Redstone Manufacturing - Metal Casting and Machining


Redstone Manufacturing has been providing metal castings and machined parts since 2018. Redstone’s President Eric Millinger started in international manufacturing as a Supply Chain Manager in the agricultural machinery industry. After successfully outsourcing to China, Eric saw how difficult international manufacturing can be and started Redstone Manufacturing to help US-based companies navigate the process.

After the the Section 301 Tariffs (China tariffs) began in Summer 2018, Redstone focused on expanding operations to India and Mexico to provide tariff-free options for customers. While manufacturing in China remains a viable option for many parts, much of Redstone’s new demand is for manufacturing in India and Mexico.



The international manufacturing landscape is gradually changing. With rising wages in China and unpredictable tariffs, U.S. companies are now shifting their production out of China using a diverse portfolio of rapidly developing countries. Finding reliable and responsive manufacturers in developing countries can be tough. That’s why Redstone is here to help.

With a network of trusted manufacturing partners in India, Mexico, Brazil, Taiwan, and China and our engineering teams on the ground, we make it quick and cost-effective to expand your supply chain to new countries while reducing the level of risk involved.
