Premier’s World-Class Aluminum CNC Machining Services

Since 1988, Premier Aluminum LLC has been a trusted leader in the aluminum casting industry, serving manufacturers across the automotive, aerospace, defense, medical, and industrial sectors. From our headquarters in Racine, Wisconsin, we have built a reputation as one of the most knowledgeable and experienced aluminum foundries in North America.

As part of our fully integrated capabilities, we provide Aluminum Machining services that ensure every casting we produce is precise, functional, and production-ready. Unlike foundries that only deliver raw castings, Premier Aluminum combines permanent mold casting expertise with advanced machining resources, giving our customers the advantage of a single-source supplier.

By keeping machining in-house, we eliminate the risks of outsourcing, reduce lead times, and maintain strict quality control at every stage. With over 70 machining centers and extensive finishing, tooling, and testing capabilities, Premier Aluminum delivers complete solutions — from raw aluminum to fully machined and finished components ready for assembly.

Advantages of Our Aluminum Machining

Choosing Premier Aluminum for aluminum machining means working with a partner that delivers precision, repeatability, and efficiency at every stage. Our machining services are specifically designed to add value beyond the casting process by producing parts that are dimensionally accurate, assembly-ready, and built to meet demanding performance standards.

Key advantages include:

  • Advanced CNC precision with 23 horizontal and 18 vertical machining centers capable of holding tight tolerances.
  • Integrated machining and casting workflow, reducing the need for secondary suppliers and minimizing handling errors.
  • Surface finishing accuracy, providing sealing surfaces, smooth fits, and high-quality aesthetics without extensive secondary operations.
  • Comprehensive quality verification with CMMs and laser scanning to confirm every dimension meets customer specifications.

Our commitment remains the same: High-Quality Castings, High-Level Value. By combining state-of-the-art CNC machining with permanent mold casting expertise, Premier Aluminum ensures that every part is manufactured to the highest standard of precision, durability, and performance.
