Factory Quality Control
PO=>Make production plan(By professional QA team)=>Select perfect raw material(100% checked by CZPT Analyzer)=>Cut raw material(marking transfer)=>Heating&forged(production record to control the forge ratio=>HT after forged(Time&TEMP record)=>check black forged(grain size,UT&Sizes)=>rough machining(UT&Sizes)=>Heat treatment(controlled by computers)=>check mechanical property&hardness(universal testing machine&KING hardness tester)=>Semi finish machining(UT,MT&sizes)=>final check(all QC records)=>Packing&warehousing(all docs)=>delivery on time |
