Aluminum Castings for Electrical Components

Aluminum Casting Solutions for Electrical Equipment

Electrical equipment manufacturers rely on aluminum castings for their lightweight properties, corrosion resistance, and excellent thermal conductivity. Watry produces aluminum castings engineered to perform reliably in electrical environments that require heat dissipation, enclosure protection, and precise dimensional control.

Common electrical components include:

• Electrical enclosures and housings
• Transformer and power distribution components
• Heat sinks and thermal management parts
• Junction boxes and control housings
• Motor housings and end bells
• Structural supports for electrical assemblies

Watry’s aluminum casting processes are designed to ensure repeatable quality, tight tolerances, and consistent metallurgical properties across production programs.

Advanced Casting Processes for Electrical Components

Watry applies proven aluminum casting methods to meet the technical requirements of electrical applications:

Permanent Mold Aluminum Casting

Permanent mold casting produces dense aluminum components with excellent surface quality and dimensional stability. This process is well suited for electrical housings and components requiring consistent wall thickness and dependable performance.

Semi-Permanent Mold Casting

Semi-permanent mold casting supports complex electrical components by incorporating sand cores for internal features while maintaining the strength benefits of permanent mold casting.

Tilt-Pour and Reverse Tilt-Pour Casting

Tilt-pour and reverse tilt-pour processes reduce turbulence and improve metal flow, resulting in improved surface finish and reduced porosity. These processes are ideal for electrical components that demand reliable structural integrity and consistent heat dissipation.

Integrated Machining and Process Control

Watry’s electrical aluminum castings are supported by comprehensive in-house CNC machining and finishing capabilities, allowing components to be produced and finished within the same facility. This integration ensures dimensional accuracy, consistent quality, and faster feedback between casting and machining operations.

In-house process control includes:

• CNC machining and finishing
• Dimensional inspection and validation
• Metallurgical analysis
• Leak testing and functional verification

By maintaining full process control, Watry delivers electrical aluminum components that meet stringent OEM and regulatory requirements.

Single-Source Manufacturing for Electrical OEMs

As a fully integrated aluminum foundry, Watry provides electrical equipment manufacturers with a single-source production partner. Tooling, casting, machining, finishing, and testing are all performed in-house, reducing complexity and improving supply chain reliability.

Benefits include:

• Reduced lead times
• Fewer suppliers to manage
• Improved quality consistency
• Faster response to design changes
• Lower total cost of ownership

This approach allows electrical OEMs to maintain consistent production schedules and reliable component quality.

Production Scale and Versatility

Watry supports a wide range of electrical production programs, from low-volume specialty components to high-volume OEM parts.

Capabilities include:

• Part weight range: 1 lb. to 150+ lbs.
• Annual volumes: 300 to 600,000 parts
• Materials: Aluminum alloys selected for strength, conductivity, and corrosion resistance
• Automation: Advanced casting and machining automation for repeatable, high-volume production

This flexibility enables Watry to support evolving electrical technologies and long-term production programs.
