamping parts.
1. The standard and shape accuracy of metal stamping parts are generally not damaged by the surface quality of the stamping parts through the mold, so the life of the mold is longer, so the quality of the metal stamping parts is stable.
2. Metal stamping can process parts with large standards and messy shapes, as small as stopwatches, as large as longitudinal beams of cars, parts, etc., plus the cold deformation hardening effect of metal stamping, the strength and rigidity of metal stamping are relatively high.
