  • Extrusions with Tight Hole Tolerances - Minalex

Minalex regularly produces aluminum extrusions with tolerances as tight as +/- .001" on one or more dimensions of an extrusion, depending on the shape. This unique ability allows design engineers to specify very small extrusions in situations where close tolerances are required. The benefits of these close tolerance, micro extrusions are that they perform better, fit together more securely and usually eliminate the need for expensive machining.

Walls as thin as 0.018" are also possible on one or more of the dimensions of an extrusion, depending on the shape. As the trend toward miniaturization and design simplicity continues, your need for a dependable supplier of precision aluminum extrusion profiles will surely increase.

Carriers used by electronics and other industries for various components are another area requiring extremely tight tolerances. Small and often minute parts are transported in openings that must be accurate to 0.001 inches (0.025 cm). Minalex pioneered the production of these extrusions and continues to be the leading manufacturer today.

Large Aluminum Extrusions

The precision achieved in aluminum extrusions is also possible up to 3.500 inches (8.89 cm) in diameter/circle size. Minalex regularly produces these close tolerance extrusions up to 1.500 pounds per foot (2.2322 kg per meter). Minalex's precision capabilities for Large Extrusions are just as effective at 3.500 inches (8.89 cm) as they are down at 0.018 inches (0.457 mm)!
