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.

Semi-Permanent vs. Sacrificial Mold Release: When to Switch
Sep 24, 2026, 10:13 AM by Tom MalesicIf you are deciding between semi-permanent mold release and sacrificial mold release, you are really choosing how much of your production time goes toward reapplication versus pulling parts. Both approaches work. But only one fits your process, your mold, and the volume of parts you need to run each shift. Understanding what separates the two can help you reduce scrap rates, improve part finish consistency, and stop losing cycle time to interruptions that don't need to happen.Full story -
How to Choose the Right Mold Release Chemistry for Your Molding Process
Sep 11, 2026, 10:26 AM by Tom MalesicFull storyIf 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 MalesicYour 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.Full story
