In-House Machining Solution

If you’re paying extra freight costs to ship castings from foundries to machine shops, or having quality struggles uncovering defects after machining, a foundry with in-house machining capabilities could be your solution. Stainless Foundry & Engineering (SF&E) has been machining castings since the mid-1980s. Having a fully dedicated off-site facility, owned and operated by SF&E, we give our customers the ability to work with a true one-stop shop. Located 15 minutes northwest of beautiful downtown Milwaukee, we possess a number of different CNC machines particularly lathes, horizontal machine centers, and vertical machining centers. Under that same roof, we top off our inspection capabilities with a reliable and robust CMM to verify dimensional inspection.

Our various different lathes possess the ability to rough and finish various geometries of castings up to 25” in diameter and 50” in length. Whether you’re looking for rough or tight tolerances, we can ensure our CNC engineering department dials in the programming required to meet your needs.


Horizontal & Vertical Machining Centers

Doing business in multiple industries calls for a wide scope of equipment needs. To satisfy our customers, we have various horizontal machining centers (4-axis) capable of handling castings up to 51 x 43 x 49 (L x H x W) inches and various vertical machining centers capable of handling 40 x 21 x 21 inches.

Many machined castings require more thorough inspection so we’ve equipped our shop with a Brown & Sharp Xcel 9x12x9 CMM with fully functional probes and software updated to 2021 standards. Our inspection team has recently calibrated and certified our equipment to meet industry standards to ensure our customers get the quality they want, and have come to expect, from our world-class organization.

Machine Shop


Our primary focus is on low-volume, complex machining, however we have developed a partner network with 8 local machine shops to help us satisfy our order requirements. All of our partners are fully audited before they are added to our approved vendor list. Whether you’re looking for 1 casting or 35,000, SF&E is poised to handle some of most vigorous and difficult machining in the industry. Our lean manufacturing systems allow us to control costs through efficiencies and reduced lead times so our customers can benefit from high quality, low cost speed to market products.

Supporting the Global Defense Supply Chain

All major weapons systems contain a metal casting. Stainless Foundry & Engineering works with different alloys and techniques to produce castings that are better equipped to support the defense industry needs, anywhere from submarines to advanced weapons systems.

High Spec Castings – What You Need to Know about Testing

Parts produced for the nuclear, petrochemical, power generation, military, and defense industries require a high level of specification. Thorough testing is imperative to ensure these critical castings not only meet customer and industry standards, but they have the structural integrity to perform throughout their expected service life. Here’s how we do it.

Anatomy of a Pour: Investment Casting Photo Story

When Stainless Foundry & Engineering (SF&E) opened its doors in 1946, we specialized in sand casting, primarily producing impellers for pumps. SF&E added investment casting to its service offering in 1968 in response to the increasing demand for precision parts. We’ve documented our investment casting process in a series of photos as a way to pay homage to this practice, which dates back to 3,000 B.C.
