【正文】 revolution made the new progress and the breakthrough unceasingly, the technical leap development already bees the important attribute which the impetus world economics grew. The market economy unceasing development, urges the industry product more and more to the multi varieties, high grade, the low cost direction to develop, in order to maintain and strengthens the product in market petitive power, product development cycle, production cycle more and more short, thereupon to makes each kind of product the essential craft equipment mold request to be more and more harsh. On the one hand the enterprise for the pursue scale benefit, causes the mold to turn towards high speed, is precise, the long life direction develops。 On the other hand enterprise in order to satisfy the multi varieties, the product renewal quickly, wins the market the need, requests the mold to turn towards the manufacture cycle to be short, the cost low fast economy direction develops. The puter, the laser, electronic, the new material, the new technical development, causes the fast economical pattern making technology even more powerful, the application scope expands unceasingly, the type increases unceasingly, the creation economic efficiency and the social efficiency are more and more remarkable. The fast economical pattern making technology and the traditional machinefinishing pares, has the pattern making cycle short, the cost is low, the precision and the life can satisfy in the production the operation requirements, is synthesizes an economic efficiency quite remarkable kind to make the mold the technology, summarizes below, has several types to leave. 1 fast prototypes manufactures technology The fast prototype manufacture technology is called RPM, is one kind of new manufacture technology which the 8039。s later period develops. US, Japan, England, Israel, Germany, China have all promoted own mercialization product, and has formed the new industry is the puter, the laser, the optical scanning, the advanced new material, the puteraided design (CAD), the puter assistance processing (CAM), the numerical control (CNC) synthesizes the application the high technology and new technology. In takes shape in the concept take the plane separate, piles up as the instruction, in the control take the puter and the numerical control as the foundation, take biggest flexibility as general goals. It has abandoned the traditional machinefinishing method, to the manufacturing industry transformation is a significant breakthrough, uses the RPM technology to be possible directly or indirectly the fast pattern making, this technology already by profession widespread application and so on automobile, aviation, electrical appliances, ships, medical service, mold. 2 surfaces take shape the pattern making technology The surface takes shape the pattern making technology, mainly is the use spurts spreads, the electrolytic casting, chemistry corrosion and so on the new technique formation cavity surface and the fine pattern one kind of craft technology, in the practical application including following several kind of types. electric arcs spurt spread take shape the pattern making technology The electric arc spurts spreads takes shape the technical principle is: Has the electric arc quantity of heat using between 2 circular telegrams tinsel to melt the tinsel, depends upon 7 the pressed gas its full atomization, and gives the certain kiic energy, high speed sprays in the type mold surface, layer upon layer mounts, forms a metal shell, namely the cavity internal surface, uses to fill the substrate material again (generally for metal silt and resin pound materials) performs to support the reinforcement, enhances its intensity and the rigidity, bines the mold together with the metal pattern frame.
