Method of making plastic tooling with compression adjustment

摘要

A method of making a high load tool having a hard body of plastic material with compression plates on opposites sides to compress and strengthen the body. The method includes the steps of inserting passage forming pipes into a container and retaining the passage forming pipes in predetermined locations. Epoxy resin is poured into the container to cover the passage forming pipes and then the epoxy resin is cured. Elongated rods are inserted into the passage forming pipes and a pair of load spreader plates are placed at opposite ends of the elongated rods. Threaded bolts are advanced on at least one end of the elongated rods to move the spreader means towards one another and to compressively load the body.
