Gearboxes of the highest quality are used to achieve the high speeds and torques required by compounding applications, reaction processes, degassing processes.
The cutting edge twin-screw model ZE-UTX/UT series is available in the ZE-A version and the ZE-R version, each with its own unique outer/inner screw diameter ratios (D/d ratios). With the ZE-A version (D/d=1.46), optimal torque can be obtained with respect to the selected volume, to provide high output at high screw torques. It is suitable for high performance compounding, alloying, filling, reinforcing, masterbatch production, and the processing of powders and fine particle polymers.
The ZE-R version (D/d=1.74) is designed for an even larger free volume than the ZE-A, obtaining a long resident time, making it suitable for high torque extrusions. It is characterized by optimal melt conditions, low gas volatility, and low shear input. It is suitable for processing of extremely highly filled materials, TPE compounding, reaction processes, concentrating, and degassing.
Using gearboxes of the highest quality to achieve high speeds and high torques, the ZE-UTX series also has an innovative fabrication method (special heat treatment) applied to directly harden the bore surface, bringing the cooling jacket and processing section closer to each other, which results in superior cooling effects.
The barrel has a modular design. Depending on the application, modular barrel blocks are combined to optimize barrel configuration. With C-clamp connectors, modules can be exchanged, and thus changes to barrel configuration can be carried out quickly. At the same time, the screw configuration can also be optimized due to the wide range of elements that are available for different purposes.
Moreover, by combining the extruder with a melt pump, compounding and forming can be carried out in a single process.
