The manufacturing process flow of solar aluminum frame

Manufacturing process flow of solar aluminum frame. The manufacturing process of photovoltaic aluminum frames is divided into four stages: casting, extrusion, oxidation, and deep processing.

1) Melting: Waste aluminum is added to an alloying furnace or a melting and insulation furnace for melting, and alloy modifiers are added in proportion for refining. The aluminum alloy melt that meets the process requirements is introduced into a direct cooling molding machine for forming, and cooled to form an aluminum rod;

2) Extrusion: By using an extruder equipment, the aluminum rod heated at high temperature is extruded at a constant speed through the mold, forcing it to undergo plastic deformation and extrude from the mold hole of the extrusion mold, so that the aluminum material reaches the shape and size given by the mold hole, forming a semi-finished profile;

3) Oxidation: Aluminum alloy undergoes electrochemical reaction in sulfuric acid solution to form an aluminum oxide protective layer through anodic oxidation;

4) Deep processing: Using different processing techniques, the oxidized aluminum alloy profiles are further made to form photovoltaic frames that are easy for customers to assemble.

After the initial manufacturing process, there are several additional steps that are crucial in creating high-quality solar aluminum frames. These include cutting, drilling, bending, welding and surface treatment.

Cutting involves using specialized machinery to cut the semi-finished profiles into specific lengths according to customer requirements. This step is important in ensuring precision and accuracy in the final product.

Drilling is necessary for creating holes in the frame where mounting brackets can be attached. This allows for easy installation of the solar panels onto roofs or other structures.

Bending is a critical step that gives the frames their required shape and angle. Specialized machines are used to bend the profiles with precision, as even slight deviations can affect the efficiency of the solar panels.

Welding is used to connect different parts of the frame, creating a strong and durable structure. This step requires skilled technicians to ensure proper alignment and weld quality.

Surface treatment involves applying a protective coating on the frames to prevent corrosion and increase durability. This can include powder coating, anodizing or painting depending on customer preferences.

The cost of manufacturing solar aluminum frames may vary depending on several factors such as raw material costs, production efficiency, and additional steps required for customization. However, it is important to note that investing in high-quality frames can have long-term benefits in terms of product durability and improved solar panel performance.

In addition to its use in photovoltaic systems, aluminum frames also have a variety of applications in other industries such as construction, transportation, and electronics. The lightweight yet strong properties of aluminum make it an ideal material for various structural and functional purposes.

As the demand for renewable energy sources continues to grow, the manufacturing process of solar aluminum frames will likely see further advancements and innovations to improve efficiency and sustainability. With continuous improvements and developments in technology, the future looks bright for this important component in the rapidly expanding solar industry.

So while we may have reached the end of this document, the evolution and potential of solar aluminum frames is far from over. More research and development is needed to continue improving their production process, durability, and overall impact on renewable energy.
