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 production of aluminum shell of charging pile is to extrude the aluminum rod into profile, then cut it into the required length, further use CNC machine to drill holes and mill grooves to become an accessory that can be installed, and finally anodize to form a protective film that is beautiful and can protect the material from corrosion

extrusion

Extrusion is a means of profile forming. Firstly, the die is designed and manufactured according to the profile product section, and the heated round cast rod is extruded from the die by extruder. The common grade 6063 alloy also uses an air-cooled quenching process and subsequent artificial aging process during extrusion to complete heat treatment strengthening. Different grades of heat treatable strengthening alloys have different heat treatment systems.

称CNC加工，自动车床加工，数控车床加工等。

（1）用车、铣、刨、钻、磨等通用机床加工模具零件，然后进行必要的钳工修配，装配成各种磨具。

（2）精度要求高的模具零件，只用普通机床加工难以保证高的加工精度，因而需要采用精密机床进行加工。

（3）为了使模具零件特别是形状复杂的凸模，凹模型孔和型腔的加工更趋自动化，减少钳工修配的工作量，需采用数控机床（如三坐标数控铣床，加工中心，数控磨床等设备）加工模具零件。

Coloring (here we mainly talk about the oxidation process)

Oxidation: the surface corrosion resistance of extruded aluminum alloy profile is not strong, so the surface treatment must be carried out through anodic oxidation to increase the corrosion resistance, wear resistance and appearance beauty of aluminum.

The main processes are:

(1) Surface pretreatment: clean the profile surface by chemical or physical methods to expose the pure matrix, so as to obtain a complete and dense artificial oxide film. Mirror or matte (Matt) surfaces can also be obtained by mechanical means.

(2) Anodizing: for the surface pretreated profile, under certain process conditions, the substrate surface will be anodized to form a dense, porous and strong adsorption Al2O3 film.

(3) Pore sealing: seal the pores of the porous oxide film generated after anodic oxidation, so as to enhance the anti pollution, anti-corrosion and wear resistance of the oxide film. The oxide film is colorless and transparent. By using the strong adsorption of the oxide film before sealing the hole, some metal salts are adsorbed and deposited in the film hole, which can make the appearance of the profile show many colors other than the natural color (silver white), such as black, bronze, golden yellow and stainless steel.
