Our skilled machinists can make turned & milled parts using a wide range of plastic and metal materials.EDM / Wire EDM And Surface GrindingEDM (electrical discharge machining) is a method for cutting holes, pockets, and other shapes into hardened steel, as well as imparting a surface texture to the internal cavities of mold tools. A sacrificial electrode in an electrolyte bath discharges a high-powered electric spark to erode very hard materials that would be difficult or impossible to do with any other method. Square pocket holes are often created with this method.With wire EDM, a copper wire is continuously fed between two spools. When electrically charged, it’s able to cut through hardened tool steels quickly and accurately.At Sumitech, we also offer surface grinding services. When surface grinding the workpiece is held stationary on a horizontal plate. The surface grinding wheel is computer controlled to abrade the workpiece to a precise depth.Assembly LineWe also have assembly line to serving for Modular Assemblies and Custom Automation & System Integration.Our professional & international team of engineers and managers have combined advanced manufacturing technologies with traditional manufacturing techniques to provide you with a one stop shop for all your manufacturing needs.
