Industry

Laser cladding and laser quenching technologies are widely used in the automotive manufacturing field for the repair of wear on high-tech automotive vulnerable parts and the strengthening of new products. Laser cladding technology is a high-precision and high-efficiency surface modification technology. By heating and melting the surface of automotive parts with a laser beam and spraying metal powder, a strong coating is formed, which can enhance the wear resistance, corrosion resistance and high-temperature resistance of the parts. This technology is widely applied in the automotive manufacturing industry.

Engine component manufacturing and repair

Cylinder block and cylinder head repair: After long-term use, the cylinder block and cylinder head of a car engine are prone to problems such as wear, cracks and corrosion. Laser cladding technology can carry out local repairs, reduce material waste and costs, restore the original shape and performance of cylinder blocks and cylinder heads, and enhance the power and reliability of automobiles.

Fuel injector manufacturing: Traditional fuel injector manufacturing and assembly are complex, and leakage and clogging problems are prone to occur. The adoption of laser cladding technology can achieve integrated manufacturing, reduce the number of parts and assembly steps, and enhance the reliability and performance of fuel injectors.

Cylinder liner manufacturing: A wear-resistant coating can be formed on the surface of the cylinder liner to enhance its wear resistance and durability, and extend its service life.

Turbocharger and exhaust pipe manufacturing: Form high-temperature and corrosion-resistant coatings on the inner walls of the turbocharger impeller and exhaust pipe to enhance the service life and performance of the components.

Brake system repair and manufacturing: Brake discs. Brake discs are key components of the braking system. Laser cladding technology can form a strong coating on their surface, enhancing the wear resistance and heat dissipation performance of the brake discs, thereby improving braking effect and service life, and ensuring driving safety.

Surface strengthening and repair of automotive molds: After automotive molds have been in operation for a period of time, their surfaces may fail due to wear, corrosion, etc. The application of laser cladding technology in mold repair can extend the service life of molds. For instance, the molds for automotive body panels often have roughening defects. After being repaired by laser cladding, the surface of the molds becomes smooth without pores or sand holes, and the qualification rate of the workpieces can reach over 96%.

Repair and strengthening of other components: For metal components on automobiles that require wear resistance, high-temperature resistance, corrosion resistance, and oxidation resistance, such as exhaust valves, commutators, gears, etc., laser cladding can be adopted to enhance their surface hardness, correct metal deformation areas, improve organizational properties, and increase service life. In addition, laser cladding of Fe-based alloy powder on the 45 steel crankshaft connecting rod journal can make the hardness of the cladding layer 2 to 3 times that of the base material, which can solve the problems of easy wear and cracking of the crankshaft journal and prevent the overall scrapping of the crankshaft.
