Green Sand Aluminum Casting
In this casting process, the term “green sand” refers to the use of tempered water to activate the clay in the sand. It binds the sand mixture in the mold long enough to form the casting foundation, then the chosen aluminum alloy is poured into the mold to create the part. With this process, Pentz Cast Solutions can deliver castings that feature a superior finish compared to traditional molds, and as-cast finishes exceeding the industry standard.

Green Sand Aluminum Casting Value-Added Services
At Pentz Cast Solutions, we provide value-added services for development, machining, and finishing to ensure your finished product aligns with your project specifications:
In-House Casting Development
With the entire casting development process performed in-house, each stage is monitored by a skilled Pentz representative. We offer reduced turnaround times through fast-track engineering and repeatable CNC machining, allowing us to make time for additional services in post-production.
Casting Machining
Our capabilities include 3-, 4-, and 5-axis CNC machining equipment and the use of CAD/CAM/CNC software, allowing us to perform custom machining services for your finished product. These services can achieve intricate detailing for prototypes and part marking for high-volume production to meet your specific requirements.
Casting Treating
To increase the hardness, strength, and corrosion resistance of a specific casting or component, we offer chemical treatment, coating, and anodizing services, as well as heat treatments, to add longevity to finished products:
- Chemical Treat—clear and yellow chromate
- Anodizing—Clear, hard, colors
- Coatings—Wet paint and powder coat
- Hot Isostatic Pressing (HIP or ‘Hipping’)
Casting Finishing
For almost any casting project, we can create extraordinarily smooth, detailed castings with a 0.150 RMS finish, utilizing the following processes:
- Vibratory Finishing
- Polishing
- Chrome Plating
- Specialty Blasting
- Texturing
- Bead and Sand Blasting
