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.
Claims6
A method of forming, cutting, and injection molding a printed stock in web form, the method comprising the steps of:
- forming a first portion of the printed stock within a forming portion of an injection molding machine;
- advancing the first portion of the printed stock after it has been formed into an injection molding portion of the injection molding machine and a second portion of the printed stock into the forming portion of the injection molding machine;
- injection molding the first portion of the printed stock and simultaneously cutting the first portion of the printed stock within the injection molding portion of the injection molding machine;
- and
- forming the second portion of the printed stock within the forming portion of the injection molding machine while simultaneously cutting and injection molding the first portion of the printed stock within the injection molding portion of the injection molding machine.
