aluminum Transformer housing

When manufacturing aluminum alloy shell, usually use extrusion (extrusion) process, the following are the requirements and precautions for extruding aluminum alloy shell in our factory:

Extrusion Requirements:

Design and mold manufacturing:

Design Requirements: Design the appropriate cross-section shape, wall thickness and connection structure according to the function and use of the shell to ensure that the requirements of mechanical strength, assemblage and aesthetics are met.

Die Manufacturing: Manufacture extrusion dies with high precision and durability. The quality of the dies directly affects the quality of the extrusion molding and the stability of the product.

Material selection:

Select aluminum alloy material suitable for extrusion processing, usually aluminum alloy round ingot or square ingot.

Requirements for materials with good extrusion properties, such as good plastic deformation capacity and uniform organizational structure to ensure the stability of the extrusion process and molding quality.

Extrusion process control:

Control the extrusion temperature: according to different aluminum alloy materials, control the appropriate extrusion temperature to ensure the plasticity and fluidity of the material.

Control of extrusion speed: Control the extrusion speed to ensure the uniformity and surface quality in the extrusion process.

Cooling and stretching:

The extruded aluminum profiles need to undergo rapid cooling and stretching to enhance their mechanical properties and dimensional accuracy.

The cooling and stretching process should pay attention to controlling the temperature and speed to avoid internal stress and deformation.

Attention:

Dimensional accuracy:

Ensure that the dimensional accuracy of the extruded aluminum alloy shell meets the design requirements to avoid oversize or undersize affecting assembly and use.

Regularly check the mold wear, timely adjustment and replacement to ensure product dimensional stability.

Surface quality:

Control the surface quality during extrusion to avoid surface defects such as extrusion flaws, scratches or bubbles.

After the extrusion is completed, carry out surface treatment, such as grinding, polishing or spraying, if necessary, to enhance the aesthetics and corrosion resistance of the product.

Structural design:

According to the application environment and functional requirements of the shell, design a reasonable structure to ensure that the shell can withstand the expected load and pressure during use.

Quality Control:

Establish a strict quality control system, including raw material inspection, extrusion process monitoring and finished product inspection, to ensure that product quality meets design and customer requirements.

Regular analysis and optimization of extrusion process parameters, continuous improvement of the production process, improve product consistency and stability.

Environmental protection requirements:

During the aluminum alloy extrusion process, ensure the safety of the production environment and waste disposal in accordance with environmental regulations, select environmentally friendly lubricants and processing fluids to reduce environmental pollution.

By strictly following extrusion requirements and precautions, the production of aluminum alloy shells ensures consistent product quality, dimensional accuracy and excellent surface quality for a variety of industrial and commercial applications.
