Electrical discharge machining (EDM) is a controlled metal-removal process that is used to cut metal by means of electric spark erosion. In this process an electric spark is used as the cutting tool to cut (erode) the workpiece to produce the finished part to the desired shape. The part being machined have to be in the presence of a dielectric, ultra-pure water during the cutting and cooling process.

EDM/ Laser Cutting is widely applied in various industries, such as aviation, automotive, semiconductors and integrated electronics.

Our SM resin series products are designed to prepare ultra-pure water and condensed water treatment specifically for EDM, laser welding.

The products are ready-to-use resin comprising gel-type strong acid cation exchange resin and strong base anion exchange resin. Both components are mixed and compounded in accordance with specific chemical equivalents. Under the continuous and simultaneous exchange of anions and cations, high purity water can be easily obtained.
