Our Story

Built to make overseas manufacturing easier

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

After the Section 301 (China) tariffs began in 2018, Redstone expanded its options so customers could manage tariff exposure. While manufacturing in China remains a strong fit for many parts, much of Redstone’s demand is now for production in Mexico.

Market Shifts

Adapting as the sourcing map changes

The international manufacturing landscape is changing. With rising wages in China and unpredictable tariffs, U.S. companies are shifting production with a more diverse sourcing strategy. Finding reliable, responsive manufacturers abroad is hard, that is where Redstone helps.

With production across Mexico and China and consistent U.S. engineering oversight, our team makes it quick and cost-effective to place or move a program to a new facility while reducing the risk involved.

U.S. Engineering Oversight

Local production, American quality

With a U.S. facility in Seattle, Washington and local staff in Mexico and China, Redstone produces metal castings, fabricated parts, and machined metal parts. Our team of engineers reduces the headaches and risk of working in a new country. We are here to make your job easier.
