2.3.4 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 completely.
2.4 extrusions takes shape the technology
2.4.1 cold extrusions takes shape
Using the berylliuim copper alloy good thermal conductivity and the stability, after 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=0.025 mu m. The intensity is high, the life may reach 500,000 times, does not have the environmental pollution.
2.4.2 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 Zn-22%AL.
2.5 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 computer 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
2.6 triumphant Uygur bright steel belt blanking fallls 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 composed. This kind of mold weight is light, only then 200kg, the processing precision for±0.35-0.50mm, may suit each kind of black and the non-ferrous metal 0.5-0.65mm tick sheet processing generally. The life may achieve 5-25 ten thousand, the production cost is low.
2.7 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 technology, the so-called 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.
2.7.1 dry sands solid casting
Namely all does not do any cementign agent quarta sand modelling with 55-100 goal, spreads with EPS or the PMMA foam plastics manufacture model hangs the 0.2-1mm thick permeability good fireproof coating level, by enhances the casting superficially attractive fineness, prevented the fat sand or collapses the box.
