        Injection mold is one of the important technology and equipment, production of various industrial products with the rapid development of plastic industry, as well as plastic products in aviation, aerospace, electronics, machinery, shipbuilding and automobile industries, products is becoming more and more high to the requirement of the mould, the traditional mould design method has been unable to adapt to today's requirements. Compared with the traditional mould design, computer aided engineering (CAE) technology both in terms of improve productivity, ensure the quality of products, or in terms of reduce cost, reduce labor intensity, has great superiority.

        In injection mold processing, all kinds of nc machining are useful to apply the most is the numerical control milling and processing center, CNC wire cutting processing and the application of the numerical control electric spark machining in the mold nc machining is also very common, line is mainly used in all kinds of straight wall mould processing, such as stamping concave and convex die, in the process of injection mold of the set piece, slider, edm work electrode, etc. For the mold parts with high hardness, machining method can not be used, mostly using EDM, in addition for the mold cavity sharp Angle, deep cavity parts, narrow slot, etc. Also use EDM. And CNC lathe is mainly used for processing standard parts of mold rod, and rotary mold cavity or core, such as the injection mold of bottle body, basin, shaft, disk parts of the forging die. The application of NC drilling machine can also improve the machining precision and shorten the machining cycle.

        Moulds are widely used in the modern manufacturing industry. Almost all parts of products are processed by moulds. Therefore, the mold industry is an important part of the national high-tech industry, is an important and valuable technical resources. Optimize the structure design of mould system and CAD/CAE/CAM of mould parts, and make it more intelligent, improve the forming processing technology and mould standardization level of mould parts, improve the precision and quality of mould manufacturing, reduce the grinding and polishing operation amount and manufacturing cycle of mould parts; Research and application of high performance, free cutting materials for various kinds of mold parts to improve the performance of the mold; In order to adapt to the diversification of the market and the trial production of new products, the application of rapid prototyping manufacturing technology and rapid prototyping technology, to rapidly manufacture molding punch, plastic injection mold or die casting mold, etc., should be the next 5 to 20 years of mold production technology development trend.
