The Role of Vacuum in Plastics & Composites

Controlled conditions are important in plastics and composites manufacturing, and vacuum technology helps create the clean, stable conditions these processes rely on. By removing trapped air, moisture, vapors, and allowing materials to be processed at lower temperatures, vacuum helps maintain material quality and prevents issues that can affect the final part. This cleaner environment supports smoother processing and more consistent results across different manufacturing processes.

Stokes vacuum pumps are built to handle these demands, delivering steady performance and cleaner operation across plastics production and composite work. Our pumps help improve efficiency, reduce maintenance needs, and support reliable output, keeping your manufacturing processes running smoothly and confidently.

Common Plastics & Composites Applications in Today’s Industries

Vacuum Thermoforming

Vacuum thermoforming shapes heated plastic sheets by removing air behind the softened material, drawing it tightly over a mold. This creates uniform contact across the surface, resulting in accurate, repeatable parts and smooth forming performance supported by consistent vacuum levels.

Plastic Recycling

Vacuum plays an important role in plastic recycling by extracting gases and impurities, supporting cleaner processing and higher quality material output. This creates more consistent material that can be reused more effectively.

Vacuum Degassing

Vacuum degassing removes dissolved gases, vapors, and moisture from liquids or paste by exposing them to lower pressure. Reducing the pressure makes these gases less soluble, allowing them to escape quickly and cleanly from the material. This controlled process helps prevent bubbles, reactions, and impurities that can affect product quality.
