Aluminum Extrusion Services | Welleshaft

1.What Is Aluminum Extrusion? 

Aluminum extrusion is a manufacturing process where aluminum alloy is forced through a die to produce continuous shapes with a uniform cross-section. At Welleshaft, we offer high-precision Aluminum Extrusion Services that ensure structural strength and aesthetic quality. Our process enhances performance, reduces weight, and improves corrosion resistance. From T-slot rails to frames and enclosures, we support fast prototyping and mass production with reliable precision.

Extrusion Terminology Includes:

• Extrusion Ratio: Die area vs. billet area
• Extrusion Pressure: Required force for material flow
• Extruded Aluminum Process: From billet to cooled profile
• Hydraulic Extrusion Press: Main machine driving the process

2.Aluminium Extrusion Process Explained

Our process starts with aluminum billet preheating, then hydraulic pressing through precision dies. This creates seamless aluminum profiles tailored to your application. Below is the simplified flow:

📊 [Process Diagram Placeholder]
Billet → Heated → Extruded (Press) → Cooled → Cut → Machined (Secondary)

We use fully automated aluminum extrusion press machines and advanced extruder pressure control to guarantee consistency and dimensional accuracy across batches.

（1）Types of Aluminum Extrusion Profiles & Alloys

①Alloy Comparison Table

Alloy	Strength	Common Applications
6061-T6	Good corrosion resistance	Architecture, general purpose
7075-T6	High tensile strength	Aerospace, defense, tooling

3.Aluminium Extrusion Machining & Secondary Operations

We go beyond raw extrusion—we offer machined aluminum extrusion solutions for complex parts：

1.CNC machining

2.Drilling and tapping

3.Precision cutting

4.Bending and deburring

We support tight-tolerance projects and customized profiles for industries like automotive, solar, and industrial automation.

（1）How Do I Cut, Drill, or Bend Aluminum Extrusion?

Recommended: carbide-tipped saws, proper coolant, and customized dies for safe bending. Welleshaft offers full machining services for precise fabrication.

4.Common Aluminum Extrusion Questions

（1）What is the difference between 6061 and 7075 aluminum extrusion?

6061 is more weldable and machinable, ideal for general structures. 7075 offers higher strength but is harder to machine.

（3）How does an aluminum extrusion press work?

The hydraulic press pushes heated billets through a steel die using several thousand tons of force, shaping the material without defects.

5.Aluminum Extrusion vs Other Metal Forming Processes

Parameter	Aluminum Extrusion	Die Casting	Metal Rolling
Tooling Cost	Medium	High	Low
Design Flexibility	High	Medium	Low
Volume Suitability	Low–High	High	Very High
Strength-to-Weight	High	Medium	High

Welleshaft recommends extrusion for lightweight structural components where custom cross-sections are needed.
