The C.A. Lawton Co. FAQs

By C.A. Lawton | November 10, 2015

At The C.A. Lawton Co. (Calco), our team of customer advocates hears similar questions about our capabilities, metrics and processes from many current and prospective clients. And with our blog being built to serve as an educational resource for readers, we’d like to answer some of these common questions in today’s post:


What kind of castings does Calco produce?

  • Calco pours gray iron and ductile iron castings. We are also proficient in running low temp ductile and austempered castings.

What casting methods are available at Calco?

  • Calco uses a no-bake airset sand casting process. Using this airset method, sand molds are created using a foam, wood or urethane pattern. Sand is then mixed with a catalyst and binder using a high-speed mixer. It is then discharged into a flask enclosing the pattern, gating, risers, and chills. The mixture hardens, and the mold is removed from the pattern. Calco’s airset method creates molds with outstanding dimensional strength. It is one of the most cost-effective and advanced sand casting processes available.

What size castings can Calco pour?

  • Calco produces castings ranging from 400 to 15,000 lbs.—and sometimes even heavier, depending on the part geometry. Calco will also take on smaller castings if they are part of a larger package.

Does Calco heat treat?

  • In an effort to provide our customers with castings that meet and exceed requirements in terms of mechanical properties, Calco utilizes a heat treat partner to provide a full range of heat treat capabilities.
