4. Long life and easy to recycle: aluminum alloy service life is generally more than 30 to 50 years, and the service life of the panel is generally 25 to 30 years, can fully meet the use requirements; The melting temperature of aluminum is low, about 660℃, scrap products are easy to regenerate. The recovery rate is very high and the energy consumption of recovery is only 3% of the original aluminum, which is of great economic value and can effectively help energy saving and environmental protection.

Materials and techniques:

Our products use high-strength and corrosion-resistant aluminum alloy as the main material to ensure the durability and stability of the brackets. The manufacturing process flow of aluminum alloy photovoltaic frames is divided into four stages: melting and casting, extrusion, oxidation and further processing.

Melting and casting: Scrap aluminum is added into an alloying furnace or a melting and heat preservation furnace for melting. Alloy modifiers are added proportionally for refining. The aluminum alloy melt that meets the process requirements is then introduced into a direct cooling forming machine for forming, and after cooling, aluminum bars are formed.

Extrusion: Through the extrusion equipment, the aluminum bars heated at high temperature are extruded at a constant speed through the die, forcing them to undergo plastic deformation and be extruded from the die holes of the extrusion die, so that the aluminum materials can achieve the shape and size given by the die holes and form semi-finished profiles.

Oxidation: Aluminum alloy undergoes an electrochemical reaction in sulfuric acid solution, and an aluminum oxide protective layer is formed through anodic oxidation.

Deep processing: Different processing techniques are adopted to further fabricate the oxidized aluminum alloy profiles to form photovoltaic frame products that are convenient for assembly.
