Explosion-proof tools have been applied in special fields such as domestic petroleum, chemical, oil refining, oil and gas transportation as early as the 1980 s. However, since the domestic explosion-proof tool industry was not developed at that time, it could only be imported from abroad with foreign exchange, which was not abundant at that time. In order to allow customers to use our own explosion-proof tools, Hebei Zhongbo Explosion-proof Tools Co., Ltd. as the representative of the domestic production enterprises after several years of efforts and continuous practice, and finally manufactured domestic explosion-proof tool products. Over the past 30 years, China's explosion-proof tool manufacturers have always adhered to technological transformation and scientific and technological investment, and silently realized the dream of building China into a world explosion-proof tool manufacturing power through practical actions. According to industry insiders, at present, the explosion-proof tools made in China account for about 80% of the global market space, and the explosion-proof tools made in China occupy a certain position in the international market. According to customs statistics, the products of Hebei Zhongbo Explosion-proof Tools Group Co., Ltd. have reached more than 94.6 percent of the country's export of explosion-proof tools for five consecutive years. The company's domestic market share also reached more than 80%. According to the release of domestic explosion-proof tool manufacturing industry, Hebei and Tianjin are the most concentrated areas of explosion-proof tool industry, especially in Botou City. Botou not only has a large number of explosion-proof tool manufacturers, but also a large-scale explosion-proof tool professional manufacturer-Hebei Zhongbo Explosion-proof Tool Co., Ltd. is located here. At present, China's explosion-proof tool industry has entered the ODM independent design and production stage from the initial OEM OEM production stage. At present, China's explosion-proof tools have advanced manufacturing technology and have entered the fifth-generation product stage to gain a competitive advantage in the international market. ● The first generation of products, learn from the European Danish casting process, cast tire blank processing molding, to the market, to fill the national gap. Cast tire products have pores, trachoma, casting shrinkage, rough surface is not standardized, easy to bend, easy to shape, easy to break, short service life. Note: From 1983 to 1989, domestic materials were manufactured and 23 beryllium bronze smelting and production patents were obtained. ● Second-generation products. The surface of steel mold casting products was refined quickly, which solved the surface blisters and improved the quality of some products, but they were still steel mold casting tire products. In a product over phase. Note: From 1990 to 1998, domestic material manufacturing, creating beryllium bronze, aluminum bronze smelting and manufacturing process patents 28 third-generation products, precision casting process precision casting products, smooth surface, uniform density, no pores, no sand holes, improve the accuracy of the product, alloy mechanical properties, improve the competitiveness of domestic and foreign markets. Note: From 1999 to 2006, 36 patents for beryllium bronze and aluminum bronze manufacturing and appearance were created for domestic material manufacturing. ● The fourth generation of products. The die forging manufacturing process company successfully created the copper alloy die forging process, changed the production process of explosion-proof tools, and calendered them with six sets of friction presses of 150-4000T according to the tool size, creating many national patents. Advantages: high density, good toughness, smooth surface, clear handwriting, not easy to bend, not easy to break, uniform hardness, long service life. Note: from 2007 to 2016, the use of foreign Kazakhstan high-quality beryllium master alloy, and undisclosed matching method, enhanced the competitiveness of domestic and foreign markets, to export brand-name products, the world's top explosion-proof tools. Manufacturing beryllium bronze explosion-proof tools and aluminum bronze explosion-proof tools, obtaining 43 patents) ● Fifth generation products, intelligent precision forging manufacturing process selects imported raw materials, improves smelting matching method, newly enters 3 sets of die forging hammers and 4 sets of precision forging machines, beryllium bronze explosion-proof tools and aluminum bronze explosion-proof tools have all obtained EXIIC grade in the non-ignition test of the national testing station, and establishes the national CNAS laboratory and explosion-proof tool technology center. The explosion-proof tools produced by Zhongbo have surpassed various technical parameters in the international market, with appearance accuracy ≤ 6.3 μm, standardized, automated and intelligent production, full coverage of DIN standard die forging, novel appearance design, introduction of international advanced technology and automatic packaging of novel body. Note: Since 2017, 9 patents have been created.
