How to identify the advantages and disadvantages of incoming mold materials during mold design and processing?
A. Fake and inferior mold materials are easy to fold. Folds are various fold lines formed by the surface of the mold material, usually running through the entire length of the product. The reason for the folding is that the counterfeit and shoddy manufacturers pursue accuracy, and the pressing amount is too large, resulting in ears. The next rolling will produce folding, and the folded product will crack after bending, and the strength of the mold material will be greatly reduced.
B. The appearance of fake and inferior mold materials often has pockmarked surface. The pitted surface is the irregular unevenness on the surface of the incoming mold due to the serious wear of the rolling groove. Because the manufacturers of counterfeit and shoddy molds want to pursue profits, the rolling of the grooves often exceeds the standard.
C. Fake and inferior molds are prone to scarring on the surface of incoming materials.
1. The material of the fake and inferior mold is uneven and there are many impurities.
2. Fake and inferior materials have simple equipment and are easy to stick to steel. These impurities are prone to scarring after biting the roll.
D. The surface of the fake and inferior material is prone to cracks, because its blank is adobe, and the adobe has many pores, and the adobe is subjected to thermal stress during the cooling process, resulting in cracks. After rolling, there are cracks.
E. Fake and inferior mold materials are easy to be scratched, because the fake and inferior materials manufacturers have simple equipment, which is easy to produce burrs and scratch the surface of mold materials. Deep scratches reduce the strength of the incoming mold.
