Thread restoration, bolt hole restoration, welding-free metal crack repair work, casting repair.
We will repair damaged female threads to the same size as the original. Repairs can be made without generating any thermal distortion.
【Basic Information】 Metal crack repair using the MS method 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 construction can be performed 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. 【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 causes cracks to spread and strongly reinforces the base material ○ MS Bolt Hole Repair Insert → Female screw part to reinforce 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.
