Q7:How do you manage the product quality? what main screening machines do you have? and which connected experienced certification do you have?<\/strong>A:We totally comply with ISO treatment to manage the quality, like fist inspection, material inspection, manufacturing inspection and cargo inspection and so on.We own tests devices like Rockwell appratus,Vickers harness tester, Salt spray tests equipment,Two dimensional projector,Torquemeter,Hexavalent chromium tester,Groove depth gauge,Hydrogen embrittlement examination fixture and so forth. all the machines are regularly calibrated by the third get together each and every year. We acquired ISO:9001-2015 qualification certification.
Q8:Can the products be automated assembled? What the variety can the reject ratio be managed?<\/strong>A:It is the question most client issue. At presnt,in order to increase the diploma of automation and boost the competitive gain of merchandise in the industry,most producing factories around the entire world use the equipment to automatically assemble goods. All quantities of our exported screws with previously mentioned 100K items will be entirely inspected by the optical nail picking equipment,to guarantee the steadiness of automatic assembly.<\/p>\n
