For 60 years, Minalex has built incredibly precise miniature aluminum extrusions, precision-cut components, and much more.
We’ve built precision partnerships grounded in technical expertise, close collaboration, and the consistent performance customers depend on when tolerances are tight and expectations are even tighter.
In industries where a few thousandths of an inch can influence fit, function, and long-term reliability, “close enough” is not enough. Design engineers turn to Minalex when they need a manufacturing partner that understands the demands behind the drawing: repeatability, dimensional accuracy, material integrity, and the process discipline required to deliver reliable parts from prototype through full production.
Our high standards are reflected in the numbers as well. Minalex regularly produces extrusions with tolerances as tight as +/- 0.001 inch on one or more dimensions, with walls as thin as 0.020 inch and capabilities for precision-cut sections down to 0.003 inch, with cut-down tolerances to 0.001 inch. Those figures are not just specifications. They represent the manufacturing discipline that helps customers achieve precise fit, reliable assembly, and dependable performance in every demanding application.
From the beginning, that focus has defined Minalex. Co-founder Jim Casey helped shape the company around a simple but visionary principle: “Do one thing and do it right.” Sixty years later, that philosophy continues to guide every customer relationship, every production improvement, and every investment in the capabilities needed to solve complex manufacturing challenges.
You’ll also find our commitment reflected in the case histories featured throughout this blog. We invite you to explore them for a closer look at how Minalex supports demanding applications in solar farms, industrial and EV manufacturing, and even nuclear submarines. Each story shows what precision partnership really means in practice: listening carefully, solving collaboratively, and producing parts that perform reliably in the real world.
As Minalex marks its 60th anniversary, we remain proud of the legacy behind us and focused on the opportunities ahead. The applications may evolve. The engineering challenges may grow more complex. But our mission remains the same: to help customers turn difficult tolerances into dependable results by doing one thing and doing it right.
For projects where precision matters, Minalex is ready to help.
