Description: Twin shaft extruder gearboxes for plastic extrusion are made as per Thyssen Henschel (Germany) design for TPM-3-65-28 Model. This has 55 mm centre distance and ratio of 28:1. The key attributes are compact design with high ratings owing to the use of high-strength, case-hardened steels, smooth running with low noise due to ground single helical gearing, vibration-damping housing of grey or nodular cast iron, helical gear unit not subjected to any screw back pressure forces, and maximum operating reliability.
