This Leistritz ZSE60MAXX-48D is a used plastic extruder — also commonly referred to as a compounding extruder — manufactured in 2012 and currently located in Germany. Plastic extruders of this type are used to melt, mix, and shape polymer materials into continuous profiles, pellets, or finished forms, and are central to industries such as plastics compounding, masterbatch production, and advanced materials processing. Leistritz is a well-established German manufacturer with a long-standing reputation in precision extrusion technology, producing machinery widely used across the plastics, pharmaceutical, and chemical industries.
This machine is a co-rotating twin-screw extruder configured for high-performance compounding of advanced polymer materials, with a particular focus on biodegradable polymers and bioplastics, though it is adaptable to a range of extrusion processes including masterbatch production and specialty compounding.
The screw geometry is defined by a diameter of 61.9 mm, a screw centre distance of 50.0 mm, and a screw length of 48D. The feed screw diameter ranges from 55.0 to 61.9 mm, and the kneading discs and kneading blocks measure 61.7 mm in diameter. Both the screw and barrel are manufactured from VSA2 material, with a barrel diameter of 62.3 H8. The screw length of 48D indicates a relatively long processing zone, which supports thorough mixing, degassing, and compounding of demanding formulations.
The drive system consists of a three-phase motor delivering 121 kW of drive power, with a maximum motor speed of 1,620 rpm and a gear ratio of i = 4.05, yielding a maximum screw speed of 400 rpm. Each screw is rated for a mechanical torque of 1,375 Nm, giving a combined torque of 2 × 1,375 Nm. Power is transmitted via a safety coupling with a shutdown torque of 220 bar, and the system supports a maximum melt pressure of 220 bar and a maximum melt temperature of 350 °C.
Thermal management is handled across 11 temperature-control zones with a total heating power of 100.80 kW, matched by 11 cooling zones. The cooling system uses Leistritz's ZIK intensive barrel cooling arrangement, with water cooling applied to the feed zone. The injection height is 1,050 mm. Machine weight is specified on the machine frame rather than listed separately in the documentation.
