Endless Aluminum Extrusion Possibilities

At Northern States Metals, the range of aluminum extrusion applications is endless. Few applications are too big – or too small.

One of the key reasons for the growth of aluminum extrusion applications is the nominal costs of dies. Also, extruding complex aluminum shapes in most cases is more cost effective than forming, rolling or machining.

From the simplest to the most intricate profile, Northern States Metals has the expertise to meet all of your aluminum extrusion requirements. Our continuing commitment to quality, research and development, and service to our customers makes us a recognized leader in the aluminum extrusion industry. Our custom design makes for endless extrusion possibilities.

The aluminum extrusion process is one of the most economical ways to manufacture parts that have a constant cross section because the designer can put the metal "where he wants it." Often, extruding is the only method that can be used.

Machining many lengths of metal to particular cross section is typically more costly than extruding a similar number of pieces. Machining costs are additive; each additional piece requires almost that same amount of time and labor. Scrap resulting from machining often weighs more than the finished work.

Fabricating shapes by welding is also costly. Each piece must be welded where costs do not decrease by much volume. In some instances the cost of the necessary welding jigs is significantly higher than the cost of the extrusion die that would be necessary to produce the same shape.

The cost of roll forming dies is substantially higher relative to extrusion dies. Additionally, roll forming cannot be used where wall thickness varies. The thickness of the metal remains the same post bending.

Sand and permanent-mold casting results in parts that may need extensive finishing before use. Aluminum extruding produces a wrought structure with relatively close dimensional control. Casting mold costs rise more rapidly than aliminum extrusion dies as the part complexity increases.

Extrusion dies are comparatively inexpensive. Forming dies and casting models generally run to thousands of dollars whereas extrusion dies can be used for a fraction of the cost. More extruders stock many standard dies which the customer can use without a die service charge. Extrusion dies can be finished with less lead time than forming dies and casting molds.

Aluminum extruders will also store and maintain the die without charge. Most aluminum extrusion dies can be installed in a press quickly, therefore set-up charges are nominal. The lifetime of extrusions dies also holds a large advantage due to its infinite span of duration.

While many metals can be extruded, aluminum is the overall extrusion metal of choice because of its unique combination properties.
