OVERVIEW:
Compounding

compounding.jpg

In compounding, various materials are mixed and melted—generally in an extruder of some type—then pelletized. This pelletized material is subsequently processed into a finished or semi-finished part by either molding or extrusion. Most compounding is done on twin-screw extruders of either co-rotating or counter-rotating design. Other types of equipment, such as ingle-screw extruders, kneaders and mixers, can also used to compound materials. From this zone you will be able to navigate to more specific information on single- and multiple-screw compounding.
