Tool Room & Mold Making
At GAP, our molds are built and engineered completely in-house allowing lower prices, faster turnaround, and a mold that best fit the customer's needs. Interfacing precision CNC and EDM machinery with the latest computer technology, the Mold Making Shop is at the forefront of modern die cast mold making.
We design 3D models of parts, molds and components. Engineering is also compatible with Pro Engineering, Auto Cad and all major 3D & 2D design software.
GAP will quote insert tooling. Their customers have the option of paying for inserts only and using company owned holders. By using these holders or mold bases this allows for faster lead times and lower costs.
EDM is a machining method primarily used for hard metals or those that would be impossible to machine with traditional techniques. One critical limitation, however, is that EDM only works with materials that are electrically conductive. EDM or Electrical Discharge Machining, is especially well-suited for cutting intricate contours or delicate cavities that would be difficult to produce with a grinder, an end mill or other cutting tools. Metals that can be machined with EDM include hastalloy, hardened tool-steel, titanium, carbide, inconel and kovar.
EDM or Electrical discharge machining is frequently used by us to make dies and molds for die casting. EDM, is especially well-suited for cutting thin ribs and other details that would be difficult to produce with a mill or other cutting tools. Often times with lighting die casting molds or die cast roof tile molds, intricate cuts are required. A graphite electrode must then be shaped and aligned in an EDM machine to produce the desired feature.
EDM is sometimes called "spark machining" because it removes metal by producing a rapid series of repetitive electrical discharges. These electrical discharges are passed between an electrode and the piece of metal being machined. The small amount of material that is removed from the workpiece is flushed away with a continuously flowing fluid. The repetitive discharges create a set of successively deeper craters in the work piece until the final shape is produced.
