March 27, 2025
They are available with a more durable coating and modified geometry for efficiency.

High-performance screws Engel’s three-zone mixing screws and barrier screws produce homogeneous melt, both materially and thermally, ensuring high-quality end products. The three-zone mixing screws can process a wide range of plastics at high throughputs. Available in various lengths and geometries, the company’s barrier screws are durable and deliver short cycle times and long service life.  

What’s new? New screws that have been modified in the last year. For example, Engel now offers screws with a more durable coating. Additionally, slight modifications have been made to screw geometry to improve efficiency, which is particularly important for high-throughput applications. 

Benefits Efficient and consistent plastic processing.
