Square plastic covers mold has many unique properties, square covers mold can replace the cast iron, high strength cement and FRP products, road inspection covers and rain grate, good market prospects, square covers mold to the national A-level standard capacity calculation costs, respectively, compared with the other 2-4 times lower covers all materials, plastic covers mold to produce products with good impact hungry covers tensile strength plastic mold manufacturers, and wear square covers plastic mold, corrosion-resistant, beautiful covers the supply of plastic mold, no noise, environmental protection, combined with tight bottom, light weight, can be any color and other characteristics. Our country is mold production and use of power, must produce a lot of waste plastic covers mold plastic mold covers every year, which requires a comprehensive set of molds recycling programs do Good Die recycling. Recycling of waste mold, smelting and processing can be carried out again, so that it can change waste into treasure. Elimination of waste plastic covers mold casting it again as a new material, or re-used in the production or processing of other products mold, and back and forth through this production, not only solve the problem of waste mold processing enterprises, but also the development of mold cycle economy. China's plastic mold covers researchers developed and invented a special mechanical password security lock covers, manhole covers stolen can solve the problem, the technology has gained the State Intellectual Property Office granted patent. This covers theft lock with anti-drilling, anti saw, anti-pull, anti-shock, anti-stress, anti-corrosion and anti-intrusion feature. Each lock has a different password, can unlock through a dedicated modem line opening function. Cylinder at the precise production is the most important, both to effectively prevent corrosion, but also effectively deter theft. The new anti-theft locks can be used for many covers. However, due to the high prices, there is no widely used throughout the country. Jiangsu covers mold plastic mold _ Guohui (certified) _ covers plastic mold mold by Baoding Guohui Machinery Co.
