This makes the mold at least as critical-and many cases more so-for the quality of the end product as, for example, the plasticiting unit or other components of the processing equipment. The mould is important handicraft equipment，occupies decisive position in industrid departments such as consumer goods，electrical equipment electron，automobile , aircraft fabrication. The mould is important handicraft equipment , occupies decisive position in industrid departments such as consumer goods，electrical equipment electron，automobile , aircraft fabrication. Industrial product part rough process 75%, the finish machining 50% and plastic part 90% will be completed from the mould. The Chinese mould market demand already reaches scale of 500 hundred million yuan at present. The automobile mould , the annual growth rate covering piece of mould especially will exceed 20 %; Also prompt building material mould development，various heterotype material the mould，wall surface and floor mould become new mould growth point, plastic doors and windows and plastic drain-pipe increase to exceeding 30 by in the upcoming several years %; The home appliance mould annual growth rate will exceed 10 %; The IT industry year increases % speed equally exceeding 20，the need to the mould accounts for 20 of mould marketplace %.2004 annual Chinese machine tools implements industry output value. Will continue to increase. Our country mould fabrication market potential is enormous. The basis data counts， in recent years，our country mould year gross output value reaches 3 billion U. S. dollar，entrance exceeds 1 billion U. S. dollar，exceed 100 million U. S. dollar outlet. Increase by from 25% to increase to 2005 50% of 1995. The expert
