Let us understand the production process of aluminum solar panel frame. 1. Extrusion of solar aluminum frame aluminum profile, put the aluminum round cast rod into the extruder, extrude it through the frame aluminum profile die, immediately air-cooled and quenched, and quickly cooled down. 2. The solar aluminum frame is straightened.
Sealed into ethylene vinyl acetate, they are put into a frame that is sealed with silicon glue and covered with a mylar back on the backside and a glass plate on the front side. This is the so-called lamination process and is an important step in the solar panel manufacturing process.
4. The solar aluminum frame is sandblasted, and the aged aluminum profile is sent to the sandblasting machine for surface sandblasting. The surface of the solar aluminum frame aluminum profile after sandblasting can form a matt effect, which is very beautiful.
The solar aluminum frame has corners on the short sides, and the corners on both ends of the short sides need to be plugged and riveted, so that the corners are fixed and will not loosen. 10. Inspection of solar aluminum frame.
In order to make the frame more corrosion-resistant, the oxide film thickness of the solar frame profile is generally thicker than the film thickness of the material, and the corrosion resistance is stronger. Generally, there are two types of solar aluminum frames: black oxidation and natural oxidation.
The aging of the solar aluminum frame is to increase the strength of the aluminum profile by heating to a certain temperature and holding it for a certain period of time. 4. The solar aluminum frame is sandblasted, and the aged aluminum profile is sent to the sandblasting machine for surface sandblasting.
