A pressure forming method and apparatus for use in an injection molding machine (10) for simultaneously performing the multiple functions of forming, cutting, and molding of deep-drawn injection molded pieces. The present method and apparatus of the invention eliminates individual loading of separate multiple pieces into the mold, saving loading time, reducing cycle time, and increasing through-put. The apparatus includes a forming tool having a first part and a second part for performing a forming operation on a substrate. The apparatus further includes an injection mold having a core part and a cavity part for performing a molding operation on the substrate after it has been formed in the forming tool. The apparatus places the forming tool on unused space within the injection molding machine (10), thereby utilizing the injection molding clamping pressure to closed the forming tool and seal the pressure chamber with the substrate held therein while a pressure medium is used to from the substrate in the forming tool. The apparatus results in a process which combines the three steps of forming, cutting, and injection molding a substrate into a continuous operation performed on an injection molding machine (10). |
