The Reifenhäuser Trudes 115 is a used plastic extruder — sometimes referred to as a screw extruder — manufactured in 2013 and currently located in Germany. Plastic extruders are industrial machines that melt and continuously force thermoplastic material through a shaped die, making them fundamental to the production of pipes, profiles, films, and similar products. Reifenhäuser is a well-established German manufacturer with a long history of supplying extrusion machinery and complete extrusion lines to the plastics processing industry worldwide.
This particular machine is a counter-rotating twin-screw extruder in a compact configuration, designed specifically for pipe extrusion. It is built with highly tempered steel and a bimetal design and comes supplied with a matched pair of screws. The barrel diameter is 115 mm with a 30:1 length-to-diameter ratio, and the barrel incorporates both atmospheric and vacuum degassing openings. A vacuum unit is included, comprising two vacuum units and a vacuum suction unit, supporting effective degassing during production. The screw temperature control system is complete and features cassette installation.
The gearbox integrates a back pressure bearing rated to 350 bar, and the lubrication system uses recirculating oil with continuous monitoring of both oil pressure and oil temperature. Heating and air cooling are divided into five zones, and the total installed heating output is 56,400 W. A mains supply assembly with a main switch and load disconnector covers heating, drives, and auxiliary voltages.
The drive system consists of a single AC motor operating under vector control, paired with a fully digital drive controller for AC motors. Motor temperature is monitored continuously, with both a pre-warning stage and an automatic shutdown function. The machine is configured for a stationary extrusion height of 1,000 mm.
The control cabinet contains all necessary control and regulation equipment. Temperature control is handled by a microprocessor-controlled multi-channel controller suitable for two- and three-point zones, with adaptive, self-optimising control behaviour. The system logs fault messages with a collective alarm and stores them for review, and supports recipe management for up to 20 stored recipes.
Additional equipment included with the machine comprises two electrical melt pressure transducers (½" UNF diaphragm type) and two ground temperature sensors fitted with sword probes. The machine was last reported as still connected to power.
