After more than 20 years of development

Equipment resources of run aluminum products: 13 international advanced aluminum profile extruders, with an annual production capacity of more than 20000 tons; More complete aluminum profile precision processing equipment; More complete aluminum profile oxidation pretreatment equipment, including polishing, wire drawing, sand blasting and other equipment. Environmentally friendly anodizing production line. The total plant area is about 30000 square meters. It is a manufacturer integrating "aluminum profile extrusion, precision machining and surface treatment".

The company is located in the Yangtze River Delta with superior geographical location, leading science and technology and developed transportation in China.

Yurun aluminum products has served thousands of enterprises and is a long-term partner of many state-owned enterprises, multinational corporations and the world's top 500 companies.

Our fields include: automobile industry, aerospace, industrial automation, medical devices, home decoration, home appliance electronics and other industries.

Most of the radiator aluminum profiles are processed into blanks by aluminum extrusion, further sawed into the required length, then machined into the required state by punching or milling slots, and finally anodized into the required color.

Material selection of raw materials:

Industrial aluminum profile is a kind of industrial frame profile obtained by heating through aluminum bar and extrusion through die, while aluminum bar is formed by melting and casting through aluminum ingot, which is called industrial aluminum profile raw material; Raw materials will directly affect the performance of industrial aluminum products.

Mold design:

Industrial aluminum profile is the final product of aluminum bar extruded by die after heating, and the die is an instrument with high-precision specifications designed according to the demand to extrude profile products with required specifications and sections;

Industrial aluminum profile extrusion: extrusion temperature is the most basic and key process factor for extrusion production. The extrusion speed must be carefully controlled in the extrusion process.

Straightening correction of industrial aluminum profile:

There will be some deviation after extrusion of industrial aluminum profile. After forming, straightening correction shall be carried out by straightening machine. The industrial aluminum profile just extruded shall be corrected to the required tolerance range. Straightening correction must be completed by straightening machine to ensure its accuracy.

Artificial aging:

The aluminum profiles produced by extrusion have low hardness before aging and can not be used as finished products. Therefore, generally speaking, they must be aged to improve the strength.

Sand blasting + oxidation process:

After extrusion, the surface of industrial aluminum profile will have obvious stretch lines, and the surface pores are large and relatively rough, so it must be sandblasted

The so-called anodic oxidation of aluminum is an electrolytic oxidation process. In this process, the surface of aluminum and aluminum alloy is usually transformed into a layer of oxide film, which has protective, decorative and some other functional characteristics.
