QC Profile

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

Parts Inspection

Machine Frames

Depends on roll forming machine’s size , we have 20#, 35#, 45# and may other bigger sizes H-beam for choise, after blasting and derusting, we weld each pieces of H-beam and then polish the weld place, finally paint whole roll forming frame together.

Rolling Shaft

45# forged steel or 40Cr, thermal refining and finishing lathe.

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 dimensions to get correct roll forming samples, check the roll forming samples surface, dimensions according to design drawing, even two pieces sample joint effect. If not reached the required standard, the engineer will adjust whole machine to solve the problem together with our designer.
