Lunda Baoding building materials mold factory in recent years, China's plastic covers mold production process, there has been greatly improved, computer-aided technology, high-speed processing technology, hot runner technology, gas-assisted technology, reverse engineering and other new technologies are widely used. China's mold industry should speed up the digitization, the pace of information technology, efforts to enhance the fine design and finishing capabilities. Overall performance plastic covers mold is between Stone Sculpture covers and concrete covers, better than concrete; covers technology can be applied to situations requiring high. Plastic mold covers most prominent advantage is the use of glass fiber reinforced composites, are GRC products. Concrete curing speed several times faster than the fiber, 8 hours may stripping, if three shifts of production, releasing three times 24 hours, although the amount of mold than Shisu, but only about 1/6 of fiber reinforced concrete covers, can also be reduced Mold investment.
