Roll playback and repair

Roll playback and repair

We perform cutting and grinding processing of various materials such as steel components and plated coatings!

This is an introduction to the repair and regeneration of rolls by Kōei Techno System Co., Ltd., which focuses on the repair, regeneration, extension of life, and maintenance of parts, aiming for high-quality parts and advanced machinery through research and development in areas such as wear resistance, heat resistance, and corrosion prevention, similar to preventive medicine. We perform regeneration and repair related to the paper industry and others. 【Self-fusing alloy thermal spraying on rolls (powder-type flame spraying)】 Powdered thermal spraying material is introduced into an oxygen-acetylene (or hydrogen, propane) flame, where it is melted and simultaneously accelerated by the combustion gas flow, causing the molten powder to collide with the substrate and form a film. Almost all metals, alloys, and cermets can be thermally sprayed, but generally, self-fusing alloy thermal spraying, abradable thermal spraying such as nickel-graphite, and plastic thermal spraying are widely used after re-melting treatment. The thermal spray gun is lightweight and easy to handle, has relatively high spraying efficiency, and produces low noise. ■ Self-fusing alloy thermal spraying on rolls ⇒ Photo 1 ■ Re-melting treatment of rolls ⇒ Photo 2 *For more details, please download the catalog or contact us.

Water chamber anti-corrosion treatment coatings, etc.! We carry out restoration and repair of railway-related, bus-related, and industrial machinery.

This is an introduction to Kōei Techno System's "Reconstruction and Repair of Diesel Engines," focusing on the repair, regeneration, extension of life, and maintenance of parts, with an emphasis on high quality, wear resistance, heat resistance, and anti-corrosion, similar to preventive medicine, aimed at advancing machinery through research and development. Founded in 1946, we have a history of approximately 70 years and have introduced welding and thermal spraying technologies early on in the internal combustion engine industry, primarily focusing on the repair (restoration) of engine parts. We conduct regeneration and repair for railways, buses, industrial machinery, and more. **Cylinder Head Repair** We perform crack welding, corrosion welding, valve guide installation, seat ring replacement, surface grinding, hydraulic testing, and seat grinding. **Cylinder Head Repair ⇒ Photos 1 to 5** **Cylinder Block Repair** We carry out line boring, oversize boring, surface grinding, crack welding, corrosion welding, and anti-corrosion treatment coating for water jacket areas. **Cylinder Block Repair ⇒ Photos 6 to 10** *For more details, please download the catalog or contact us.*

Screw regeneration and repair

Screw regeneration and repair

Forms a high-quality coating with strong adhesion and high density! Suitable for thermal spraying of cermets such as WC-Co.

This is an introduction to Kōei Techno System's "Regeneration and Repair of Screws," which focuses on the repair, regeneration, extension of life, and maintenance of parts, aiming for high quality, wear resistance, heat resistance, and corrosion prevention, similar to preventive medicine, through advanced research and development of machinery. 【High-Speed Frame Thermal Spraying (HVOF Spraying)】 This is a type of gas thermal spraying that uses a super high-speed jet stream generated by combustion with high-pressure oxygen. Because the material collides with the substrate at high speed, it forms a coating with very high adhesion and density, resulting in high-quality films. It is suitable for spraying cermets such as WC-Co, yielding high-hardness wear-resistant coatings. We perform restoration and repair related to industrial machinery. ■ Spraying on Screws ⇒ Photo 1 *For more details, please download the catalog or contact us.

Regarding the reinforcement and repair of the opening component "dock shelter" for factories and warehouses.

Regarding the reinforcement and repair of the opening component "dock shelter" for factories and warehouses.

The "dock shelter," which prevents the inflow of outside air and serves as a buffer with the truck, deteriorates over time. Would you like to repair and reinforce the old pads?

The dock shelter consists of a pad wrapped in a sheet made of polyurethane foam, but if the sheet gets partially torn, the tear can widen, causing the foam inside to be scraped off, or the edge of the sheet may get caught on a truck, potentially detaching the entire dock shelter. To prevent this, a new sheet is placed over the pad to reinforce it and maintain safety. 【Benefits of Dock Shelter Reinforcement Repair】 ● It reinforces the damaged areas of the pad. ● The appearance returns to like-new condition. (Note: The metal parts remain as they are.) ● It is cost-effective compared to replacing the pad with a new one, and it generates minimal waste, making it eco-friendly. (Note: Depending on the condition of the underlying structure, replacing the pad may be necessary.) ● An optional heat-insulating sheet can also be included. ● Methods can be chosen according to the budget. ■ For more details, please download the materials and take a look.

MS crack repair, blow molding machine crack repair, casting equipment, bolt hole repair.

Welding-free metal crack repair! We will repair metal cracks without applying any heat! Crack repair that does not cause any thermal distortion!

【Product PR】 The "MS Method (Mechanical Stitch)" is a groundbreaking repair technique (Mechanical Stitching Method) that uses mechanical methods to address cracks in metal. Since no heat is applied at all, there is no "thermal distortion." Residual stress in other areas does not occur, preventing secondary damage such as new cracks. Cracks in metal are one of the concerns in equipment maintenance operations. In typical welding repair methods, the base material around the crack changes due to heat, leading to residual stress and distortion, which always carries the risk of "crack recurrence" and "secondary damage." 【Features of the MS Method】 ■ No hardening or residual stress from heat ■ Elimination of secondary damage ■ Maintenance of stable quality → Integrated system repairs with jigs, etc. → Accumulation of know-how, experience, and achievements ■ Completion of work in a short period → No significant decrease in the operating rate of equipment ■ Advantages in safety and environmental aspects → No use of fire, thus no impact on the operating rate of other equipment or the environment For more details, please contact us.

Non-thermal metal crack repair Mechanical stitch crack repair Repair

Non-thermal metal crack repair Mechanical stitch crack repair Repair

We will repair cracks that have occurred in metal and machinery without applying heat. Since no heat is applied, there will be no thermal distortion at all.

The "MS Method (Mechanical Stitch)" is a groundbreaking repair technique (Mechanical Stitching Method) that addresses metal cracks using mechanical methods. Since it does not apply any heat, there is no "thermal distortion." It prevents residual stress in other areas and avoids secondary damage such as new cracks. Metal cracks are one of the concerns in equipment maintenance operations. Repairs using conventional welding methods change the base material around the crack due to heat, leading to residual stress and distortion, which always carries the risk of "crack recurrence" and "secondary damage." **Features of the MS Method:** - No hardening or residual stress due to heat - Elimination of secondary damage - Maintenance of stable quality → Integrated system repairs using jigs, etc. → Accumulation of know-how, experience, and achievements - Completion of construction in a short period → Does not significantly reduce the operating rate of equipment - Advantages in safety and environmental aspects → Since no fire is used, there is no impact on the operating rate of other equipment or the environment For more details, please contact us.
