SIGNA 4

Front load pneumatic drive work tray high frequency welder

SIGNA 4 single station front load shuttle high frequency welder with 4kW stable controlled HF power output is made for various industrial high frequency welding and heat sealing applications requiring precision flat surface for product positioning and complex shape welds.

The machine is suitable for welding materials such as: PVC, PU, PET, A-PET, PLA.

Applications

Machine modifications

Universal welding machine

SIGNA 4 is a perfect machine for production of blister & clamshell packages, medical containers like blood or ostomy bags with switchable welds for tubes and outer edge, laboratory, rehabilitation equipment, automotive parts, cosmetics, etc. Heated electrode plate with temperature presets gives high accuracy for consistent welding of hard PVC/PET foils or PU foams.

The high frequency welder can be easily converted to a standard Heat Sealer for applications where high frequency welding is not necessary or impossible (e.g. PP or PE materials). 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 save multiple (1000) weld/seam recipes.

All available options, settings and safety features 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).
