rapid prototype
red to reach IT5-6,and surface roughness should be below than Ra0.1mm. Roughness of laser disc recording surface should reach to level of mirror finishing,0.02-0.01mm. So,the surface roughness of mold should be lower than 0.01mm. injection part For molds with extremely low requirements,S50C and 45rapid prototype# steels may be used,i.e. creating a cavity directly in the mold base. injection tool The acid base ratio,concentration,temperature and time of gelation are the specific process parameters of the gel granulation process.
