Heat Treat Straightening & Dimensional Control Engineering Intern
About The Position
Wisconsin Aluminum Foundry is hiring a paid engineering intern for a 12–14 week summer placement in Manitowoc, Wisconsin, from May or June through August 2027. The intern will own a project focused on returning castings to specification after they move during heat treatment. Working with engineers and operators on the production floor, the intern will design and implement straightening processes, connect straightening decisions to machining results, and present measurable outcomes and recommendations to WAF leadership at the end of the summer. The project is expected to quantify scrap costs saved by reducing out-of-spec parts, time saved in heat treat and straightening per part or shift, and safety improvements. Wisconsin Aluminum Foundry makes aluminum, brass, and bronze castings for several industries and performs casting, heat treatment, machining, and finishing in-house.
