Processing is controlled by custom software developed by Smooth-On’s IT department. Batch production is now completed in less than ½ the time. In addition to producing hundreds of proprietary products, Smooth-On toll manufactures custom formulations for private label clients around the world.

As Smooth-On introduces dozens of new products every year, the new lab combined with increased production capacity will reduce development time and allow the company to bring products to market faster and more efficiently.

People come from all over the world each month to attend Smooth-On materials seminars and learn the basics of mold making and casting as well as what these materials can do for a variety of applications.

Smooth-On Vice President, Clay Western, says that, “when we built our Easton factory in 1997, we projected that it would last for at least 20 years before we would need additional space. Due to double digit growth year after year, we found ourselves in need of additional production space 10 years later. After two additions, we could not physically add any more space and decided to move to a space that could accommodate our anticipated long-term growth requirements. We will continue operating 3 production shifts at the new facility that run 24 hours/day, six days a week to meet demand for our products”.
