Used across many industries in the manufacture of products comprised of various materials, Thermex-Thermatron RF Hydraulic Presses are engineered to exacting standards for reliability and dependability. Below are three (3) of our fully customizable hydraulic models:

Hydraulic Seal and Cut RF Press

25 Ton Hydraulic Seal and Cut RF Press

Our heavy-duty hydraulic seal and cut RF press, the 25 Ton model, is ideal for tough jobs where maximum throughput is necessary at all times. As is true for our Four Ton RF Seal & Cut Press, this model has uniquely combined the sealing and die-cutting operations specifically for those materials that cannot be tear-sealed through conventional dielectric heat sealing methods. Our air/hydraulic and air operated Radio Frequency Platen Presses can be customized to your exacting specifications for both sealing and cutting.
