RAM extrusion is a continuous process used for the production of semi-finished PTFE rods and tubes.
A pre-sintered or free-flow PTFE resin is inserted into a mold where it is pressed and sintered, simultaneously, in a vertical extruder.
The sintering process generally takes place by heating the mold with bent heaters at a temperature above the melting point of the polymer.
Subsequently, the semi-finished product is cooled to a rate that will bring the desired crystallinity to the polymer.
• Extruded tubes: range from a size of O.D. 8 mm up to 150 mm
• Extruded rods: range from O.D. 4 mm up to 160 mm
