Up- and down-stream accessories

Process conditions can be simulated in the laboratory with different die geometries and post-extrusion equipment. A hot polymer melt can be shaped as it leaves the extruder with an appropriate die on a torque rheometer or compounder. Such dies might include rod dies, adjustable slit dies, blown film and catheter dies, or fiber and wire coating dies. 

The handling of hot, formable extruded material is a crucial part of the manufacturing process as it significantly influences the properties and surface finish of a material. We offer a wide range of dedicated post-extrusion equipment for such work. The equipment can transport extruded material downstream, prepare it for further tests or mimic full-scale processes. As such, it can be used for small-scale production which is especially helpful when alterations to the polymer formulation and processing parameters are necessary. 

A selection of our accessories for extruder sizes of 11mm, 16mm, 24mm, and for torque rheometers is listed below. Contact us for information about additional accessories.
