Description

Technical Field

[0001] This utility model relates to the field of aluminum extrusion die technology, and in particular to a hot extrusion die for solar panel frame profiles. Background Technology

[0002] With the rapid development of the solar energy industry, the market demand for aluminum profiles for solar panels is increasing. The traditional one-out-one solution can no longer meet customers' expectations for production efficiency. Aluminum profile manufacturers also urgently need to reduce costs and increase production capacity. Against this backdrop, the industry is gradually shifting to the one-out-two extrusion method to improve production efficiency and reduce production costs.

[0003] However, during the hot extrusion process, increasing the extrusion speed often leads to defects such as black lines on the profile surface. Specifically, the profile surface is prone to roughening, which eventually manifests as obvious black lines after oxidation. This not only affects the appearance quality of the product but may also negatively impact the mechanical properties of the profile, thereby reducing its market competitiveness.

[0004] Therefore, there is an urgent need for a new type of hot extrusion die to solve the black line problem encountered in the production of solar panel frame profiles. This die should ensure the quality of the profiles and production efficiency to meet the growing market demand. To this end, we propose a hot extrusion die for solar panel frame profiles.
