Solar panel frames and their supporting structure pillars, tie rods, support legs and so on are new products for aluminum alloy material application markets, which have been implemented and promoted globally. The following points briefly introducing the production technology and key nodes of the solar photovoltaic aluminum profile manufacturing process.
①Optimize the design and manufacture of extrusion dies for aluminum profiles:
Extrusion die is an important tool to ensure the shape and dimensional accuracy of solar photovoltaic aluminum profile products. The design and production quality of extrusion die is an essential guarantee to achieve excellent quality, large yield, low consumption, high efficiency and low cost in extrusion production. Therefore, in order to produce high-precision photovoltaic aluminum alloy profiles, it is necessary to optimize the design and manufacture of extrusion molds.
②Adopt advanced extrusion mold manufacturing equipment:
High precision and advanced extrusion die processing equipment is the prerequisite to guarantee the metal extrusion die qualified. Hence, the production of photovoltaic aluminum alloy profiles should be adopted the state-of-the-art mold processing equipment to improve the processing accuracy and performance of the molds, such as, CNC, slow wire cutting, three-axis machining center, electric discharge machining center, etc.,
③Reasonable layout of the die holes:
In order to ensure the perfect symmetry of photovoltaic aluminum profiles, and improve production efficiency and yield, the layout of die holes must comply with the principle of central symmetry, and the use of multi-die holes symmetrical layout. In the mold design process, the bridge position should be designed on the non-decorative surface of the profile as far as possible to avoid exposing defects.
④Optimize extrusion die design work tape:
The working belt is the part that stabilizes the size of the product and ensures the surface quality of the product. When designing the length of the die working belt, it is requested to minimize the drop, gently change the length, and use the obstruction angle and the flow promotion angle to reduce the metal flow rate, so as to achieve the purpose of uniform metal flow and improve the surface quality of the profiles.
