How often are your molded goods getting stuck in their molds? Or worse, how often are your composite molded products damaged during the demolding process? One of the greatest tools for preventing product error is a mold sealer. A high-quality mold sealer will ensure that your finished goods are released far more easily and with less damage.

Create a Smooth and Clean Surface with Mold Sealers

When you look at your steel or plastic mold, you might think you see a perfectly smooth and clean mold surface – but how certain are you? The reality is that a surface that looks smooth and unmarked to the naked eye could have millions of tiny pores and cracks within the mold surface.

These imperfections are only made deeper and wider when the heat of production causes expansion and contraction within the mold. These micropores can ‘grab’ your finished goods and cause a difficult release – but a sealer can fix this and help you meet customer demands.

Specifically formulated for the composite molding industry, a mold sealer coats and protects the surface of your mold. This coating helps fill in the micropores, holes, scratches, and other tiny flaws that cause your production troubles. A mold sealer prevents vacuuming, gripping, and general sticking issues, particularly when used with a mold release product. Industrial mold processes must be fast and efficient, which is far easier to achieve when using our industrial molding products.

Benefits and Advantages of Using a Mold Sealer

While you might think your process is as good as it gets, we want to show you how much your molding cycles can be improved just by using a mold sealer.

Improved Surface Finish

When your composite mold needs to create a fine surface with a smooth finish, a mold sealer is the best way to ensure that there are no sticking or poorly molded sections. A sealer becomes even more important when you are creating specifically textured surfaces, as a sealer can help with cleaner surface details.

Faster Molding Cycles

Because of the micropores and other small cracks in the surface of your mold, you might notice a worse buildup of dirt and grime throughout multiple molding cycles. With a combination of mold sealer and mold release, your quality control process can be sped up and made much more efficient!

Improved Release Agent Performance

A mold sealer prevents buildup and provides faster cleanup of release agents, dirt, oil, and grime, which might cause issues throughout multiple molding cycles. Mold sealers and mold release agents are designed to be used together, so contact our team to learn more about how to make the most of both products!

Higher Productivity and Profitability

All of these combine to create a more efficient and agile manufacturing environment that will increase your sales and reduce waste! When you aren’t tossing out a portion of your large and small batches of product, you will enjoy an improved bottom line and more profitable business!
