Metal Casting Services
Midwest Metal Products offers a full-scale metal casting service based in Winona, Minnesota. With decades of experience in foundry work, the company provides engineered castings for industries such as mining, oil and gas, energy, trenchless construction, and more. Projects are handled under the guidance of a dedicated metallurgist, allowing for material selection, process control, and quality verification from start to finish.
What is Metalcasting?
Metalcasting is a process in which molten or liquid metal is poured into a mold made of sand, metal or ceramic, to form geometrically complex parts. The most common metals used for metalcasting include iron, aluminum, magnesium, zinc, steel and copper-based alloys. Metal castings are found in cars, trucks, planes, trains, mining and construction equipment, and kitchen appliances to name only a few examples. Because castings play such vital roles in our daily lives, we know that it is incredibly important for our products to be dependable. With Midwest Metal Products you never have to gamble with the quality of your metalcasting because our teams have a vested interest in our clients’ successes. As a trusted metal casting service, we take pride in delivering long-term value through precision and consistency.
Sand Casting: A Proven Manufacturing Method
The company specializes in sand casting, one of the most established methods for producing metal parts. This process uses sand molds to shape molten metal into functional components. It is especially effective for parts with complex geometries, short production runs, or those requiring rapid design changes.
Midwest Metal Products applies sand casting to produce items such as pump housings, impellers, bearing supports, and other mission-critical parts. The method supports various sizes and weights, with castings reaching up to 1,100 pounds for steel and 1,500 pounds for iron.
The foundry’s sand casting services include every stage of the process. In-house capabilities cover pattern creation, mold and core preparation, melting, pouring, cooling, and cleaning. Once solidified, castings are processed through finishing steps such as gating removal, grinding, and inspection.
The facility is equipped to handle both simple and intricate casting projects. Whether the request involves just one or two parts per year or recurring production runs, Midwest Metal Products can adjust its processes to meet a wide range of timelines and volumes.
Heat Treatment and Final Processing
In addition to casting, Midwest Metal Products provides heat treatment and post-processing operations. Available treatments include annealing, quenching, tempering, and case hardening. Final touches, such as machining, painting, and assembly are handled by valued regional partners to support complete delivery.
A metallurgist is involved in each stage to help meet dimensional, mechanical, and surface finish requirements. This direct involvement supports better communication and performance outcomes for critical applications.
Reduce Parts Count AND Add Value With Midwest Metalcasting Expertise
One major way we help our customers succeed is by offering casting solutions that reduce part counts and add lasting value to their products. Many manufacturers rely on welded assemblies, known as ‘weldments,’ which require significant manual labor and can create bottlenecks in production. Keeping every component stocked is another constant challenge; when parts run out, the delays and costs of cutting from plate or pipe quickly add up. On top of that, the industry is facing a growing shortage of skilled labor.
By converting weldments into single-piece sand castings, you not only simplify your supply chain but also free up your skilled workforce to focus on higher-level tasks. That shift improves productivity across the plant and gives your most experienced team members more meaningful, satisfying work. If you’re facing these issues, there’s a good chance you’ve come to Midwest Metal Products for exactly the kind of sand casting solution we specialize in.
Our engineers have learned that just as integrated circuits or ‘chips’ decrease the parts count, add value, and improve the reliability of electronics, castings are the answer to earn the same benefits. Trust the most reliable, detail-attentive hands in the business and hire Midwest Metal Products for all of your sand casting services.
