Improve your extrusion process with a static mixer

Interfacial Surface Generator (ISG) Static Mixers. The Ross Interfacial Surface Generator (ISG) is one of the most widely used static mixer designs in injection molding and extrusion applications. The ISG (US Patent No. US3404869) consists of solid elements bored with four holes which provide the flow paths for the process fluid.

Static Mixing Technology For Extrusion and Injection

CRD mixers have proven their effectiveness in extrusion (2-4); however, their use is not limited to single screw extruders. The same mixing devices can be used in injection molding. Perhaps the most convenient method to enhance the mixing capability in injection molding is to design mixing elements into the non-return valve.

How Blenders Work : Plastics Technology

Blenders can combine materials by volume (volumetric) or by weight (gravimetric) and may operate either continuously (typical for extrusion) or by batch (typical for injection molding). The use of a blender saves the processor money in valuable additive materials by assuring a consistent metering cycle that does not need to be over-dosed ‘just in case’.
