Our Molding Heritage
We Specialize in Release Agents
Since 1942, Stoner Molding Solutions has been known for superior performance and consistent quality. Molders have come to rely on Stoner’s world class service and expert solutions for the challenges facing their business.
Today, Stoner’s brand portfolio offers solutions for any molding process. If you can mold it, we can release it. Stoner manufactures molding solutions for the thermoplastics, polyurethanes, composites, rotational, rubber, fiber, and investment casting industries.
Stoner release agents yield better performance than any competitive product. If you have not experienced the Stoner difference, please consider these reasons to switch. With Stoner, your cost per released part will be lower than any competitive product, so you’ll get “More Parts in Less Time.”
In the 1950s, Stoner was an early innovator of aerosol technology.
1950sIn the 1960s, Stoner’s success with lubricants for rubber molding led to the development of release agents for thermoplastic injection.
1960sBy the 1970s, Stoner expanded into polyurethane molding solutions.
1970sDuring the 1980s new cleaners and rust preventives were added.
1980sIn the 1990s, Stoner developed products for investment casting and melt spinning of polyester and nylon fiber.
1990sIn 2000, Stoner purchased Zip Molders Edge products.
2000In 2006, Stoner acquired the Dwight Products Nix Stix line for polyurethane and rubber molding.
2006In 2008 Stoner acquired the Releasomers line for rubber, composites, and rotational molding.
2008In 2013, the TraSys brand for rotational, rubber, and composites molding was added.
2013Honey Wax and KantStik brands for composites molding were added in 2014.
2014In 2018 M8 Miracle Gloss paste waxes were added for the composites market.

Purging Compound Guide: How Smart Purging Compounds Keep Production Moving
Mar 2, 2026, 13:02 PM by Tom MalesicProduction floors do not slow down just because a machine needs cleaning. When resin changes, colors shift, or carbon buildup begins to creep into the barrel, the clock keeps ticking, and every minute spent troubleshooting defects or manually cleaning equipment costs money. That is why having a clear guide to purging compounds matters. The right purging approach can mean the difference between smooth production flow and an entire shift lost to scrap, quality issues, and unplanned downtime.Full story -
Which Formula Delivers the Best Mold Release Performance? A Mold Release Comparison
Mar 2, 2026, 12:43 PM by Tom MalesicFull storyIn many manufacturing environments, mold release agents are treated like a routine supply. If the current product “works,” it stays in rotation. But when cycle times drift upward, parts start sticking, or surface finish becomes inconsistent, teams often discover that the mold release agent was never a minor variable at all. It was the hidden driver behind quality issues, downtime, and unnecessary cleaning.

What Role Does Surface Preparation Play in Part Quality in Industrial Composite Molding?
Jan 28, 2026, 13:18 PM by Tom MalesicFull storyIn industrial composite molding, quality issues rarely start with resin selection or fiber architecture. They begin much earlier, at the mold surface. Even in well-controlled production environments, inconsistent surface preparation quietly undermines resin flow, part release, dimensional accuracy, and surface finish. The result is often not a single dramatic failure, but a pattern of inefficiencies. These lead to scrapped parts, extended cycle times, difficult demolding, and gradual mold degradation.
