What Is Compression Molding?

Compression molding is a technique for shaping raw materials like rubber, urethane, and composites.  We’ll explore how EZ-Kote’s mold release agents contribute to streamlining compression molding workflows.

Understanding Compression Molding

Compression molding transforms raw materials, such as rubber, urethane, or composite materials, into different shapes and forms through the application of heat and pressure.

The process begins with raw material, typically pre-measured pellets or sheets, placed into a mold cavity. The mold is closed before heat and pressure are applied.

As the material softens under heat, it flows and takes the shape of the mold. Once cooled and solidified, the mold opens, revealing the finished product.

Applications of Compression Molding

Compression molding is used across various industries because it consistently produces high-quality, complex parts. We serve several of these industries.


Compression molding is widely used in manufacturing automotive components such as seals, gaskets, and O-rings.


The aerospace sector relies on compression molding to produce lightweight and durable composite parts used in aircraft interiors, structural components, and more.


Insulators, connectors, and housings for electrical equipment are often manufactured using compression molding, ensuring precise dimensions.

Consumer Goods

Compression molding creates a wide range of consumer products, from kitchen appliances to sporting goods, with consistent quality and durability.

This is where EZ-Kote’s expertise comes into play. Our specially formulated semi-permanent, water-based mold release agents are designed to facilitate easy release while ensuring the integrity of the molded parts.

Superior Performance

EZ-Kote mold release agents offer unparalleled performance in compression molding applications. Our formulations minimize the risk of sticking or tearing during demolding, resulting in higher productivity, reduced scrap rates, and lower production costs for manufacturers.

Tailored Solutions

Every compression molding application is unique, with specific material requirements and processing conditions. 

That’s why the team at EZ-Kote offers custom formulations tailored to meet our customers’ exacting requirements and specifications. Whether you’re working with rubber, urethane, composites, or other materials, we can develop a mold release solution optimized for your process.

Environmental Friendliness

Environmental sustainability is a top priority. EZ-Kote’s water-based mold release agents offer a greener alternative to traditional solvent-based formulations. 

They are non-toxic, non-flammable, and emit low amounts of volatile organic compounds (VOCs), ensuring a safer working environment for operators while reducing the ecological footprint of manufacturing operations.

Enhanced Surface Finish

In addition to facilitating easy release, EZ-Kote’s mold release agents contribute to improving surface finish quality. 

By reducing surface defects such as air traps and knit lines, our products help manufacturers achieve smooth molded parts, enhancing the overall quality of the final products.


EZ-Kote’s water-based mold release agents help manufacturers streamline their production, reducing overall costs by minimizing the need for secondary operations such as cleaning and rework. Our custom formulations are designed to maximize the longevity of mold surfaces, extending maintenance intervals and prolonging the lifespan of expensive tooling equipment.
