Minalex is an industry leader in ultra-precision smaller aluminum extrusions. We regularly produce extrusions with tolerances as tight as +/- .001" on one or more dimensions, depending on the shape. This unique ability allows design engineers to specify extrusions in situations where close tolerances are required. The Benefits of close tolerance extrusions are that they perform better, fit together more securely and usually eliminate the need for additional machining. Few extruders would accept a challenge of .060" holes with +/- .002" tolerances, and some of them would give the project to Minalex. They know, as the industry knows, that Minalex is the right source for the cost-effective production of close tolerance extrusions up to 3 1/2" in diameter.
