What is the LOCK-N-STITCH LNS method? Metal crack repair technology

What is the LOCK-N-STITCH LNS method? Metal crack repair technology

This is a technology that uses specially designed screws and reinforcement materials (LOCK) at the metal crack site to physically remove the crack with a metal touch and bond the metal together.

■□■ A completely new method for repairing metal cracks that is not welding ■□■ The process involves drilling, tapping, and inserting special screws and reinforcement materials (LOCK), and unlike traditional welding repairs, it does not apply heat that could damage the base material of the equipment. By avoiding 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 improved precision, durability, and lower costs. For more details, please contact us.

Metal crack repair technology "LOCK-N-STITCH" LOCK technology

Metal crack repair technology "LOCK-N-STITCH" LOCK technology

Used to increase strength across metal cracks. When used in combination with LOCK and C series pins, it allows for high-strength and permanent repairs.

■□■A completely new metal crack repair that is not welding■□■ The strength reinforcement material "LOCK" is made of "4130 steel" and is heat-treated to maintain a tensile strength of 175,000 psi (12,200 kg/cm²). LNS Lock is manufactured by cutting with EDM wire for precision, making it superior to Roll Type and Punch Type locks in all aspects. Since the Lock cannot be bent, it cannot be applied to the corners of uneven areas and is only usable on flat surfaces. For more details, please contact us.

Concrete Waterway Protection and Repair Technology "OM Lining Method"

Concrete Waterway Protection and Repair Technology "OM Lining Method"

A concrete channel protection and repair technology that allows for economical and efficient maintenance of waterways!

The "OM Lining Method" is a waterway protection and repair technology aimed at extending the service life of waterways by quickly forming a strong waterproof membrane on concrete surfaces. Thanks to its anti-corrosion technology, it is durable over the long term while maintaining flexibility. Additionally, both the friction coefficient and roughness coefficient are low, which improves water flow and reduces the accumulation of mud. 【Features】 ■ Slippery surface ■ Sustained flexibility ■ Wear resistance ■ Improved roughness coefficient ■ Ice detachment properties *For more details, please download the PDF or feel free to contact us.

Salt damage repair technology "Composite anti-corrosion method"

Salt damage repair technology "Composite anti-corrosion method"

Economical, safe, reliable, and easy! Construction is possible with the minimum required amount of excavation.

Chubu Nippon Highway Engineering Nagoya Co., Ltd. (Engineering Nagoya) offers a "Composite Corrosion Prevention Method" that is an efficient repair technology for concrete members suffering from deterioration such as delamination due to rebar corrosion caused by salt damage, capable of "suppressing rebar corrosion over the long term." By using sacrificial anode materials (immediate effect) combined with high-concentration rust prevention mortar (long-term effectiveness), we can stop salt damage with a double effect. This method can reduce the "chipping depth" in cross-section repair work, thereby lowering the risk of re-deterioration. Additionally, it allows for a reduction in the need for specialized technical elements. 【Features】 ■ Economic, safe, reliable, and simple ■ Reduction of re-deterioration risk ■ Decrease in the need for specialized technical elements ■ Long-term suppression of rebar corrosion *For more details, please refer to the PDF document or feel free to contact us.

Metal crack repair technology "LOCK-N-STITCH" C series pins

Metal crack repair technology "LOCK-N-STITCH" C series pins

Ideal for cross-shaped cracks that occur on the upper part of the cylinder head or cracks that have developed from plug holes or bearing holes.

■□■A Completely New Metal Crack Repair That Is Not Welding■□■ The "C Series Pin" is a representative screw that showcases LNS's excellent technology. The CASTMASTER (C Series Pin) does not diffuse cracks; rather, it works in the opposite direction. In short, this pin features a special form of thread known as a "Spiral hook," which has a different angle compared to conventional screws. It pulls the crack areas together and secures them permanently. The key point is the thread design, which differs from standard screws. It is advisable to use the largest diameter pin possible, and it can be applied from a thickness of 0.25" (approximately 6mm). For further details, please contact us.

Metal crack repair technology "LOCK-N-STITCH" L series pins

Metal crack repair technology "LOCK-N-STITCH" L series pins

The screw hole size and the taper at the base are characteristic features. There are three different diameters, each with varying lengths, and they are made of steel or aluminum.

■□■ A completely new metal crack repair that is not welding ■□■ The "L Series Pin" is designed so that the size of the screw hole for the L Series Pin is 1/1000 inch smaller than the size of the pin, and it has a large taper (7 degrees) at the base of the screw. When tightened, this causes about three threads of the female screw at the top of the screw hole to be crushed. The L Series Pin is used when the repair area does not penetrate the inside or outside of a corner or does not pass through the plug hole and bolt hole, or when there is no need to additionally increase structural strength. It eliminates the gap at the crack site while also serving the role of sealing and preventing loosening, demonstrating excellent effectiveness. For more details, please contact us.
