What We Do –
Our Grey Iron Casting Process
Tooling and Patterns
We can help you turn your casting needs into reality by starting with your print and creating the tooling you will need to cast the finished part, or by utilizing existing tooling. We also offer pattern storage on-site for your convenience.
Green Sand Molding
Molds are produced using 14”x19” and 20”x24” automatic, green sand molding machines. We run three molding and pouring lines simultaneously which are supplied with molten iron from our 7,000 pound induction furnaces.
Cores are used in the casting process to make the interior shape and design of the casting. Shell cores are made on-site in our core department. No bake and cold box cores are provided through our contracted core suppliers.
Castings are shot-blasted to remove left-over sand from the molding process then sent to our grinding department where parting lines and excess iron are removed. Each casting is carefully inspected and packaged for shipment. Castings are shipped in a large cardboard box on a pallet, but customized shipping is available upon request.
Why Choose Lemfco?
Generations of Knowledge
Our gray iron casting foundry is a fifth-generation owned and operated family business. That means our knowledge of the casting industry extends beyond the teachings of a classroom to knowledge that has been passed down, and added to, across five generations. Castings aren’t our job – they are our life.
The metal casting industry is the fourth largest contributor to the recycling economy. We purchase hundreds of thousands of pounds of steel and iron scrap each year. Our sand is continuously used, reconditioned, and re-used as long as possible. Once the sand has reached its useful life for casting, we have a beneficial re-use permit so the sand can be recycled for other uses. We are also currently exploring the addition of solar panels to our operations.
