[National Coverage] A new technology for crack repair without welding: the LNS method. Unlike traditional welding repairs, it does not apply heat that damages the base material of the equipment.
Cracks have occurred in your company's important equipment. "Is it safe to weld? I don't want to weld... I'm anxious." "Let's try grinding the crack first!... No good." "If we use a stop hole... No good." After consideration, welding was implemented... But it broke again! Welding is the only way to connect it! Just needs to last for a while! However, have you ever had an experience where the results did not meet your expectations? With Locknstitch (LNS method), we can meet your company's expectations! There are things that can only be done with mechanical joining that does not use heat. It can accommodate all types of metals. Unlike conventional welding repairs, we do not apply heat that damages the base material of the equipment. By not applying heat, secondary cracks do not occur, and heat treatment and machining are also unnecessary. As a result, repairs can be completed in a short period, leading to extended equipment life with precision, durability, and low cost.

basic information
<Merits> ■Repair Time Repairs can be completed quickly as they are carried out using air-operated tools that do not require complex methods such as preheating. ■Ease of Installation The head of the screw (PIN) is designed with a groove at the top to allow for removal with a consistent torque, and the straight shape of the main body enables uniform quality work regardless of the installer. ■Clean Finish LNS pins have their shoulder inserted inside the surface, preventing exposure during installation, which allows for a clean surface finish after installation due to metal-to-metal contact. ■Maintaining Air Tightness LNS pins are installed evenly without uneven stress during installation, allowing for air tightness without the need for epoxy or adhesives used in other similar products, enabling high-pressure air tightness. ■Holding Power LNS pins and locks are installed at all crack locations, providing strong holding power. ■Wide Range of Applications LNS products can be applied in various situations and conditions with diverse sizes of screws and locks, particularly suitable for corners and rounded edges. ■On-Site Work In most cases, repairs can be performed on-site.

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.
