The characteristics of the coating determine their mechanical properties are different?


For any coated products of automobile molds, their mechanical properties are different due to the characteristics of the coating.




A simple summary: 1 the level of the surface hardness of the coating,




2 The bonding force between the coating and the substrate, that is, the peel resistance.




3 High temperature resistance of the coating




4 Corrosion resistance of the coating




5Under normal process, the maximum thickness that the coating can be formed. If the wear is uniform, theoretically, the thicker the coating thickness of the automobile mold, the longer the service life; however, because the coating generally has a higher hardness, the thicker the coating, the easier it is to collapse.




Cost-effectiveness of 6 coatings




7The influence of coating production process on the deformation of the mold.




8 Stability of the production process. Most of the molds cannot be produced before they are re-coated and processed. They have to be in a hurry and have no time to rework. Therefore, the actual requirements for the stability of the coating production process are very high. But it is often ignored.




9 Sliding friction coefficient and smoothness of the coating surface




10The same mold material, the number of times the coating can be applied repeatedly, etc.




If a coating for automotive molds has all the advantages, it is the final coating. However, in fact it has not yet appeared, so we can only choose the coating with the most advantages according to our own product characteristics to meet our own production and processing needs.
