Mirror polished mold surface engineering skills

Mold polishing skills is an important part of the mold surface engineering, mold manufacturing process is an important post-processing technology. Now, domestic polishing to Ra0.05μm polishing equipment, abrasive abrasive and technology, to meet the needs of the fundamental, but to throw Ra0.025μm mirror polishing equipment, abrasive abrasive and technology is still at the exploratory stage. With the large-scale use of mirror injection mold in production, mold polishing skills have become the key issue of mold production. Because of the domestic polishing process skills and information, there are still some problems, so as a fool camera lens injection mold, CD, VCD disc and transparency of plastic injection mold still have a large part of the need to rely on imports.

It is noteworthy that the mold surface polishing is not only affected by the polishing equipment and process skills, but also by the mirror material degree of influence, which has not attracted enough attention, that is, polishing itself by the mold data constraints. For example, with 45 # carbon steel injection mold, polished to Ra0.2μm, the naked eye can see significant shortcomings, continue to throw away only add brightness, and the roughness has been no hope of improvement, it is now produced in the mirror mold Often use imported mold information, such as Sweden, one hundred win 136, Japan's Datong PD555 and so can meet the mirror.

Mirror mold information is not only a chemical composition of the problem, the more important is the choice of smelting vacuum degassing, argon maintenance ingot, vertical continuous casting and rolling, soft forging and a series of advanced technology so that the mirror mold steel with fewer internal shortcomings, Impurities, fine grain size, high degree of dispersion, the fine grain size, good uniformity and a series of strengths, in order to achieve the requirements of polished steel to the mirror surface.
