Aluminum CNC Machining Wisconsin

For manufacturers across Wisconsin and the Midwest, precision machining is essential to product performance, consistency, and reliability. Since 1988, Premier Aluminum LLC has delivered high-quality aluminum CNC machining solutions from its Racine, Wisconsin facility, supporting OEMs and industrial manufacturers with tight-tolerance, production-ready components.

As a fully integrated permanent mold aluminum foundry and machining partner, Premier Aluminum combines advanced CNC machining capabilities with in-house casting, tooling, finishing, testing, and assembly. This vertically integrated approach allows us to maintain full control over quality, lead times, and dimensional accuracy while providing cost-effective machining solutions for low- to medium-volume production.

From complex housings and structural components to precision-machined assemblies, our aluminum CNC machining services in Wisconsin are designed to meet demanding specifications across a wide range of industries.

Premier Aluminum provides full-service aluminum CNC machining in Wisconsin, supporting OEMs and manufacturers that require tight tolerances, repeatability, and production-ready components. As a trusted Wisconsin aluminum foundry with integrated machining operations, we deliver precision CNC solutions that align directly with high-volume and low- to medium-volume manufacturing needs.

Our CNC milling capabilities support complex geometries, multi-face machining, pockets, slots, contours, and precision features. Using advanced horizontal and vertical machining centers, Premier Aluminum delivers consistent dimensional accuracy for structural components, housings, and precision assemblies.

Premier Aluminum operates extensive CNC turning capacity to machine cylindrical and rotational aluminum components with tight concentricity and surface finish control. This capability supports shafts, housings, bores, and round features critical to performance-driven applications.

We provide precision drilling, tapping, and threading operations to meet exact fastener, mounting, and assembly requirements. These processes ensure accurate hole placement, strong thread engagement, and repeatable results across production runs.

For components requiring tight internal tolerances, Premier Aluminum performs precision boring and reaming to achieve exact diameters, alignment, and surface finish. These operations are essential for bearing fits, mating components, and high-performance assemblies.

Our CNC machining processes emphasize controlled flatness, parallelism, and surface finish to ensure proper part fit and function. Maintaining flatness and surface integrity reduces secondary operations and supports consistent assembly performance.

As a trusted Wisconsin aluminum foundry, Premier Aluminum integrates CNC machining directly with permanent mold and semi permanent mold casting. This approach produces dense, dimensionally stable near-net-shape components that reduce machining time while supporting complex internal features and consistent material quality.

Our in-house engineering and tooling teams collaborate early in the design phase to optimize components specifically for CNC machining. This support improves dimensional stability, reduces cycle times, and enhances overall manufacturability.

Premier Aluminum verifies CNC machined aluminum components using CMM inspection, laser scanning, helium leak testing, pressure decay testing, and x-ray inspection. These quality controls ensure dimensional accuracy, flatness, and structural integrity.

Premier Aluminum produces a wide range of aluminum CNC machined components, including:

• Precision housings and enclosures
• Mounting brackets and structural supports
• Machined bases and frames
• Valve bodies and fluid handling components
• Motor housings and drive system parts
• Electronic and thermal management components
• Multi-part machined assemblies

Each component is manufactured to meet exact specifications for dimensional accuracy, strength, and repeatable performance.

Our cross-industry experience allows us to apply proven machining strategies, process control, and design expertise to every project we support.

With more than 35 years of experience, Premier Aluminum delivers reliable aluminum CNC machining solutions backed by deep manufacturing knowledge and consistent process control.

By combining casting, CNC machining, finishing, testing, and assembly under one roof, we reduce complexity, improve quality control, and shorten production timelines.

Our engineers work directly with OEMs and procurement teams to optimize designs for manufacturability, cost efficiency, and long-term performance.

Our Racine, WI facility includes:

• 23 Horizontal Machining Centers
• 18 Vertical Machining Centers
• 31 Lathe Turning Centers
• 19 Casting Stations
• 4 Coordinate Measuring Machines
• 1 Laser Scan System
• Extensive melt capacity

This advanced infrastructure enables us to support complex machining programs with precision and repeatability.

Advances in manufacturing technology can improve the efficiency, precision, and capabilities of modern machining operations. Argonne National Laboratory’s Advanced Manufacturing and Materials research supports innovations in advanced manufacturing that can contribute to improved industrial processes and material applications.

Located on a 9-acre site with a 200,000 sq. ft. foundry and 4,500 sq. ft. office, Premier Aluminum provides American-made quality and dependable manufacturing solutions established since 1988.

When precision, consistency, and integration matter most, trust Premier Aluminum LLC for Aluminum CNC Machining in Wisconsin. Our advanced machining capabilities, permanent mold expertise, and full-service manufacturing approach deliver results you can rely on.
