High-quality seals

Mega is a perfect machine for production of laminated PU foam embossing, car/truck door panels and tops, automotive and airline carpeting and seat covers, car trunk floors and covers, as well as medical, laboratory, rehabilitation equipment, safety vests, reflective signs, etc. Optional heated electrode platen with temperature presets gives high accuracy for consistent welding.

The machine is equipped with special quick change electrode holder. Custom-built tooling and electrodes are available upon request. We have our own in-house tooling department which will design and make any electrode and die required for any demanding production needs.

With the use of touch screen HMI and programmable PLC, the operator can easily input multiple weld/seam recipes. MEGA series have HF power outputs from 15kW to 30kW for heavy production loads and special projects using reinforced heavy-duty materials. All these options make this machine a perfect tool for high-end production where precision, durability and strength is the key.

Why is our technology unique?

WCS™ Weld Check System
Verifying and signaling the HF/RF weld preset parameters / end cycle process. Collects all data pertaining to each weld cycle for remote diagnosis of any issues or problems with machine setup or power output.
QuickGrip™ System
System for quick and easy replacement of electrodes. The electrodes are attached with pneumatic clamps activated from the control panel.
AntiFlash™ System
Ultra-fast Solid-State ARC sensor & full output overload protection.
ZTG iCOM™ System
Built-in VPN client and VNC server making up the internet interface allowing remote control of machine parameters, weld cycle and diagnostics or software upgrade.
Safety guards
Special guards with safety limit switches designed for protection against electromagnetic radiation (compliance with EN and EMC standards).


ZEMAT TG High Frequency welding machines are designed and built to very strict European Environmental and Safety regulations and have custom design solutions for weld and safety control.
