Injection
mold construction is the process of creating molds that are used to perform
injection molding operations using an injection molding machine. These are
generally used to produce plastic parts using a core and a cavity.
Molds are
designed as two-plate or three-plate molds, depending on the type of component
to be manufactured. The two plate mold requires a single day in light, while
the three plate mold requires two days. Mold construction depends on the shape
of the component, which determines the parting line selection, runner and gate
selection and component ejection system selection. The mold base size depends
on component size and number of cavities to be planned per mold.
