What is Aluminum Extrusion? The Process in 10 Steps
The use of aluminum extrusion in product design and manufacturing has increased significantly in recent decades.

According to a recent report from Technavio, between 2019-2023 the growth of the global aluminum extrusion market will be accelerating with a Compound Annual Growth Rate (CAGR) of almost 4%.

Perhaps you’ve heard of this manufacturing process and are wondering what it is and how it works.

Today we’ll discuss what aluminum extrusion is, the benefits it offers, and the steps involved in the extrusion process.

We’ll begin with the most basic and essential question.

Step #1: The Extrusion Die is Prepared and Moved to the Extrusion Press

First, a round-shaped die is machined from H13 steel. Or, if one is already available, it is pulled from a warehouse like the one you see here.

Before extrusion, the die must be preheated to between 450-500 degrees celsius to help maximize its life and ensure even metal flow.
