<p>A first aspect of the invention relates to the manufacture of disparate workpieces by the process of injection molding using a single base tool. The tool is made up of cavity and core halves, and each half is made up of separate, removable/interchangeable, inserts which, when combined in a particular order, form the workpiece-forming surface. All or any number of the inserts may be replaced with other inserts to alter the workpiece-forming surface and allow a large number of differently shaped workpieces (i.e. having different surface features and shapes) to be formed from a single base tool. In another aspect of the invention, the inserts are connected to respective thermally conductive cavity and core mounting plates, which are in turn connected to respective cavity and core heating/cooling plates so that insert-mounting holes need not be made in the heating/cooling plates.</p> |
