For those new to the aluminum extrusion process, the example below is a fun way to show how the process works. The aluminium profiles extrusion process is similar to this PlayToy press in that the malleable dough is forced through the press and flows through the opening fitted with a particular die shape.
Once the desired shape for the finished profile has been developed and the appropriate aluminum alloys selected, an extrusion die, and associated tooling, is produced. In the actual extrusion process of HAOMEI factory, the aluminum billet (a cast "log" of extrusion feedstock) and extrusion tools are preheated. During extrusion aluminium, the billet is still solid, but has been softened in a furnace. Note: The melting point of aluminum is approximately 1,220° Fahrenheit (660° Centigrade). Extrusion operations typically take place with billet heated to temperatures in excess of 700°F (375°C), and — depending upon the alloy being extruded — as high as 930°F (500°C).
The actual extrusion process in HAOMEI workshop begins when the press ram starts applying pressure to the billet within a container. Hydraulic presses can exert from 100 tons to 15,000 tons of pressure; the pressure capacity of a specific press determines how large an extrusion it can produce.
