  • Method of use of multi-purpose processing apparatus
    Patent number: 6730251
    Abstract: A method of using a multi-purpose processing apparatus for simultaneously performing an injection molding operation and a cutting/forming operation. The multi-purpose apparatus places a forming operation into unused space within the injection molding machine, thereby utilizing the already present injection molding clamping pressure to pressure form parts. The apparatus results in a method that combines the three steps of forming, cutting, and injection molding into one continuous operation performed within the injection molding machine, as well as eliminating the need for numerous pre-injection molding steps.
