Our Molding Heritage

old-building

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.

  • 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.

  • AI in Manufacturing Process Optimization: How It Is Changing Mold Release Formulation

    Jul 10, 2026, 11:24 AM by Tom Malesic
    If you manage a production floor that depends on consistent molding output, you already know how quickly small inefficiencies add up. Inconsistent release performance across shifts, formulations that break down under high-cycle conditions, and cleaning routines that cut into uptime. Each one chips away at your throughput and your margins. AI in manufacturing process optimization is beginning to change how manufacturers address exactly these challenges, and the impact on mold release performance is worth your attention.

  • How Do You Achieve Consistent Release in Composite Molding?

    Jun 26, 2026, 11:12 AM by Tom Malesic
    Your results in composite molding are only as reliable as the process behind them. Consistent release does not happen by default. It takes careful mold surface preparation, the right products, and a procedure that your entire team can execute consistently, shift after shift.
