5. Shafts used in many industries
AutomotiveindustryMicro shafts of car part series
White goodsindustryMicro shafts of home electric appliance series
Power tools industryMicro shafts of electronic tool and motor
Office industry Micro shafts of office article series
Communication industryMicro shafts of sounder and communication part series
Hardwareindustry Micro shafts of hardware and instrument series
6.Processes
We often use ERP system to producing quality control, the processes for the shafts are usally the following:
Raw material(Drawn) → Cutting→Rolling →lather→grinding→polish→final inspection→pick up→package→delivery
We can offer PPAP documents,such as control plan, PFEMA, Process flow .etc
7. Raw material
Materials:
Carbon steel:SK45 CK45,EN8,60#,70#,80#
Stainless steel :SUS303,SU304, SUS316, SUS416,SUS420J2
Others: AISI4140, 42CrMo,ETG88 1144 12L14,430f,431100Cr6, SUJ2, Gcr15
Raw materials are ROHS tested from the third party every year, such SGS, CTI.
8. Machines:
Ball Grinding machines, to make the end of shafts
Auto lathers, to do lather process, like groove
Coreless grinding machines- this are the most important machines making the shafts
9. Testing devices, we have our own testing certer. we have all shafts devices
10 Package of the products
11 Export
We have our import-export right to export the products. Till now , our shafts are export to USD, KOREA, SPAIN, INDIA,JAPAN. TURKEY. ETC.
