Structure of Molds

You will learn about two-plate molds, three-plate molds and runnerless molds in this chapter.

The basic structure of a mold is determined by restrictions such as selections of molding shape, production quantity, molding material, or gate position, as well as productive and technical considerations. The structure of a mold is categorized into a two-plate (two-structured) mold, a three-plate (three-tructured) mold, a runnerless mold, and a special mold, each of which has special characteristics.
