AMAX Offerings
Amax Manufacturing Inc. is a family-owned plastic injection molding company based in Foley, Minnesota, specializing in high-quality and responsive service. With injection molding presses ranging from 55 to 350 tons, we accommodate a wide range of part sizes, materials, and production volumes. We can also use overmolding to mold metal threaded inserts or other components into your parts. Using efficient, sustainable, and flexible practices, Amax Manufacturing offers low cost, quality part production.
Beyond injection molding, we offer secondary services like hot stamping and assembly, ensuring that your products arrive ready for sale or further processing. Our team can also assist with labeling and packaging for a complete, hassle-free solution.
We are able to provide product design services in-house to bring your project from idea to production using our team.
3D Printing Services
We now provide 3D printing for prototyping, small-batch production, and custom orders. Whether you need help designing products, crafting unique branded items, or producing hard-to-find replacement parts, we can help. If a mold investment isn’t practical, we can 3D print low-volume products efficiently.
