Plastics & Recycling

Enables effective removal of trapped gases during polymer extrusion, supporting precision and quality.

Ensures moisture-sensitive materials like PET and PA are processed without degradation.

Ensures precise shape and dimensional control in plastics production, with reliable vacuum calibrators for cooling processes.

Supports expanded polystyrene (EPS) bead transport and steam moulding processes for lightweight, durable products.

Facilitates efficient transport of raw materials and granules across production lines using side channel blowers.

Balances vacuum and pressure for consistent moulding and thermoforming results, improving product integrity.

Supports solid-state polymerization (SSP) and liquid-state polymerization (LSP) processes for high-performance materials.

Elmo Rietschle offers a wide range of vacuum pumps designed for plastics industry applications, including screw pumps for extrusion degassing and liquid ring pumps for wet environments.

Vacuum degassing removes trapped gases and impurities during extrusion, improving the quality and mechanical properties of the final polymer.

Screw pumps are dry-running and energy-efficient, ideal for moisture-sensitive materials, while liquid ring pumps handle wet or contaminated environments effectively.

Vacuum calibration ensures precise shaping and cooling of extruded materials, maintaining dimensional accuracy and product quality.

Vacuum systems support EPS bead transport, steam moulding, and pressure/vacuum balancing in thermoforming processes to produce consistent, lightweight products.

Side channel blowers are used for air transfer and pneumatic conveying of granules, compounds, and other lightweight materials in plastics production and recycling.
