Aluminum Extrusion Press Maintenance Manual

For many years, the Aluminum Extrusion Press Maintenance Manual has served our industry as a trusted resource built over decades by Al Kennedy, who dedicated himself to sharing knowledge freely.

Gemini Group acquired the manual and its website in 2025 with one goal in mind: to honor Al’s legacy by keeping the manual alive, current, and freely available to everyone in the extrusion industry.

If you would like to contribute something new, make a correction, or offer a suggestion on how we can improve the manual, please reach out.
