RAM EXTRUDED PRODUCTS

Ram extrusion is the process where, a ram or plunger is used which forces the material through a die at the end, instead of an extrusion screw. As the screw extruder has high viscoelasticity for PTFE and other polymers after heating, it is not recommended to use it. Hence, it is required to use a ram extruder. Here the PTFE or PEEK material is fed into a chamber, where it is pushed by a ram and continuously heated through an extrusion tube of the die. The preforming, sintering, and cooling processes then occur consecutively inside the die. The die provides mostly round-shaped objects such as tubes, rods, and profiles, etc.
