injection tooling
ype By specifying the opening length and width,a draft angle,and a depth,it is not necessary to specify the dimensions for the internal surface,as these may be calculated from the above. prototype Therefore,many industrially developed countries have created an extensive range of plastic mold steeinjection toolingl series,including carbon steel,carburized plastic mold steel,aging hardening plastic mold steel,corrosion resistant plastic mold steel,free machining plastic mold steel,through-hardening plastic mold steel,maraging plastic mold steel and mirror polishing plastic mold steel,etc. prototype aluminium
