Specialized in solving customer challenges, American Kuhne is the preferred provider of engineered solutions for plastic, rubber & silicone extrusion. American Kuhne solutions comprise standard and custom single screw extruders, feed screws, extrusion systems & specialized turnkey systems for medical tubing, laboratory, narrow web, wire, cable ...
A plastic extrusion screw must convey, melt, and force plastic resin through a forming die to create a product. This process is accomplished by moving the raw material through three separate sections of the screw, each designed to fulfill a specific function.
In twin screw extrusion processing, the raw materials may be solids (powders, granulates, flours), liquids, slurries, and possibly gases. Extruded products are plastics compounds, chemically modified polymers, textured food and feed products, cellulose pulps, etc.

Plastics extrusion is a high-volume manufacturing process in which raw plastic is melted and formed into a continuous profile. Extrusion produces items such as pipe/tubing, weatherstripping, fencing, deck railings, window frames, plastic films and sheeting, thermoplastic coatings, and wire insulation.
extruder/injection machine cylinders and screws. It is important to measure the shear rate dependence and temperature characteristics of viscosity, which differ ... of rubber in extrusion processing is relatively high. This is related to the plug flow behaviour of rubber flowing in a narrow tube (q.v.).
Longitudinal section of a screw extruder of thermoplastic polymers. Plastic pellets are fed from a hopper into the barrel of the extruder, where the pellets are gradually melted by mechanical energy generated by a turning screw and by …
Feeding of the extruder is independent of screw design. For successful operation of any single screw extruder a consistent feed stream must be supplied. The feed stream must be of uniform composition and uniform weight.
cooling in extrusion/injection moulding machines The melting and flow of rubber created by the barrel and screw in an extruder are accomplished by raising the rubber temperature with the heat source mounted around the outside of the cylinder as in Figure 2 [2-5], by friction between the rubber and screw…
The screw depth of a HFE is relatively larger and you get a consistent output due to its short screw design. L/D ratio is mostly in the range of 4:1 to 6:1 which keeps your rubber compound dwell time and its temperature increase to a minimum.
The cold feed extruders have been developed for processing cold rubber compound.Since these machines,in addition to extruding profiles also plasticize rubber,they differ from hot feed extruders.they have longer screws,heavyier gear boxes and higher drive power.
Brabender® twin screw extruders have been designed for use in laboratory simulation and compounding. They are powerful and highly flexible. They are powerful and highly flexible. They enable seamless adjustment of processing machines for laboratory ...
Cold feed extrusion is when the plastic/rubber material is fed into the machine at room temperature. Hot Feed Hot feed extrusion is when the plastic/rubber material is fed into the machine after being heated.
