Which materials can uses for mold surface sandblasting, mold texture and mold atomization treatment
White corundum is used for sandblasting on the mold surface, mold texturing, mold atomization treatment and other processing operations.
White corundum is made of high-quality aluminum oxide powder as raw material and is smelted at a high temperature of more than 2,000 degrees. It has high purity, good self-sharpening, acid and alkali corrosion resistance, high temperature resistance, and stable thermal performance. Its hardness is slightly higher than that of brown corundum, and its toughness is slightly lower. It has strong grinding ability, low heat generation, and high efficiency. It has high hardness, dense particles, good roundness of single particles, pure white color, and no impurities. It ensures the color and transparency of the wear-resistant layer or wear-resistant paper, uniform and concentrated particle size distribution, and consistent shape of single particles. The maximum wear-resistant effect can be achieved with the least amount. Therefore, white corundum is usually used as the preferred abrasive for sandblasting on the mold surface, atomization treatment after mold texturing, wire cutting mold, artistic processing of craft glass patterns, atomization treatment, tire molds, conductive rubber molds, various shoe molds, electroplating molds, plastic product molds, etc.
