Basics:
EXTRUSION PROCESS
The basic principle of extrusion is as simple and complex as squeezing ointment out of a tube. Pressure applied at the closed end of the tube forces the ointment to flow through the open end. The strand of ointment squeezed out takes on the shape of the tube opening
- round, square, hex or other.
The aluminum extrusion process begins with heating aluminum billets in a furnace to 750 to 900 degrees Fahrenheit. The aluminum is not liquid, but rather a malleable solid at the time of extrusion.

Penn Aluminum utilizes PLC automated presses to extrude aluminum. This
approach allows us to consistently extrude to customer specifications,
while enhancing the quality of the extrusion in the
process. Once extruded, the hot aluminum profile must be quenched, cooled, stretch straightened and cut.
Our attention to detail and documented processes
(ISO9002 & QS9000) assures you of dependable and repeatable quality extrusions that meet or exceed your expectations.
