Company introduction Cangzhou Bohai Explosion-proof Special Tools Group Co., Ltd. was founded in 2008 and established a group company based on Cangzhou Bohai Explosion-proof Tools Manufacturing Factory with a registered capital of 10,000 yuan It is a well-known large-scale explosion-proof product manufacturing enterprise in China. The company has five major series of products: explosion-proof tools, explosion-proof electrical and anti-static products, anti-magnetic tools and special tools. The products include multiple categories and nearly 10,000 specifications.
What are explosion-proof tools? The material of explosion-proof tools is copper alloy. Due to copper's good thermal conductivity and almost carbon-free characteristics, the heat generated in a short period of time when the tool and object rub or impact is absorbed and conducted. Another reason is that copper itself is relatively soft due to friction and impact. It has good concessions and is not easy to produce tiny metal particles, so we can hardly see sparks. Therefore, explosion-proof tools are also called spark-free tools.
