This is an introduction to the construction results of the LOCK-N-STITCH (LNS method), which repairs cracks that occur in metal using special bolts and reinforcement locks.
■□■ A completely new method for repairing metal cracks that does not involve welding ■□■ 【Example of Achievements】 ○ Upper part of the crown side cover (forged press) → The forged press machine had oil leaks at the expanding areas, and crack repair (900mm) was completed in two days. ○ Additional hole processing at the crankshaft journal end → Completed in two days at eight locations. ○ Gear → A second break occurred from the welded area, reinforced with LNS reinforcement material (repair period: two days during the day). ○ Marine M/E cylinder block → The aging ME engine of the ship, made of a material difficult to weld, was repaired using the LNS method (repair period: 2.5 days). We have many other achievements as well. For more details, please contact us.

basic information
Our company is the Japan General Service Center certified by Lock-N-Stitch in the United States, providing repair services and Lock-N-Stitch (LNS) products. [Certification held] We have numerous achievements in a completely new metal crack repair technique that does not involve welding. This crack repair technology does not apply heat during the process, preventing the occurrence of re-cracking due to thermal distortion. Since heat curing is also unnecessary, we can perform work in a short turnaround time. Additionally, besides crack repairs, we also carry out the restoration of both small and large threaded holes and new hole drilling work. ● For more details, please contact us.

Company information
<We provide nationwide support> LNS JAPAN Co., Ltd. is an engineering company that performs maintenance and repairs on cracks and damages in equipment and metal structures across various industries (such as petroleum, chemicals, power generation facilities, ships, heavy equipment, automobiles, steelmaking, etc.) using the METAL STITCHING method. Currently, most of the critical equipment used across industries is facing a tough situation regarding new capital investment due to the global economic downturn. In Japan's industries, welding technology, which is widely used for metal repairs, has recently led to significant damage to many pieces of equipment and critical assets due to a shortage of skilled craftsmen and inexperienced welding repairs, with many cases worsening. Our company is the only certified company in Japan and is committed to continuous technological development in collaboration with our parent company, LOCK-N-STITCH INC, which continues to leap and grow as a global enterprise. We promise to ensure that our repairs do not cause deformation or secondary cracks due to heat, which have been issues with traditional welding repairs, while also shortening construction periods and reducing costs, thereby extending the life of equipment and ensuring high quality and prompt maintenance. For repairs where fire is not desired or where time is limited, please contact LNS JAPAN.
