1. Material selection
Aluminum alloy:
Advantages: Aluminum alloy has the advantages of light weight, high strength, corrosion resistance, good thermal conductivity and electrical conductivity.
Commonly used grades: 6063, 6061, etc., with excellent extrusion performance and subsequent surface treatment performance.
2. Mold design
Structure design:
Complex shape: Optical profiles usually have a complex cross-section design, including a variety of notches, holes and stiffeners, etc., to meet the installation and strength needs of photovoltaic systems.
Precision: Mold design requires high precision to ensure that the extruded profile size is accurate, the surface is smooth, and there are no obvious defects.
Cooling system:
Necessity: In the extrusion process, the mold will generate a lot of heat, a good cooling system helps to control the mold temperature and ensure product quality.
Method: Usually water cooling or oil cooling system.
3. Production process
Extrusion molding:
Process: After the aluminum alloy raw material is heated to the appropriate temperature, it is extruded by the extrusion machine through the mold to form the cross section shape of the light profile.
Control: Precise control of extrusion speed, temperature and pressure is required to ensure the quality and consistency of the profile.
Heat treatment:
Aging treatment: Extruded profiles usually require heat treatment (such as aging treatment) to enhance their mechanical properties.
Surface treatment: According to needs, the surface of the profile can be anodized, electrophoretic coating and other treatments to improve its corrosion resistance and beauty.
4. Application field
Photovoltaic bracket system:
Support structure: Optical profiles are widely used in the support structure of photovoltaic panels to provide stable and durable support.
Convenient installation: Through the design of a reasonable cross-section shape, the optical profile can be quickly installed and disassembled to improve construction efficiency.
Roof and ground installation:
Multi-scenario application: Suitable for roof photovoltaic system and ground photovoltaic power station, can cope with a variety of installation environment and conditions.
5. Performance requirements
Mechanical properties:
High strength: must be able to withstand wind load, snow load and other environmental loads to ensure the safety and stability of the photovoltaic system.
Durability: For long-term use in outdoor environment, it needs to have excellent corrosion resistance and anti-aging properties.
Accuracy and consistency:
Accurate size: The extrusion mold needs to ensure that the cross-section size of the profile is accurate, which is convenient for subsequent processing and installation.
Surface quality: smooth surface, no obvious extrusion marks and defects.
6. Mold maintenance
Regular inspection:
Wear condition: Check the wear condition of the mold regularly to ensure that it is working in the best condition.
Cleaning and lubrication: Clean the mold regularly, keep it clean, and properly lubricate it to extend the service life of the mold.
Repair and replacement:
Timely repair: Timely repair of problems to prevent affecting production quality.
Replacement of parts: if necessary, replace the key parts of the mold to ensure the continuity and efficiency of production.
Photovoltaic extrusion molds play a key role in the photovoltaic industry, and their design and production processes have a direct impact on the quality and performance of optical profiles. Through the selection of high-quality aluminum alloy materials, precise design of the mold structure, strict control of the production process and regular maintenance, we can ensure that the optical profiles meet the requirements of high strength, high durability and high precision of the photovoltaic bracket system, so as to support the efficient and stable operation of the photovoltaic system.
