Mainly due to mechanical polishing done manually Caizhuan plastic mold, so the impact is still the main reason for polishing polishing quality. In addition, also with mold material, surface condition before polishing, heat treatment process and so on. Quality steel is polished to get a good quality prerequisite, if uneven surface hardness of steel or the characteristic differences tend to produce polished difficult. Steel various inclusions and pores are not conducive to polishing. Effect of different hardness on the polishing process, the hardness increased to make difficult the grinding is increased, but the roughness after polishing decreases. Due to increased hardness Caizhuan small strip of plastic molds, polishing time to achieve the required low roughness corresponding growth. Meanwhile hardness increased, a corresponding reduction in the likelihood of over-polishing.
