Aluminum extrusion is a vital process in manufacturing, but it comes with inherent risks. The processes involved in aluminum extrusion, particularly when using an Alco aluminum extrusion press, can pose significant safety risks. Therefore, implementing key safety measures is crucial to protect workers and ensure efficient operations.[1] This article will explore comprehensive strategies to prevent aluminum extrusion press injuries, ensuring a safer work environment for all involved.
Understanding the Aluminum Extrusion Process
Before delving into safety measures, it's essential to understand the aluminum extrusion process. The extrusion process can be compared to squeezing toothpaste from a tube. The continuous stream of toothpaste takes the shape of the round tip, just as an aluminum extrusion takes the shape of the die. By changing the tip or die, different extrusion profiles can be formed. If you were to flatten the opening of the toothpaste tube, a flat ribbon of toothpaste would emerge. With the aid of a powerful hydraulic press which can exert from 100 tons to 15,000 tons of pressure, aluminum can be extruded into just about any imaginable shape.[3]
The process generally follows these steps:
1. A die is cast from the cross-section of the desired shape.
2. Aluminum billets are heated in a furnace to approximately 750 to 925ºF, where aluminum becomes a soft solid.
3. Smut or lubricant is applied to the billet and ram to prevent sticking.
4. The billet is transferred to a steel extrusion press container.
5. The ram applies pressure, pushing the billet through the container and die.
6. The soft but solid metal is squeezed through the die opening and exits the press.
7. The process continues with new billets welded to previous ones.
8. When the formed profile reaches the desired length, it's sheared off and cooled.
9. The cooled extrusion is straightened and work-hardened on a stretcher.
10. Extrusions are cut to desired lengths.
11. The parts are either cooled at room temperature or moved into aging ovens for heat treatment.[3]
This complex process involves high temperatures, immense pressure, and heavy machinery, all of which contribute to potential injury risks.
