New technology for repairing metal cracks that are not welding: MS method for repairing cast iron cracks.

New technology for repairing metal cracks that are not welding: MS method for repairing cast iron cracks.

We will repair the cracks that have developed in the metal without applying any heat. Since no heat is applied, there is no thermal distortion at all.

The "MS Method (Mechanical Stitch)" is a groundbreaking repair technique (Mechanical Stitching Method) that addresses metal cracks using mechanical methods. Since no heat is applied at all, there is no "thermal distortion." Residual stress does not occur in other areas, preventing secondary damage such as new cracks. Metal cracks are one of the concerns in equipment maintenance operations. In typical welding repair methods, heat alters the base material around the crack, leading to residual stress and distortion, which always carries the risk of "crack recurrence" and "secondary damage." **Features of the MS Method** - No hardening or residual stress from heat - Elimination of secondary damage - Maintenance of stable quality → Integrated system repairs using jigs, etc. → Accumulation of know-how, experience, and track record - Completion of construction in a short period → No significant reduction in the operating rate of equipment - Advantages in safety and environmental aspects → No use of fire, so there is no impact on the operating rate of other equipment or the environment For more details, please contact us.
