We Work with These Wisconsin Industries

Food & Beverage

Wisconsin is a leading producer of dairy, corn, soybeans, potatoes, and cranberries among the states. Mantz Automation helps keep America’s Dairyland running by manufacturing beverage bottles, food storage containers, and much more all with non-toxic molds that are safe for food production.


Wisconsin is a major producer of paper, packaging, and other consumer goods. Packaging can range from thin wall containers to sturdy bulk loads. Mantz Automation uses a variety of molding techniques to achieve these precise packaging definitions.


Known for exporting outboard engines and spark-ignition engine parts, Wisconsin companies even build world-class warships for the U.S. Navy. There is no room for error in this type of work. Mantz Automation is trusted to create perfect molds that produce the same component again and again without error.


Wisconsin is home to a very large and diverse manufacturing economy. Major companies like Harley Davidson, Caterpillar, Milwaukee Electric Tool Company, and the Kohler Company produce here. These companies know a machine is only as good as its parts, and those parts are only as good as the mold that made them. At Mantz Automation we produce the most reliable and precise molds in the industry.
