ity peace. zinc metal alloy system mold technique This is a kind of to take the kind piece( or the kind mold) as the basis, with the order for 380 ℃ s or so zinc metal alloys for material, sprinkle to note the convex and cave mold respectively, a surface does not carry on one kind system mold technique that the machine process in technique39。 s characteristics is to make the mold cost low, the period is short, being applicable to create the lamella large pull to stretch the mold and hurtle to cut the mold and plastics molds. resin pounds model the molding tool technique This is a kind of to take the kind mold( or the craft model) as the basis, taking resin or its pound materials as the fluid material, sprinkling the convex( cave) mold of outpouring first, again the convex( cave) mold of basis sticks up the wax slice( the cleft layer), sprinkling to note the convex( cave) surface that that technique model does not need the machine to that technique and CAD/ CAMs bine together, the characteristics is the molding tool size accuracy high, the manufacturing period is short, the cost is low, is the new product manufacture on a trial basis, the small batch quantity produces the craft material of new applicable to the creation large overlay the piece to pull to stretch the mold( also can the part inset the steel), vacuum to absorb the and gather the ammonia ester hair bubble to model the mold, porcelain and ceramics mold and imitate the type to depend the mold and cast mold etc.. rubbers of system mold technique That technique take making a prototype or models as the basis, making into soft rubber of system piece, then depend the high pressure dint and models to fit together pletely. extrusions takes shape the technology cold extrusions takes shape Using the berylliuim copper alloy good thermal conductivity and the stability, after 5 the solid melt aging treatment of metal, use the swaging pressure to make the mold concave model cavity. Its characteristic is makes the cycle short, the cavity precision is high (the IT7 level), surface roughness Ra= mu m, The intensity is high, the life may reach 500,000 times, does not have the environmental pollution. ultra models takes shape the pattern making technology This technology is using the metal material in the thin crystal grain, certainly takes shape the temperature, under the low distortion speed condition, when the material has the best superplasticity, toes attend to carry out raised mold which the initiative finishes, then may extrude the concave mold with the small strength one kind of fast economical pattern making technology. Ultra models takes shape material typical representative is Zn22%AL. 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 the snapping back forming 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。 , 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. 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 technology, the socalled solid casting is (polystyrene PS either polymethacrylate PMMA) manufactures using the foam plastics replaces traditional the wooden mold or the metal pattern, after the modelling does not have to take out the model, then may the casting, under the foam plastics model high temperature liquid metal function, deflagrate the gasification but to vanish, the molten metal substitution original foam plastics model holds the position, after the condensation forms the casting. The solid casting has the following several kind of situations in the practical application. dry sands solid casting Namely all does not do any cementing agent quartz sand modelling with 55100 goal, spreads with EPS or the PMMA foam plastics manufacture model hangs the 6 thick permeability good fireproof coating level, by enhances the casting superficially attractive fineness, prevented the fat sand or collapses the box. negative pactions casting The negative paction casting calls V law modelling. This technology is the use all does but does not have the cementing agent the quartz sand to make the molding sand, makes the model with EPS or the PMMA foam plastics, in under the plastic film seal condition, entire lets cast (vacuum degree ) carries on the liquid metal casting under the negative pressure condition, after the casting coagulates relieves the。
