Sonics Launches New X-Press Integrated Welder for 20 kHz Ultrasonic Plastics


(October 10, 2006 - Newtown, CT ) Sonics & Materials, Inc. announces the full production launch of its brand new X-Press 20 kHz integrated welder - an all-in-one super-rigid ultrasonic welding press with a built-in microprocessor. Available now, the press features a single-piece rigid cast aluminum machine base and column hub along with easy-access front panel pneumatic and microprocessor controls. The X-Press is available in 1200 watts (Model XP-1200) and 2200 watts (Model XP-2200) and welds in digital time and/or constant energy modes.

Engineered to provide maximum rigidity and user-friendly convenience in a single space-saving unit, the X-Press combines digital amplitude control, ultrasonic horn/stack frequency display, and timers (for weld, hold, delay and afterburst), with a heavy-duty 3.75” steel column diameter (0.50” wall thickness), direct in-line air cylinder, and a single rail linear slide.

Other standard features include ultrasonic power load meter, upper and lower weld limit settings, and back-lit LCD display. All models include soft-start overload protection circuitry, load regulation circuitry and digital wattage display. CNC precision-machined components, quick-release column clamps and head-adjust hand wheel with counterbalance head spring are also standard. To further simplify radial horn alignment a high-efficiency snap-in converter rotates 360 degrees. A threaded positive stop provides for fine adjustment and limits the downward travel of the horn.
