There are many non sparking tools manufacturers in the world now,maybe hundreds of ,as we think. But very only few ones which could produce high quality products,why? Here we want to write some points how to produce high-quality non-sparking hand tools f us ,as follows:
The purchase and use of non-sparking materials
First of all,which is also important is you should take more attention for the purchase and use of non-sparking materials.The quality is high or not of non-sparking tools depending on raw materials quality high or not,which is the basics of producing non-sparking hand tools,it is first step of making non-sparking hand tools-casting process.For reduce cost of producing,some companies may use low quality copper which have some impurities in it.But it’s dangerous and irresponsible for the end users,who will using them.As some impurities will caused spark when working. While the raw materials of HEBEI OUYANG SAFETY TOOLS are import from Kazakhstan,where the copper materials are high grade pure,so the HEBEI OUYANG SAFETY TOOLS of Non-Sparking Hand Tools series are high quality and perfect ones.
The producing process of non-sparking safety hand tools
Some factories are using casting ways to produce tools,which is pouring copper water in a mold only,use above style,the tools are porosity, casting shrinkage porosity, rough and irregular surface, easy to bend, easy to change, easy to break, short used life.
While HEBEI OUYANG SAFETY TOOLS are using punch forged process to make the non-sparking tools a higher hardness and torque ,also increased density,make the tool surface more clean and tidy.
In the smelting and casting process, random sampling of inspection test blocks and test bars meeting the requirements of gb10686 standard, according to the non sparking safety performance required by the non sparking safety tool standard and the highest level EXIIC, drop weight test and friction spark free test are conducted in the hydrogen concentration of 21%, so as to ensure the safety factor of non sparking safety performance of tool materials. The density of die forging products increased by 3% and the torque increased by 5%, which improved the strength and stable mechanical properties, thus achieving the use value of non sparking safety tools.
The testing of non-sparking hand tools
Non sparking safety tools are non used in inflammable and explosive environment. Life is very important and responsibility is very important. They not only achieve non sparking performance, but also conform to stable mechanical functions. HEBEI OUYANG SAFETY TOOLS company has successively established material non sparking performance laboratory, material chemical composition analysis laboratory, alloy material spectrometer, tool pulling laboratory, tool torque laboratory, material elongation laboratory, tool hardness laboratory, pliers multi-function laboratory, screwdriver torque laboratory to ensure the safety and stability of non sparking safety tools and other technical indicators.
