Compounding and extrusion accessories

The handling of hot, formable materials is a crucial part of extrusion in manufacturing, significantly influencing the properties and surface finishes of these materials. Thermo Fisher Scientific offers a wide range of dedicated post-extrusion equipment for such work. These accessories can transport extruded material downstream, prepare it for further tests, or mimic full-scale processes. As such, post-extrusion equipment can be highly practical for small-scale production, where alterations to the polymer formulation and processing parameters are necessary.

A selection of our compounding and extrusion accessories is listed below. Contact us for more information about additional accessories.

Accessories for compounding and extrusion equipment

	Extrusion process	Accessory
Upstream (pre-extrusion) Dry raw materials have a variety of appearances and flow behaviors. It is crucial for these powders, granules, and pellets to be precisely and reproducibly metered into the extruder. These critical upstream accessories influence overall process performance.	Pre-extruder	Dry material feeders Choose from a wide range of volumetric and gravimetric solid feeders with feed screws that adapt to material properties.
	Pre-extruder	Liquid feeder devices Select feeders based on the temperature dependence and viscosity of your materials, tailored to your specific process needs.
Extrusion Special die designs can produce unique, desired forms in the hot polymer melt as it leaves the extruder. This allows you to create a variety of test specimens for further analysis.	On-extruder	Sheet die designs Produce sheets of different widths and thicknesses (fixed gap or flexible gap design)
	On-extruder	Rod-die design Single and multi-strand versions available with different diameters. For pelletization and die swell studies.
Downstream (post-extrusion) Extruded materials must be handled with care while they are still hot and formable. Specific take-off devices make sure the material is treated right for further processing.	Post-extruder	Chill roll Precisely control cooling rates for continuous cooling, solidifying, and flaking of viscous materials.
	Post-extruder	Conveyor belts and strand pelletizers Effectively cool and cut the extruded strands into pellets of different sizes for direct use or further processing (e.g., milling).
	Post-extruder Sampling	Direct shaping of polymer melts Use the Thermo Scientific HAAKE Minijet Pro Piston Injection Molding System to prepare test specimen for mechanical analysis.
