The application of graphite electrode effectively improve the efficiency of plastic mould processing and manufacturing

Product updates faster and faster, demand more and more short development cycle, plastic mold manufacturing cycle is greatly compressed, how to improve the efficiency of mould manufacturing is a very important subject. Well-known edm when plastic mould manufacturing in the most time consuming, the most important, the most precise and final machining process. In Germany, the United States and Japan and other developed countries in plastic mould making, commonly used graphite electrode to replace copper, so as to greatly improve processing efficiency, thanks to the milling graphite electrode and graphite edm can get as much as several times of efficiency, let's together to summarize graphite electrode which has much more advantages than copper electrode: 1) Processing: graphite due to its high efficiency is only about 1/5 of the metal cutting resistance, thus the machining efficiency depending on the different shapes of 2 ~ 5 times that of copper electrode; Electro discharge machining efficiency difference, depending on the electrode size and shape are also about 2 ~ 3 times higher than copper electrode; 2) Material is not easy to deformation, easy machining thin steel electrode; 3) Light weight, the same volume of graphite materials, its weight is only 1/5 of the copper material, reduce the burden of machine tools; 4) Discharge loss is small, especially in the large area of the electrode discharge, attached to the electrode spark oil decomposition of carbide, will compensate the loss of electrode; 5) No burrs after graphite processing, eliminating the electrode work time and cost saving; And to make electrode processing automation application; 6) There are such as to caking property, easy polishing, etc. A lot of plastic mold factory boss will doubt, mould manufacturing, using graphite electrode to replace copper electrode discharge cost will increase? According to hon KaiYun experience in the use of plastic mould manufacturing can determine this confusion is unnecessary. Under normal circumstances, the use of graphite as the electrode material, the cost is lower rather than higher. Surface, copper electrode due to the advantages of recycling, might only with actual consume 60% of the volume of graphite electrode; But from the point of overall manufacturing costs, the graphite electrical extremely comprehensive cost must be reduced, and can save almost half of the manufacturing cycle, to win more orders for the enterprise, therefore, using graphite as electrode materials, can also enhance the overall competitiveness for mold enterprises. ISEM - graphite electrode vs. red copper electrode 8, this material can meet most of the auto parts plastic mold, household appliances plastic mould requirements, both the machining performance and discharge performance, at the same time is also very competitive in price, probably has the highest share of this field one of the material. High-end TTK - graphite material 4 be the first choice of the processing in recent years the horn net electrode material. We know that meet the personalized needs have become increasingly become one of the main means of differentiated competition, as car speaker speaker net mold, and shorter processing cycle, in the mesh electrode machining is often too late to customize graphite coated cutting tools, so the processing of mesh cutting tool is often temporary customization of ordinary tungsten steel cutter, easy to wear; This requires graphite material hardness is moderate, but when in edm loss and are small enough, TTK - 4 has these advantages. In addition, the Shanghai market there have been some new mixture of graphite and copper material, mainly used in connectors precision plastic mould and special aviation mold domain, in the processing of 0. 1 to 0. When a 2 mm thin steel is not easy, like graphite prone to collapse Angle, also won't like copper occur deformation. As the plastic mold is compressed more and more short development cycle, mould processing is still on the same processing way and sank the same unit price, plastic mold enterprise will have to close by to make ends meet. As a leader in plastic injection mold enterprise, we need to clearly recognize the present quantitative, variables, and incremental, completes the balance of payments, change itself to adapt to the current market environment, service more customers.
