The aluminum pipe must be degreasing treatment before polishing. According to the degree of sludge contamination on the surface of the polished parts, generally one of the following two degreasing processes can be selected for treatment. The sludge on the surface of aluminum pipes is slightly contaminated and distributed more uniformly. We usually use a weakly corrosive alkaline degreasing liquid. Its composition and operating conditions are as follows: Sodium silicate is a corrosion inhibitor, which can inhibit the corrosion of aluminum. A layer of aluminum silicate film is formed on the surface of aluminum parts when using corrosion inhibitors. Therefore, after degreasing and cleaning, it must be followed by a sludge removal treatment (often called light out) in a solution containing fluoride ions.

The shapes of the aluminum tubes produced are: triangle, circle, ellipse, square, rectangular, concave and convex outside, convex outside the circle, peach-shaped triangle double plane, concave outside the circle, inner rib, U-shape, eight-character, eight-character concave , Single plane ellipse, square-round combined tube, flat tube, thin wall, capillary, elbow, and aluminum rod (below 3.0), aluminum branch, etc. Main uses: camera tripod, electronics, U disk, electric heating, electrical appliances, fiber optic connectors, antennas, stylus, cosmetics.

Aluminum and aluminum alloy pipes have higher surface quality requirements, but their hardness is not high, especially in hot conditions. Therefore, great care must be taken during the production and shipment process to prevent bumping against hard objects. This requires strengthening the protection of the product during production and lifting, and at the same time, it must be handled with care and protection during work. Surface, civilized production.
