As early as the 1980s, explosion proof tools have been used in China's petroleum, chemical, refining, oil and gas transportation, and other special fields. However, since the explosion-proof tool industry in China was not developed at that time, it could only use the foreign exchange which was not abundant at that time to import from abroad. In order to enable customers to use the explosion-proof Tools made by China, the Chinese manufacturers represented by the Hebei Botou safety tools group finally made the domestic explosion-proof Tools after years of effort and continuous practice.
Over the past 30 years, Chinese explosion-proof tool manufacturers have always insisted on technological transformation and investment in science and technology, and quietly realized the dream of building China into a world explosion-proof tool manufacturing power through practical actions.
According to the introduction of the industry, at present, the explosion-proof tool products made in China account for about 80% of the global market space, and the explosion-proof tool products made in China occupy a certain position in the international market.
According to customs statistics, Hebei Botou Safety Tools Group's products accounted for more than 94.6% of the country's exports of explosion-proof Tools for five consecutive years. The company also has more than 80% of the Chinese market.
According to the release of the explosion-proof tool manufacturing industry in China, Hebei, and Tianjin are the most concentrated areas of the explosion-proof tool industry, especially the botox city. Botou not only has a large number of explosion-proof tool manufacturers but also Hebei Botou Safety Tools Group, a large professional manufacturer of explosion-proof Tools.

Explosion Proof Tools
At present Chinese non-sparking tools industry has been developed from the initial production stage of OEM brand in ODM independent design and production stages. At present, China's explosion-proof tools have advanced manufacturing technology, into the fifth generation of products, in the international market to obtain competitive advantages.
Gain a competitive advantage in the international market.
● the first generation of products, drawing lessons from the European Danish casting process, cast tire blank processing and forming, to the market, fill the national gap.
There are porosity, trachoma, loose casting, rough surface, easy to bend, easy to change, easy to break, short service life. Note: from 1983 to 1989, China made materials and obtained 23 beryllium bronze smelting and production patents
● the second generation of products, the steel casting process
Steel die casting product surface refinement fast, solve the surface sand hole, improve the quality of some products, but it is still steel die casting tire products. In a product transition phase.
Note: from 1990 to 1998, China has 28 patents on materials manufacturing, beryllium bronze, aluminum bronze smelting, and manufacturing process
● third-generation products, the precision casting process
Precision casting products, smooth surface, uniform density, no pores, no sand holes, improve the accuracy of products, alloy mechanical properties, improve the competitiveness of the Chinese market.
Note: from 1999 to 2006, China made materials and created beryllium bronze, aluminum bronze manufacturing, and appearance patents 36.
he fourth generation of products die forging manufacturing process
The company has successfully created the copper alloy die forging process, changed the production process of explosion-proof tools, and according to the size of the tools, used 150-4000t six sets of friction press rolling, creating a number of national patents. Advantages: high density, good toughness, smooth surface, clear writing, not easy to bend, not easy to break, uniform hardness, long service life.
Note: from 2007 to 2016, the company has made use of high-quality beryllium mother-alloy from Kazakhstan abroad and undeclared compounding methods to enhance the competitiveness of the Chinese foreign market and achieve the export of famous brand products and international top explosion-proof tools. Manufacturing beryllium bronze explosion-proof tools, aluminum bronze explosion-proof tools, obtained 43 patents)
● the fifth generation of products, intelligent precision forging manufacturing process
Selected imported raw materials, improved smelting method, 3 sets of newly imported die forging hammer, 4 sets of precision forging machine, beryllium bronze explosion-proof tools, aluminum bronze explosion-proof tools obtained EXIIC level in a non-ignition test of a national testing station, set up national CNAS laboratory, explosion-proof tools technology center. The explosion-proof tools produced by Hebei Botou have exceeded various technical parameters in the international market, with the appearance accuracy ≤ 6.3m, standardized, automated and intelligent production, complete coverage of DIN standard die forging, novel appearance design, the introduction of international advanced technology, and novel automatic packaging of the body.
