PRODUCTION PROCESS BASED ON NATIONAL STANDARD

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

02 Preheat Aluminum Billet
Then preheat it in an oven to about 400-500 ℃. This process makes the billet malleable enough to carry out the operation. It also ensures that it is not molten.

03 Extruding
The heated aluminum billet is pushed through the openings in the tool. Those openings can be modified to create different shapes and sizes.

06 Aging
Qualified extrusions are put into the aging oven to bring the material back to its original hardness.

05 Stretching
The extruded bars are run through a strengthening process, which stretches the bars and ensures their mechanical properties by removing the internal tension within the bars.

04 Controlled cooling
The quenching process is necessary to ensure the required mechanical properties and adequate material microstructure.
