Shaped mold slope at this stage is not yet widely applied in large quantities, to control the costs, Rong Wu highway slope protection brick mold boxes, steel molds currently on the market are customized steel sheet metal, mold, although more expensive than the cost of plastic mold, high speed slope brick mold boxes, but eliminates the need for chain slope mold mold cost, factory direct slope protection brick mold boxes, steel mold plastic mold over all aspects of performance and service life is much higher plastic mold two or three times, the overall computing down or steel mold cost-effective. Our chain slope mold technology after decades of development, continuous improvement and innovation, especially in recent years, investment in universities and research institutes of scientific research forces, as well as the integration of production so that our chain slope mold industry is developing rapidly. In actual production, some plastic molds produced matte, it seems not a very good first impression. Is uneven because polypropylene plastics material molten mass, which requires should be an appropriate increase in the injection molding machine barrel heating temperature or increasing the screw Working back pressure; Moreover, if the high water content in the polypropylene material, then drying the raw material should also, the feedstock moisture content is controlled within the allowable range; then the inner wall, requires grinding, machining, in order to achieve the surface smoothness than high purpose, so as to make the production out of precast concrete high quality.
