Metal crack repair, welding-free cold metal repair, MS method, cast iron crack repair.
We repair cracks in metal without applying heat! Metal crack repair that generates no thermal distortion at all! We can also handle castings that are difficult to weld.
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 achievements - Completion of construction in a short period → Does not significantly reduce the operating rate of equipment - Advantages in safety and environmental aspects → Since no fire is used, there is no impact on the operating rate of other equipment or the environment For more details, please contact us.

basic information
The MS method for repairing metal cracks demonstrates outstanding effectiveness in terms of precision, durability, and cost compared to conventional methods. It is a technology that physically repairs cracks using our special bolts and reinforcement plates. Since it can be implemented on-site, it allows for reduced lead times and cost savings. We have experience in a wide range of fields, including cast iron cracks, marine equipment, power generation facilities, and cement equipment. Please feel free to contact us if you have any questions. 【Product Lineup】 ○ S Bolt → Ensures airtightness and removes cracks → Thoughtfully designed screw structure achieves tensile strength of the base material ○ T Bolt → Prevents MS reinforcement plate from pulling out and patch repairs → Unique tapered section enhances airtightness and prevents loosening ○ MS Reinforcement Plate → Reinforces and restores the repair area → Suppresses the force that would cause cracks to spread and strongly reinforces the base material ○ MS Bolt Hole Repair Insert → Female thread part for reinforcing damaged bolt holes ・ HS Type Insert: For cases where there are no cracks around the bolt hole ・ HF Type Insert: For cases where there are cracks around the bolt hole

Company information
The mechanical stitch metal crack repair technology is a method that physically repairs metal cracks using special bolts and reinforcement plates (mechanical stitch method), which does not apply heat to the repair area, thus preventing thermal distortion in the crack repair (Mechanical Stitch method). In addition to metal crack repair, it also has the technology to regenerate damaged screw threads using repair inserts. Furthermore, since repairs can be performed on-site, it allows for reduced construction time and cost savings.
