Aluminum profile processing and surface treatment
Jun 27, 2018

Aluminum processing in the processing methods, there are rolling, extrusion, stretching and forging and so on. Before the 1930s, it was a manufacturing facility using copper processing. The processing cost was mainly used in aircraft manufacturing. After the 60s, with the rapid development of aluminum, its products can be used in aviation, construction, transportation, electrical and chemical industries. In the product category there are plates, strips, foils, pipes, bars, profiles, wire and forgings.

 

Aluminium profiles can be categorized into aluminum profiles, radiator aluminum profiles, industrial aluminum profiles, mounting aluminum profiles, and rail vehicle structural aluminum alloy profiles. And they are different in the processing method and the processing equipment used. There are some differences.

 

Surface treatment type in aluminum processing

Matte: Mainly to avoid the problem that the surface of the aluminum profile is too bright and light interference occurs during use.

 

Multi-tone surface treatment: Allows aluminum profiles to be available in a variety of colors, such as stainless steel, champagne, gold, titanium, and red, first mechanically and chemically polished, and then oxidized.

 

Electrophoretic painting: The aluminum surface is soft and lubricious, and can resist the erosion of cement and mortar acid rain.

 

Powder electrostatic spraying: It is to make aluminum profiles have good corrosion resistance, and can resist acid and alkali salt spray.

 

Plasma-enhanced electrochemical treatment: Its high cost but rich color, can have more than 20 kinds of colors. According to different needs of the color, and a very good decorative effect.
