The Harder welding line uses the Mega Line imported from Italy, and the whole line is highly intelligent and unattended. A set of steel plate radiators of the conventional size Type 22 600x1000 has more than 1600 solder joints, so that the precise and intensive welding process can only be completed with the advanced LEAS fully automatic welding line.
The waterway plate adopts automatic continuous spot welding technology to ensure uniform and stable solder joints.
Domestic machines or manual solder joints cannot guarantee that each solder joint is consistent, and it is easy to handle water leakage.

Radiator Surface Preparation

Degreasing

Removing the grease on the surface of the radiator by means of wetting, infiltration, rolling, dispersing and compatibilizing.

Pre-treatment of phosphate-free nano-film

Protect metal corrosion by phosphate-free nano-film technology; used for primer before painting, improve the adhesion and corrosion resistance of paint layer, is ordinary pickling phosphorus 2.5 times, greatly improving the life of the radiator.

Electrophoresis

high mechanical strength, strong adhesion, corrosion resistance, aging resistance, 3 times that of ordinary powder coating.

Epoxy resin electrostatic spraying

resistance to discoloration and corrosion resistance, the temperature reaches 180-190 °C workpiece does not change color, product color lasting and beautiful, excellent corrosion resistance.

MATERIAL SELECTION

STAUDESTAHL is one of Germany's leading suppliers of cold-rolled sheets. It is an excellent material and is the best choice for steel plate radiators. STAUDESTAHL's steel metal has good thermal strength and 1.5 times the thermal conductivity of ordinary steel.

Henkel has the world's leading innovation, strong brand and advanced technology, and is the best choice for metal pretreatment. Henkel's pre-treatment fluid enhances the adhesion to the paint, and its anti-corrosion performance is 2.5 times that of pickling and phosphating, which greatly prolongs the service life of the radiator. Mercedes-Benz, Chrysler, Land Rover Jaguar, and Tesla use Henkel's pre-treatment fluid.

BASF is one of the most famous chemical companies in Germany. BASF's electrophoretic primer is baked at a high temperature of 200 degrees Celsius to make the surface of the radiator super corrosion-resistant. It is twice as much as ordinary primer. Mercedes-Benz and Porsche use BASF paint.

AkzoNobel, the world's top ten paint brands, the world's leading industrial company, the world's largest paint company. After being baked at a high temperature of 200 °C, AkzoNobel plastic powder has a bright, long-lasting color, which is three times that of ordinary plastic powder.

Aluminum: International ADC12 aviation special aluminum, is a special aluminum for international aviation, good die-casting, is the preferred aluminum for cast aluminum radiator
