We do prototypes, one-off custom products, and large production runs. ERMAK also provides product and market development assistance, whether you sell direct, through big-box retail, or via distribution.

Located in the Minneapolis suburb of Chaska Minnesota, ERMAK’s aluminum foundry and machine shop are housed under one roof creating an environment with a focus on efficiency, cost savings and quality control. Our employees have a thorough understanding of the entire product life cycle, from inception to production. Both shops work closely together and with outside vendors to produce machined castings of the finest quality.

FOUNDRY— We use certified aluminum ingot—319, 356, A356, 713 &535 and accommodate flask sizes 12" x 14" up to 45" x 45". We handle runs of one to tens of thousands of pours, ranging from ounces to hundreds of pounds.

MACHINING— Our machine shop is equipped with CNC Lathes, CNC Vertical Milling Machines and supporting equipment . We work with stainless steel, steel, aluminum, brass, plastic, and castings.

FINISHING— Our finishing process includes machining, heat treating, painting, anodizing, polishing, grinding, and plating.

PROTOTYPES— We provide cost analysis of patterns and guidance on how best to manufacture your product. For rapid prototyping, master patterns and/or match plates, we normally team with local, long-term vendors of ours, experts that will get your job done correctly with the highest efficiency.
