soft tooling
n moulds Design parts to facilitate easy withdrawal from the mold by providing draft (taper) in the direction of mold opening or closing. rubber injection It is purchased as a two-part raw material with a grease-like viscosity. injection product At present,dimensional precision of common plastisoft toolingc 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 surface should reach to level of mirror finishing,0.02-0.01mm. So
