Metal crack repair, metal restoration work, steel crack repair, cast iron crack regeneration.
We will repair the cracks that have occurred in the metal mechanically, rather than through welding. The repair will be done without generating any thermal distortion.
The "MS Method (Mechanical Stitch)" is a groundbreaking repair technique (Mechanical Stitching Method) that uses mechanical methods to address cracks in metal. Unlike welding repairs that involve thermal curing, this method does not apply any heat, thus preventing "thermal distortion." It does not generate residual stress in other areas, preventing secondary damage such as new cracks. 【Features】 ■ No hardening or residual stress due to heat ■ Elimination of secondary damage ■ Maintenance of stable quality → It is a unified system repair using jigs and other tools → Accumulation of know-how, experience, and track record ■ Completion of construction in a short period → It 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 or download the catalog.

Damaged Bolt Hole Repair Insert "MS Insert" The "MS Insert" is a female thread part designed to repair damaged bolt holes. It utilizes a special structure on the outer diameter thread section, which is embedded into the bolt hole area for restoration. It is difficult to pull out and does not impose a load on the base material, making it suitable for areas constantly exposed to vibrations or at the ends. Compared to conventional products such as spring-type coils and self-tapping types, it improves precision and demonstrates groundbreaking effects in terms of durability.

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.
