UBW’s Keystone Foundry Division
Precision Bronze Casting Since 1887
Advanced Casting Processes
At United Brass Works, our Keystone Foundry Division produces high-performance brass and bronze castings that meet the rigorous demands of modern industries. We combine traditional foundry practices with cutting-edge technology to deliver precision castings for a variety of applications, including industrial, fire protection, and custom-engineered solutions.
Our foundry is equipped with advanced tools and processes that ensure the highest level of quality control from start to finish.
We utilize a range of sophisticated casting techniques that ensure both consistency and dimensional accuracy in every part we produce:
- Inductotherm Melting Furnaces: Our coreless and channel furnaces ensure that molten metal is at the correct temperature for casting, delivering high-quality brass and bronze components with consistent composition.
- Hunter HMP10F Automatic Molding System: This system automates the molding process, ensuring repeatable accuracy and reducing the margin for error. The result is high-quality castings that meet exact specifications, time after time.
- Sand Control: Our Belloi & Romagnoli Sand Mixer works alongside a full sand lab with automatic moisture control to ensure that every mold is produced under optimal conditions. This control guarantees consistency in each casting, minimizing the risk of defects.
Sand Preparation
Our sand preparation system produces high-quality sand mixes, ensuring superior mold strength and casting accuracy.
Pattern Shop
Our pattern shop designs and produces precise patterns to create accurate molds, ensuring flawless casting results for your project.
Melting
Our state-of-the-art melting process ensures precise alloy compositions and consistent quality, delivering exceptional performance for every casting.
Core Making
Using advanced core making techniques, we create highly accurate cores that meet the exact specifications of even the most complex designs.
Molding & Pouring
Our precision molding and pouring process guarantees strong, reliable castings, tailored to meet your exacting requirements.
Cleaning Room
In our cleaning room, we use modern techniques to remove excess material and refine each casting, ensuring a perfect finish.
Pollution Control Equipment
We are committed to sustainability with cutting-edge pollution control equipment that minimizes environmental impact during production.
Full-Service Foundry For Your Casting Needs
There’s more to being a foundry than pouring metal. Our Keystone foundry division produces high-quality, pressure tight castings in a variety of red brass alloys such as CDA 836, CDA 844 and CDA 922, as well as aluminum bronze, manganese bronze and a variety of lead-free alloys.
Our capabilities include pattern equipment design, stereo lithography and solid modeling. Our in-house pattern and tool shop enables on-site repair, maintenance or modifications to both matchplates and core boxes. We also offer complete machining capabilities, pressure testing and impregnation services.

Quality Assurance at Keystone Foundry
Our commitment to quality does not stop at the casting process. We employ multiple quality assurance measures to verify that each casting meets the necessary standards:
- Dimensional Accuracy: Using tools like the Browne & Sharpe Global Image 777, we verify the dimensional accuracy of every casting to ensure it meets customer specifications.
- Material Testing: We utilize specialized equipment to test the composition and hardness of our castings, ensuring that they perform as expected in their final application.
- Surface Finish Testing: We use shot blasting, grinding, and surface finish testing to guarantee that every part meets the required finish, making it ready for immediate use in industrial systems.
