At present developed industrial nation some big panies traded the mold speed to achieve astonishing degree, whether had fast trades the mold technology to bee for an enterprise technology advancement sign. The always tendency is reduces the mold to install on the equipment, to be fixed, the adjustment time, this both must give in the equipment structural design to consider, and must in the mold structural design, the standardized aspect consider, machine on work as far as possible placing machine under will do. ramming units bination technology The ramming unit bination technology is dies a resolve into each one simple unit the convention to die, according to the working procedure request, the arrangement bination, pletes the many kinds of ramming working procedure when the identical inferior stroke the new craft equipment, the work the ramming unit not with the punch press slide joint, only needs the slide attack then to plete the ramming work. When independent employment it is 1 plete mold. It may use for to process the sheet or the molding punch holes, falls the material, cuts the angle, the grooving, shuts off and the shallow stretch and so on. Has the assembly strongly, the easy to operate, the versatility, the efficiency is quickly good and so on the characteristic, suits the multi varieties specially, center the production. may process the plastic in mold manufacture application May process the plastic to be mon in the developed industrial nation application, specially in manufacturing industry 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 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 9 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 unceasi
