Prevent Demolding with Mold Release Sealers
While you may be using a mold release agent to prevent demolding issues, such as sticking and part appearance, you could be missing an important step if you’re not using a mold sealer first.
The reason? Molds expand and contract during the thermal changes of each production cycle, causing extremely small cracks to form. Eventually the resin begins to penetrate these cracks, resulting in part and mold damage.
Properly sealing your molds before applying a mold release agent creates a protective barrier, bonding to the mold surface, filling in the microporosity, and providing an ideal surface for mold release bonding.
At Stoner Molding Solutions, we’ve developed a variety of mold sealers for a wide range of production applications.
