The steel mold of bridge isolation pier is suitable for high-speed and high-speed railway, and it is also a kind of hardware casting. The rise of hardware casting industry in China is relatively early, but the stagnation time in the later stage is relatively long, so China's mold industry, especially the steel mold industry, lags far behind developed countries. Take the steel mold of isolation pier as an example, Whether from the quality, precision and smoothness of the product itself, the product has a long distance. With the continuous development of society, China has paid more and more attention to the development of steel industry, gradually trained a group of professionals in hardware casting industry, and gradually filled the vacancy of steel mold in China. The production mode of isolation pier steel mold has gradually kept up with the international pace, changing the problems of rough steel mold, inaccurate molding, short service life and structure. With the continuous rise of steel molds, the self productivity of China's hardware mold industry has been improved, and the export volume has greatly exceeded the import volume. Now many foreign countries also follow China's production and sales model. Under such an optimistic environment, China is expected to become a big country in the hardware manufacturing industry. It has the characteristics of beautiful appearance and gives a good visual impact to people in modern life. At present, it has been widely used in municipal construction, garden construction, parking lot, factory, highway, wharf, machinery and other fields. At present, China attaches great importance to the manufacturing and development of ditch cover plate steel mold, especially in the quality control area. Even now, our ditch cover plate steel mold is applied to various fields, and the market response is quite good. The mold of isolation pier is used for the production of cable trench, drainage ditch, tunnel beam and road construction. The mold of isolation pier adopts steel plate to complete the size and shape required by the design through bending, welding, rounding and pasting. Angle iron is added outside the mold, and the shape of reinforcement is fixed
