【正文】 and so on automobile, airplane, mainly replaces the lumber or the metal manufacture automobile body host model, the profile, examines has and the casting model and so on. May process the plastic the main characteristic is has both the lumber and the metal fine workability, the manufacture craft simple and direct (may use pression molding, pour, spells sticks, method well and so on sculpture), the size stability, does not distort, bears moistly, anticorrosive, is easy to repair, the easy modification, the weight light, the manufacture cycle short, the cost to be low. Fast economical pattern making technology type very many, its has the characteristic, the application scope are various, this article only can broadly make some simple introductions, each kind of technology still had many concrete technological processes, the craft parameter and its the technical characteristic in the concrete application and the implementation 6 process. The mold is one of foundation industries, in the globalization market economy and under each kind of high technology and new technology swift and violent development situation, the fast economical mold has entrusted with the new mission and the brandnew connotation, the classification increases unceasingly, the fast economical pattern making material turns towards the multi varieties seriation to make great strides forward, the craft has the new innovation and the breakthrough unceasingly, is published one after another with it supplementary equipment, the service domain in opens up unceasingly, the creation economic efficiency is more and more remarkable. Along with the modity economy development, the intense market petition, the product renewal acceleration, is reducing the cycle to the fast economical pattern making technology, reduces the cost, will increase the precision and lengthens the life aspect the request to be able to be more and more high inevitably. Because it can cause the enterprise to win the market, creates the remarkable economic efficiency, more and more receives entrepreneur39。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 2 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 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 s
