We Are Growing!

Ermak Foundry & Machining and Northwest Casting are excited to announce the acquisition of Patriot Foundry & Castings of Franklin, New Hampshire (www.patriotfoundry.com). This acquisition expands Ermak’s capabilities to include brass, bronze, and zinc castings, in addition to adding ISO-9001 and NIST 800-171 certifications. The new location will serve as our New England/East Coast base of operations as we continue to expand across the country. More details to come!

Our Capabilities

Ermak provides everything from prototypes to one-off custom products to large production runs. We specialize in permanent mold (also known as gravity-fed die cast), green sand, and air set (also known as no-bake) castings as well as many value-added services such as finishing, machining, and heat-treat.

We are a one-stop shop for finished, precision cast aluminum parts. Our management team can assist with product and market development, whether you sell direct, through big-box retail, or via distribution. We use certified aluminum ingot – 319, 333, 356, A356, 535, & 713 – and utilize flask/die sizes from 12″ x 14″ to 60″ x 60″. 

Our production runs range from one to tens of thousands and from ounces to hundreds of pounds, always at a high tolerance for original equipment manufacturers in the following broad categories: industrial, recreational, construction, utility, and agricultural companies throughout the world. 

ERMAK Foundry and Machining Mold

Permanent Mold

Our variety of permanent mold, gravity-fed die casting machines offer the flexibility and capacity for production runs large and small, with tighter dimensional tolerances and a superior surface finish over sand castings, making for a great alternative to expensive high-pressure die cast processes

Sand Casting

We have both green sand and air set (no-bake) casting capabilities, allowing for cost efficient tooling and parts from low- to high-cost, simple to extremely complex, and small to very large.

Our finishing process includes taking cooled, molded cast assemblies and preparing them for use. Depending on the casting type, finishing may take several steps or processes on our in-house equipment.

We utilize a proprietary process that allows us to turnaround a 3D CAD file to “95% accurate” casting prototypes in roughly a week. We also work with partners where we can “print” a sand pattern that will give you a production accurate part, typically in a few weeks, saving you valuable development time and money.
