Precision Green Sand Molding Capabilities
The term “green sand” refers to the fact that temper water is used to activate the clay in the sand to bind the sand in the mold just long enough to build a mold, pour aluminum and build a casting with superior finish. Pentz Cast Solutions has the experience and capabilities required to create sand moldings for proto and or large scale production. Our innovative sand casting equipment can turn tight tolerances and offers high repeatability to save time compared to standard manufacturing processes. Our in-house capabilities ensure each component is manufactured by a dedicated, skilled Pentz machinist and tested to Pentz Cast Solutions’ trademark “as cast” surface finish.

Precision Automated Green Sand Molding
Automated green sand molding allows for superior performance, efficiency and cost-effectiveness on custom built moldings. “As cast” .150 rms finishes can be achieved with intricate detail and complex geometries and cored interior cavities. Our precision Sinto Automated Mold System can build a precision 600, pound sand mold every 60 seconds to build your castings very efficiently.
Machine Precision Green Sand Molding
In Pentz’s machine precision green sand molding process, our skilled technicians utilize programable controls to ultimately control the system sand when forming your casting. This results in the most versatile casting process available. The sand is recirculated and reused every few hours for efficient, ecologically sound molding. Our machines include Osborn 3161 and Osborn 3191 Molding Machines.
Precision Dry Sand Molding
Dry Sand molding enables molds to be made in multiple directions of mold sections and cores. Dry sand molding is ideal for creating castings with radical geometries such as deep pockets or thing ribs. Dry sand castings often require high strength and tight sealing characteristics. Tooling cost is relatively low, and we utilize a series of innovative dry sand mixers and equipment.
We utilize the Hall 3HXS PLC controlled permanent mold system to build higher quantity, high density castings. Permanent molding is generally used for larger castings or castings with annual quantity requirements of 5,000 to or more EAU. We can build prototypes for approval prior to mass production.

Pentz Cast Solutions’ Green Sand Molding Process
Highly skilled artisans carefully build precision green sand molds at Pentz Cast Solutions to produce the absolute best “as cast” finishes in the industry. Extraordinary smooth detailed castings with a .150 RMS finish are achieved by skilled technicians and a green sand mold system utilizing programable controls to manage system sand. Coring can be accomplished with aluminum shell core box tooling, dry sand core boxes or 3D printed sand cores depending on several factors like geometry, size and quantity. Green sand is recirculated and is used thousands of times, so it is very ecologically sound and very efficient.
We are always considering molds while collaborating with customers when developing cast solutions. This allows us to build parts efficiently with lower part costs. We utilize Highly engineered hybrid solutions to create intricate complex geometry in large proto and or production.
