19、ld is a smooth upward, in the next Die market, the development of plastic mould faster than the other Die, die in the proportion of industry will gradually improve. With the continuous development of the plastics industry, put on the plastic mold growing demands is a normal, and so sophisticated, la

20、rge-scale, complex, long-life plastic mould development will be higher than the overall pace of development. At the same time, imports in recent years because of the mold, precision, large, complex, long-life die in the majority, therefore, reduce imports, increase Guochanhualu: perspective, in the

21、mold of such high-end market share will gradually increase. The rapid development of the construction industry so that the various Profile Extrusion Die, PVC plastic pipe fittings Die Die market become a new economic growth point, the rapid development of highways, car tires also put a higher demand

22、, radial tire Die, Die particularly active pace of development will also be higher than the overall average level of the plastic and wood, plastic and metal to make plastic molds in the automotive, motorcycle industry in the demand for huge household appliances industry in the 10th Five-Year Plan pe
