What is Aluminum Extrusion and Profiles

Aluminum extrusion, also known as aluminum frames, refers to aluminum products of various shapes produced through the aluminum extrusion process.

This material undergoes extrusion and heat treatment processes, resulting in various complex deformations.

Aluminum profiles are widely used in fields such as construction, transportation, machinery, electronics, and power due to their advantages of being lightweight, high-strength, corrosion-resistant, recyclable, and easy to process.

The different meanings of Section Profile Extrusion and Frames

"Section" refers to the cross-sectional shape of aluminum profiles, including dimensions and geometric shapes of both inner and outer surfaces.

"Profile" emphasizes the overall shape and form of aluminum profiles, including the cross-sectional geometry (section) and longitudinal shape.

"Extrusion" emphasizes the manufacturing process of transforming aluminum into shaped profiles.

"Frames" refer to structures or components constructed using aluminum profiles. These frames serve as the skeleton framework for various applications such as windows, doors, furniture, and machinery.

• Brushing aluminum profile, brushed texture, usually silver-gray or gray.
• Shiny aluminum profile, highly reflective mirror-like surface.
• PVDF profiles.

Aluminum profiles production processes

1. Heating aluminum blocks or aluminum alloys to a molten state, then injecting the molten aluminum into molds through casting to form preliminary aluminum billets.

2. Heating the cast aluminum billets to an appropriate temperature, then extruding them into the desired cross-sectional shapes, such as round, square, rectangular, etc., using extrusion machines, forming the final aluminum profiles.

3. Pre-treating the surface of aluminum profiles, then performing anodizing, powder coating, fluorocarbon paint coating, wood grain transfer printing, etc., according to customer requirements.

4. Cutting the extruded aluminum profiles to the desired lengths and precision to meet tolerance requirements.

5. Drilling, milling, cutting, stamping, welding, bending, assembling, CNC machining the cut aluminum profiles.

6. Customizing professional packaging solutions for aluminum profiles according to customer needs.

Extrusion types of aluminum profiles

Aluminum alloy extrusion methods include Direct extrusion and Indirect extrusion.

Direct extrusion is the simplest production mode. In it, the die is stationary while the ram forces the billet through the die opening. The action of the billet and ram moving forward in the same direction has led to this method being called the forward or direct aluminum extrusion process. Direct extrusion is the simplest production mode, with the die stationary while the ram forces the billet through the die opening.

Indirect extrusion is a process in which the billet remains stationary, but the assembly on the end of the ram moves against the billet. It enables the pressing of harder alloys (2xxx, 7xxx) and products with smaller cross-sections due to the smaller extrusion pressures. Lower pressures also allow for lower pressing temperatures and consequently greater extrusion speed. This of course increases productivity.

Aluminum profiles common alloys

The cost of aluminum profiles depends on several factors

• The price difference between different aluminum alloy grades can be significant.
• Larger size specifications of aluminum profiles typically result in higher prices.
• Different surface treatment processes for aluminum profiles also lead to price variations. Anodized aluminum profiles are generally more expensive than painted ones.
• The price of aluminum profiles is influenced by market supply and demand dynamics.
• Bulk purchases in large quantities often result in better price discounts.
