Injection Molding is a manufacturing process for producing parts in large volume. It is most typically used in mass-production processes where the same part is being created thousands or even millions of times in succession. Why Use Injection Molding: The principal advantage of injection molding is the ability to scale production en masse.

Slide locking block: It uses to assemble an angular pin and cavity plate. It will increase strength for the angular pin when mold closed. 4. Angular pin: This pin has draft angle from 10 deg ~25 deg.
Locking cylinders have a self contained locking mechanism that helps the cylinder hold against molding pressure. They are rated by pounds of holding pressure. This is calculated by multiplying the projected molding area on the slide by 10,000 psi. Spring actuated slide. Spring slides are usually not a good idea for plastic injection molds.
