Foam under control

Foam Extrusion. A thorough control notion links the individual the different parts of modern foam extrusion systems. Improvements in throughput together with shutdown and startup of the complete system happen largely automatically, and found in a user-friendly manner reproducibly.

Typical raw materials formulations for foam extrusion contain up to 8 components that must be processed under described conditions. Gear manufacturers face the task of developing technology and control ideas that ensure reproducible creation of semi-finished foam products.

The twin-screw extruder is fed with the polymeric recycleables through a gravimetric unit(loss-in-weight feeder) and this determ
