At Minncast, we specialize in precision steel sand castings — but that’s just the beginning of the story.
From concept to completion, we offer end-to-end manufacturing support that helps our customers bring complex metal components to life. Whether you’re in heavy industry, energy, defense, or transportation, here’s how Minncast adds value beyond the pour:
Airset Steel Sand Castings
We use traditional cope and drag patterns and coreboxes as well as advanced 3D sand printed mold and core components to produce castings in a wide range of sizes (up to 2,500 lbs) and alloys using airset (no-bake) molding, which is ideal for complex geometries and short-to-medium production runs.
Diverse Range of Alloys
- Carbon & alloy steels
- Stainless steels (austenitic, martensitic, duplex & super duplex)
- Nickel-base alloys & Ni-Resist (gray & ductile)
Pattern Tooling, solidification/flow modeling & CAD Design
From traditional patterns to 3D printed sand molds and cores, we support production and prototype development with full CAD & process simulation modeling. Gating designs are validated prior to tooling build using EKKcapcast to ensure first run success.
Heat Treatment
(3) in-house heat-treat ovens with water/polymer and oil quench capabilities. Furnaces are zone surveyed and certified. We utilize a network of regional heat treat shops for large parts and castings needing high temp (>2100 F) processing.
Machining
Our partners provide precision machining services to ensure castings meet performance and dimensional requirements. In addition to being able to supplying fully machined components, we can supply pre-machining and target machining services as well.
Finishing & Testing
- Shot blasting & grinding
- NDT, to include X-ray, magnetic particle & liquid penetrant testing.
- Primer and top-coat liquid painting
- Powder & Xylan coatings
- Passivation & electropolishing
Looking for a casting partner who does more than pour metal? We work best when we’re involved early — helping optimize designs, streamline costs, and shorten lead times.
