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 work process, preventing the occurrence of re-cracking due to thermal distortion. Since heat curing is also unnecessary, we can perform work in a short delivery time. Additionally, we carry out repairs of both small and large threaded holes, as well as 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 of equipment and metal structures in various industries (such as petroleum, chemicals, power generation facilities, ships, heavy machinery, automobiles, steelmaking, etc.) using the METAL STITCHING method. Currently, most of the critical equipment used across industries is facing a challenging situation for 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 thoroughness for extending the life of equipment and providing high-quality and rapid maintenance by avoiding issues such as deformation from heat and secondary cracking, which have been problems with traditional welding repairs, while also achieving shorter construction periods and lower repair costs. For repairs where you want to avoid using fire or where time is limited, please contact LNS JAPAN.
