Graphite electrode is usually used as extruded graphite materials, because of low resistivity of extruded graphite, conductive performance is good, the price is competitive Mold geometry increasing complexity and diversification of product applications has led to the discharge of sparks getting high accuracy requirements. Graphite electrodes are the advantages of easier machining, electrical discharge machining removal rate is high, small graphite loss, therefore, part of the group of sparks machine customers gave up and switched to the copper electrode graphite electrodes. In addition, some special shape of the electrodes can not be made of copper, but are more easily molded graphite and copper electrodes heavy, not suitable for processing large electrode, these factors have caused some group of sparks machine…
Graphite Tubes are mainly used in the industries , and according to the production procedure difference , it can be divied into two major kinds , one is machined by the pure graphite material , such as the isostatic graphite material , moulded graphite material , extruded graphite material and vibracation graphite material , machining from the raw material in the machine . the other kind is pressed directly by moulds. Graphite Tubes and are widely used in the Tooling (EDM), Mould Making (EDM), and General Manufacturing industries. Graphite Tubes are typically used in roughing EDM applications. They can also be used as flux tubes in the high temperature sintering industry. We are engaged in manufacturing a wide range of…
Carbon felt is made up of carbon fiber and felt like,it divided into two categories,classificated by raw materials. RAYON and PAN. Carbon felt has the properities as the bulk graphite,such as: high temperature resistance,corrosion resistance,non melting etc.meanwhile,it’s also low density,flexible, elastic, collapsible, clipping, suture as the fiber. Carbon felt is widely used as the high temperature heat insulation material for high temperature furnace(eg.high temperature carbon tube furnace), high temperature induction furnace and vacuum coating furnace.as it has a low invasion with molten metal,ceramic and glass etc.so it could be used as a surface coverings of these material,to reduce the heat loss.The fiber in the carbon felt whose diameter is less than 10μm,so it’s also good using as catalyst carrier. The…
