Off-line Cold Straining with TGF + GP System

• System Overview:
  • The TGF + GP system is designed for off-line cold straining of rubber compounds.
  • It consists of a TGF cold feed extruder followed by a GP gear pump.
  • Ideal for processing pre-mixed rubber compounds that have been cooled and stored before straining.
• TGF (Cold Feed Extruder) Functionality:
  • The TGF extruder is responsible for preheating and homogenizing the cold rubber compound.
  • It uses frictional heat and controlled temperature zones to bring the compound to the ideal processing temperature.
  • Ensures uniform temperature distribution, improved material plasticity, and better flow consistency.
  • Helps to eliminate cold spots or inconsistencies in the stored rubber batches.
• GP (Gear Pump) Functionality:
  • Positioned downstream of the TGF, the GP gear pump performs precision straining and material metering.
  • It removes solid contaminants such as metal particles, fiber bundles, or agglomerates.
  • Also preforms the compound into continuous strips, making it ready for further processing or packaging.
  • Delivers consistent output pressure and volume, improving quality and downstream performance.
• Off-line Operation Characteristics:
  • Operates independently of the mixing line, allowing for greater scheduling flexibility.
  • Suitable for post-processing rubber stock, such as straining and preparing compounds for later use or shipment.
  • Ideal for central compound preparation facilities supplying multiple production lines.
• Optional Enhancements:
  • Can be equipped with an automatic screen changer to reduce downtime and ensure continuous operation during filter pack replacements.
  • Integration with cooling conveyors or strip winders is possible for handling and storage after straining.
• Key Benefits:
  • Improves compound cleanliness and quality before final processing or molding.
  • Reduces material waste and the risk of defective products due to unfiltered impurities.
  • Provides consistent strip dimensions, enhancing efficiency in downstream extrusion or molding equipment.
  • Increases plant flexibility by decoupling mixing from straining operations.
