－> cooling bath －> water wiper －>strand pelletizier
Main features of extruder
Closely intermeshing screw profile with screws that are self-wiping at narrow clearance for easy product and color changing.
Special mixing and shearing elements is with varying effects for high process flexibility.
Modular building-block system for barrel;
Each barrel is with one temperature zone for optimal processing.
High reliable safety clutch and interlocking system for optimal protection against overload
High torque gear box ensure high output and long life time.
Variable screw speed from 100 to 800 rpm allows wide range of process technologies.
Large free volume due to outer/inner screw diameter ratio Do/Di ~ 1.75 for optimum processing.
Water manifold completely made out of stainless steel.
