【正文】 ave mold with the small strength one kind of fast economical pattern making technology. Ultra models takes shape material typical representative is Zn22%AL. 5 does not have the mold multi spots forming technology Does not have the mold multi spots fast forming technology is by CAD/CAM/CAT The technology is the main method about, may adjust the base main body group highly using the puter control to form forms the surface, replaces the traditional mold to carry on the three dimensional curved surface forming to the sheet an modern advanced manufacture technology. This technology may change the distortion way and the stressful condition at will, enhances the material the formed limit, may form repeatedly, by this elimination material interior remaining stress, the realization does not have 4 the snapping back forming 6 triumphant Uygur bright steel belt blanking falls the material pattern making technology The new steel belt blanking falls the material pattern making technology is one kind is different with has raised, the concave mold structure steel belt mold generally, it is with specially makes the new fast economical pattern making technology by the single edge steel belt which the backing strip is posed. This kind of mold weight is light, only then 200kg, the processing precision for 177。 1 Modern fast economy manufacture mold technology Along with the global economy development, the new technological 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。, may suit each kind of black and the nonferrous metal thick sheet processing generally. The life may achieve 525 ten thousand, the production cost is low. 7 molds semifinished materials fast manufacture technology solid casting Because the massive molds are belong to the single unit or the production, the mold semifinished materials manufacture quality and the cycle and the cost to the final mold quality and cyclical and the cost influence are very important. The modern mold semifinished materials widely have used the seeds casting
