At the C.A. Lawton Co., our team of customer advocates receives similar questions about our capabilities, metrics, and processes from current and prospective clients. 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 Lawton produce?
- Lawton 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 Lawton?
- Lawton 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. Lawton’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 Lawton pour?
- Lawton produces castings ranging from 400 to 15,000 lbs.—and sometimes even heavier, depending on the part geometry. Lawton will also take on smaller castings if they are part of a larger package.
How many furnaces does Lawton have?
- Lawton’s facility houses two electric furnaces.
Does Lawton heat treat?
- To provide our customers with castings that meet and exceed requirements in terms of mechanical properties, Lawton utilizes a heat treat partner to provide a full range of heat treat capabilities.
