How To Solve The Orange Peel Phenomenon In Mould Surface
Sep 02, 2018

What is orange peel phenomenon, is the daily die polishing of the common problems in the process of polishing is excessive, is refers to the polishing, the longer the mould surface quality is poor, there are two kinds of polishing excessive occur: is the orange peel and pitting 

   So we wonder what causes this orange peel phenomenon? Caused overheating or carburizing mold surface, polishing pressure and polishing time is too long is the main cause of orange peel, concrete embodiment in the polishing of guide plate, the formation of pitting artifacts often make for hard and brittle oxide lead to is in the steel, so the causes of pitting corrosion is generally polishing pressure big, long, steel purity is not high, the mold surface rust, such as how to solve this problem? A. Carefully regrind the surface. The sand grain size is slightly larger than that previously used. When the size of the sand particle is less than 1mm, the softest polishing tool should be avoided. C. The shortest polishing time and the minimum polishing strength should be adopted as far as possible. A. remove defective surface, particle size of grinding use sand size slightly larger than the first level, grinding, polishing granularity lower b. below the temperature of the tempering temperature of 25 oc for stress, using the fine sand in front of the polishing, grinding, and finally to the lightest degree of polishing
