  • Ultrasonic device for a polymer extruder machine
    Patent number: 11584043
    Abstract: An ultrasonic device comprising a chamber (10) provided with an inlet bore (11), which receives a melted pressurized polymer, an outlet bore (12) and a sonotrode housing bore (13) through which a distal portion (21) of an ultrasonic head (20) is inserted into the chamber, wherein the distal portion is separated from the rest of the ultrasonic head by a first nodal plane (PN1) wherein there is a first surface (S1) in contact with a complementary surface of a ring seal (30) that closes the chamber, and wherein the ultrasonic head includes a second nodal plane (PN2) away from and parallel to the first nodal plane (PN1) coinciding with or adjacent to a second surface (S2) wherein an anchoring device (40) presses the ultrasonic head against the ring seal ensuring a tight closure.
