RK Chain Laser Marking

In the DRIVE CHAIN market, quality requirements are increasing every day with an emphasis on chain weight and strength. Usually the chain maker’s name and chain model are punched on the outer-plates of the chain. These punched marks although mild and shallow, reduce the thickness of the plates and therefore reduce the fatigue resistance strength of the chain. We have modified our method of marking chain from punching to Laser 7 years ago. The following photos show each marking method.
