Description of works
injection product
tion product At present,dimensional precision of common plastic parts is required to IT6-7,surface roughness Ra0.2-0.1mm.Dimensional precision of matching plastic injection mold parts is required to reach IT5-6,and surface roughness should be below than Ra0.1mm. Roughness of laser disc recording suinjection productrface 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 45# steels may be used,i.e. creating a cavity directly in the mold base. injection tool The acid base ratio
