Plastic mold is another kind of mold besides steel mold in mold products. Most of our common manhole covers, isolation piers, roads and slope protection bricks are produced by plastic cover molds, isolation pier molds and slope protection molds. Because compared with steel molds, plastic mold products are not only cheaper, lighter, easier to transport and use, but also more environmentally friendly and recyclable.

Plastic molds are mainly divided into slope protection molds, hexagonal slope protection molds, plastic slope protection molds, cover molds, slope protection mold boxes, cement slope protection molds, slope protection plastic molds, high-speed slope protection molds, concrete slope protection molds, prefabricated slope protection molds, hollow hexagonal slope protection molds, solid slope protection molds, slope protection brick plastic mold boxes and a series of slope protection products. Production of hollow hexagonal slope protection mold, solid hexagonal slope protection mold, slope protection brick mold, colored brick mold, cover plate mold, etc. The surface of the mould is smooth, and there will be no air holes on the surface, so the error of the produced slope protection brick and cover plate is very small.

Moreover, plastic molds with various specifications and patterns can be customized according to users' needs, and full-computer and automatic injection molding equipment and production technology are adopted, with higher precision.

In recent years, the development of plastic mold is very rapid, and the application scope and field are gradually expanding, which is inseparable from the continuous innovation and technological progress of plastic mold manufacturing technology. At present, the proportion of plastic molds in the whole mold industry is about 30%, and the proportion in mold import and export is as high as 50-70%. In the future mold market, its proportion will gradually increase.
