LeClaire Manufacturing serves a wide range of industries around the world. Regardless of their fields, our customers continue to be industry leaders and innovators by focusing on their final product — instead of worrying if their aluminum casting provider is producing good parts for making that product. 

Our customers confidently leave the casting and machining portion of their products to us. With our extensive casting and machining experience, our complex core making and assembling capabilities, and our dedication to exceeding customers’ needs, we produce the highest-quality, porosity-free, pressure-tight sand and permanent mold castings — machined complete.
