Product Presentation
Have you encountered any of these problems?
Out of control premium for long pieces
Length over 300 mm price doubled, cost out of control
False High of strength commitment
Nominal grade 12.9, insufficient hardness of actual core
Salt spray line collapses
48 hours corrosion, equipment life cut in half
High scrap rate of bending parts
Heat treatment deformation, assembly rate dropped by 40%
Addicted to delay of delivery
30-day extension of extra-long parts becomes normal

Do:
– length 1-1990mm | Grade 12.9(≤500mm)
– salt spray for 1000h (anodic oxidation of titanium alloy)
– ± 0.01 mm precision tolerance (to be confirmed by drawing)
Don’t:
– plastic/woodworking screws | strength below grade 4.8
– non-environmentally friendly processes such as hexavalent chromium plating
Bulk Confidential: 100,000 units minimum order reduced by 12%
Why It’s better:
The cost of turning in the own CNC shop is 40% lower than that of outsourcing
30% post-processing cost can be saved by cold heading process of titanium alloy
