CRYSTAL HF welder is created for the production of crystal clear PVC windows and cinema and projection screens with Invisible Seam technology. With the use of special tools the CRYSTAL HF welder creates a strong and very thin linear weld to join crystal clear PVC film.

Machine has a 6 m work table. A special back and front trough configuration and fabric layout during welding provides effective and an automatic weld/cut/press cycle to make the thin-line weld virtually invisible. The final pressing (if needed) is achieved with a separate, independent welding bar which can be used for omega profiles and standard linear welds as well.

Fully advanced programming functionality, including ATS™ auto-tuning and WCS™ systems is achieved thanks to an onboard PLC integrated with a 10" touch screen HMI. CRYSTAL machines have smooth HF power output 1-4 kW with high precision down stroke mechanism and a pressure control.

The vacuum section of the work table with special magnetic attachments allow for easy positioning of films/fabrics and welding of zippers with the use of optional tools. The CRYSTAL HF machine is a ready to use solution. There is no need for assembly and special installation.
