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.”

  • How to Choose the Right Mold Release Chemistry for Your Molding Process

    Sep 11, 2026, 10:26 AM by Tom Malesic

    If parts are sticking, tearing, or requiring more applications than they should, the product may not be the problem. The chemistry might be. Matching mold release chemistry to your specific process, substrate, and production demands is one of the most consequential decisions you can make on the production floor. Get it right, and your cycles run cleaner, faster, and more consistently. Get it wrong, and you spend your shift chasing problems that compound with every pull.

    This guide walks you through the key variables so you can evaluate your options with clarity and confidence.

  • Mold Release for Polyurethane: What Changes When You Scale to Production

    Aug 24, 2026, 15:44 PM by Tom Malesic
    Your trial runs went well. Parts released cleanly, the team was confident, and the process looked solid. Then you moved to full production volume, and things started to shift. Parts stuck more often. Mold buildup accumulated faster than expected. Scrap climbed.

  • Mold Release for Thermoset Materials: Reducing Defects and Improving Yield

    Jul 27, 2026, 16:21 PM by Tom Malesic
    If you run thermoset molding operations, you already know that release performance is not a minor variable. It directly affects part quality, cycle time, and how often your team is stopping to clean molds, rework parts, or discard material that should have come out clean the first time.
