Expain 3 shot injection molding process
In injection blow molding starting parison is injection molded rather than extruded. In extrusion " " extrusion of parison occurs. There is three steps in injection blow molding: injection, parison and ejection. Tooling cost is higher in injection blow molding. one more, hot knife cut off the resins coming from heating zones before these goes to mold.

Shot Capacity : The maximum weight of molten resin that the injection molding machine can push out with one forward stroke of the screw during injection molding operation. Shot weight : The weight of the material injected into the mold in a single shot by an injection molding machine. (Weight of the molded part(s) + Weight of the runner + gate and the sprue)
Ceramic injection molding is similar to plastic molding. It uses a machine that heats ceramic at a very high temperature. It will melt it than it will heat it to make it stay.
It is made from different types of metal
