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 mor

e 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.

The process flow is:

Blank heating → hot extrusion → sawing → turning and boring → blank heating → secondary extrusion → tension straightening or roller straightening → cutting collet → intermediate inspection → annealing → corrosion → scraping repair → cold rolling → annealing → heading → stretching → quenching → sizing → finishing and straightening → cutting finished product sampling → artificial aging → finished product annealing → inspection and acceptance → oiling and packaging

Seamless aluminum pipe is extruded by piercing, while conventional aluminum pipe is extruded by combined die. The extrusion process of short rod, high temperature and slow speed shall be adopted in production. In particular, the "three temperatures" shall be well controlled. The aluminum rod, extrusion cylinder and die shall be kept clean. The aging time and temperature shall be properly adjusted according to the thickness of pipe wall and the size of pipe diameter.

1: 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.

2: Aluminum bar heating:

The heating treatment of aluminum rod shall ensure the temperature control. If the temperature is too high or too low, it will directly affect the hardness of the final product, so the temperature must be strictly controlled during heating and cooling;

3: 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;

4: 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.

5: 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.

6: 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.

7: 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
