Heat preservation and crack repair technology with almost no risk of secondary crack occurrence, which does not require machining. Here is a list of products for screws and reinforcement materials used in the LNS method.
■□■A completely new metal crack repair that is not welding■□■ Contributes to the extension of equipment lifespan The work process involves drilling → tapping → inserting special screws and reinforcement materials (LOCK), and unlike traditional welding repairs, it does not apply heat that damages the base material of the equipment. As a result, repairs can be completed in a short period, leading to extended equipment lifespan with improved precision, durability, and low cost. The "C Series Pin" is ideal for crosswise cracks that occur on the upper part of the cylinder head or cracks that have developed from plug holes or bearing holes. The "L Series Pin" features a screw hole size and a tapered base. The "LOCK" is used to increase strength across the crack. 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.
