Twin Screw Extruders & systems

Well developed product portfolio

Leistritz has long been established on the global market in the manufacturing of co-rotating twin screw extruders. After all, we have been building and optimizing extruders for more than 80 years - first for the plastics industry then also for the pharmaceutical and food industries. This is made possible not only by constant innovations and a ready ear for the users’ needs, but also by a dedicated team who bring many years of experience in this field to the table and stand behind the product with passion.

The Leistritz extruder series

The twin screw extruders from Leistritz convince with their compact and well thought-out construction, effective cooling and heating technology, and high quality and energy efficient drives. Alongside a modular barrel system, Leistritz offers a comprehensive system of various screw elements which offer great options for variation. The optimal layout of the screw geometry for each processing task is the art of our Leistritz process engineers.

ZSE MAXX series

The ideal combination of very high specific torque (up to 15 Nm/cm³) and a large volume (OD/ID = 1.66) in one extruder - this is the feature which makes the ZSE MAXX twin screw extruder stand out. An extremely large range of processes benefits from the maximal adaptability of the ZSE MAXX since it has high process engineering relevance. As a result processors no longer have to choose between high volume or high torque machines. They can get everything in one machine.
