QC Profile
All the roll forming machines produced by our KYT Machinery have ourselves strict standard quality
control process:
Parts Inspection

Forming Rollers
45# Steel, CNC lathes, fine polished, coat hard Chrome thickness 0.02-0.05mm for anti-rust and improve
forming rollers’ hardness. All the forming rollers will be spot inspected before installation.
Cutting Blades
The cutting blades material can be Cr12, C12Mov or SKD11 for our kinds of roll forming machines. Before
cutting blades be installed on cutting frame, the hardness will be tested for ensure the using life.
Whole Roll Forming Line Inspection
Check the whole line each parts are on list or not at first, then adjust the roll forming machines to required
