Welding-free, shortened construction period, cost reduction, metal crack repair.
Non-welding metal crack repair! We repair cracks without any thermal impact. This is a collection of repair achievements related to press equipment. Many other achievements are also available.
The "MS Method (Mechanical Stitch)" is a groundbreaking repair technique (Mechanical Stitch Method) that addresses metal cracks using mechanical methods. Since it does not apply any heat, there is no "thermal distortion." It prevents residual stress from occurring in other areas and also prevents secondary damage such as new cracks. Metal cracks are one of the concerns in equipment maintenance operations. In general welding repair methods, the base material around the crack changes due to heat, leading to residual stress and distortion, which always carries the risk of "crack recurrence" and "secondary damage." 【Features】 ■ 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 Please contact us for more details.

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 delivery times and lower costs. 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. 【Lineup】 ○ S Bolt → Ensures airtightness and removes cracks → Thoughtfully designed screw structure achieves pull-out 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 causes cracks to spread and strongly reinforces the base material ○ MS Bolt Hole Repair Insert → Female screw 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.
