Small Investment Casting Specialists
AMT is the leader in small, intricate, Precision Investment Castings. We specialize in castings that fit comfortably in the palm of your hand. In fact, our average cast part weight is under half a pound. While we do cast some products up to 5 pounds, the majority of our castings range from 0.002 pounds (less than a gram!) to 2 pounds. Our size envelope ranges from 0.25” through 10”.
Surface Finish and Complexity:
Although our castings are small, our capabilities are huge! Even the smallest casting that we manufacture has intricate details and features. Our niche focuses on castings with fine details, wall thicknesses as low as 0.020”,features such as blind holes and complex cored passages as well as exacting tolerances and stringent specifications. We achieve all of this while maintaining excellent surface finish of 60 – 125 RMS.
Dual Molding Processes:
AMT is unique in offering two distinctly different molding processes. This expertise allows us to select the best process to meet your requirements. In addition to our fully robotic ceramic shelling department, we also manufacture castings using the solid mold process. We can harness the benefits of vacuum solid molding to offer you near net-shape castings that cannot be traditionally produced by shell molding. See our Unique molding processes.
Alloys and Markets:
We cast these small, complex castings from a full range of air melt alloys including Nickel, Cobalt, Aluminum and Copper based alloys as well as Stainless and Low Alloy Steels. Our precision investment castings are used across a broad range of critical applications in all key markets including:Aerospace, Power Generation, Medical, Industrial, Defense, and others.
