Castings and Foundry Services
The Flowserve Dayton Foundry is a world-class, high alloy facility specializing in stainless steels, nickel- based alloys and reactive alloys such as titanium and zirconium. The foundry has the capacity to provide rapid prototyping through its investment and no-bake processes. Additionally, the Flowserve induction skull melting process is capable of producing reactive alloy castings at a significantly lower cost and with unmatched alloy flexibility.
The metallurgists and skilled trades people provide the expertise and know-how in casting design and technical assistance in the most demanding environmental applications.
The foundry's goal is to provide high-quality castings that require little or no machining before final assembly.

Melting
To melt steel, cast iron, brass and bronze materials, Flowserve Dayton Foundry is equipped with an unparalleled range of melting furnaces with capacities from 150 to 8000 pounds. Melt times are less than 60 to 90 minutes per heat. This exceptional capability enables the foundry to pour heat lots in any quantity and to meet a wide range of temperature requirements.
Pattern Shop
Flowserve Dayton Foundry is one of the few foundries nationwide that offers a complete in-house pattern shop that produces the precise patterns used in today’s high-performance molding processes. With this in-house flexibility, Flowserve Dayton Foundry produces outstanding castings that meet customers’ requirements. The Dayton foundry also maintains relationships with outside pattern shops that enhance tooling acquisition capability.
Alloy Expertise
Since 1912, Flowserve has been in the forefront of alloy development and foundry technology. A pioneer in the development of cast stainless steels, including Alloy 20 and CD4MCuN, Flowserve is committed to leadership in metallurgical expertise. Utilizing a unique combination of ceramic coremaking and molding, casting technology, heat treat control, radiographic and other non- destructive testing and analytical procedures, Flowserve produces castings of unsurpassed quality in not only stainless steels but various other high alloys. These include nickel-base and cobalt-base alloys, and reactive alloys such as titanium and zirconium (i.e., brand names such as Hastelloy®, Inconel®, Monel®, etc.).
Finishing
Finishing is the last crucial step in the casting process and Flowserve Dayton Foundry takes pride in upholding the highest standards for its customers. After the cast- ing is released from the gates and risers, it is cleaned and any burrs or blemishes are removed to produce the finished product. In addition to this finishing process, Flowserve also employs a quality assurance program to ensure the highest quality castings are produced.
Quality Assurance
To ensure castings meet customer expectations and requirements for quality, delivery and price, Flowserve employs a quality assurance program that involves several processes.
- While many foundries purchase “master melt,” Flowserve possesses in-house capability to blend and analyze metals. This assures consistent and optimal chemistry, corrosion resistance and mechanical properties.
- All operations are carefully controlled and documented through a series of technical specifications to assure consistency.
- Every heat is analyzed at least twice to guarantee compositional integrity.
- All castings are inspected to MSS Standard Practice 55.
Investment Process
Flowserve Dayton Foundry is renowned for its commitment to quality castings developed through its investment process, commonly known as lost wax casting. This process produces precise castings of unmatched geometric correctness, fine surface finishes, exceptional detail and tight tolerances. Flowserve lost wax castings permit economical design choices, keeping expensive finishing and machining operations at a minimum, or eliminating their need entirely.
Shell Process
Well suited to higher volume production where uniformity and consistency are required, the Flowserve Dayton Foundry’s Shell Process can routinely produce castings to ASTM Shrinkage Severity Level II. These castings are made in shell molds and have a superior surface finish and outstanding dimensional integrity. For larger production runs, this process can offer significant cost savings. The ultimate goal is to deliver high- quality castings while keeping expensive machining at a minimum or better yet eliminating it entirely.
No Bake Process
Flowserve Dayton Foundry's No-Bake Process can satisfy the most demanding requirements for high-quality, high-performance castings. Utilizing wood, plastic, styrofoam and metal patterns, no-bake is particularly appropriate for prototype work as alterations can be made cost effectively. It is also appropriate for one-offs, as well as high production runs.
Reactive Alloy
Flowserve is one of the few foundries in the United States to specialize in high-quality titanium casting as part of its Reactive Alloy Process. By utilizing the technological advantages of Induction Skull Melting with specially modified investment molding and rammed refractory processes, Flowserve Dayton Foundry can produce competitively priced, superior titanium castings.
Z Corp Process
Flowserve Dayton Foundry utilizes the Z Corp rapid prototype process. This process produces cast metal parts from a 3D CAD file faster and less expensively than many other available rapid prototype casting methods. With the Z Corp process, customers can take full advantage of the complete range of metal alloys produced at the foundry to have castings manufactured.
