Mold design is the analysis, design, and refinement of molds for industrial manufacturing. Molds must be able to form the solid part out of the molten material, cool the part so it can solidify, and eject the part from the mold. The list of ways in which a mold can fail to accomplish these purposes is long and vivid.
The Types of Plastic Molding
The most popular techniques in plastic molding are rotational molding, injection molding, blow molding, compression molding, extrusion molding, and thermoforming.
A three-plate mold is used when part of the runner system is on a different plane to the injection location. The runner system for a three-plate mold sits on a second parting plane parallel to the main parting plane.
This technique includes at least four different methods: permanent, die, centrifugal, and continuous casting.
