The VACUUM BELL is used for testing the tightness of overlap welding seams and application seams. The needed vacuum is ideally generated by Leister’s VACUUM PUMP.
The WELDPLAST S4 is the first extrusion welder of its kind with brushless, maintenance-free motor for generating preheated air. Output of up to 4 kg / 8.8 lbs. of extrudate per hour is made possible thanks to the S4's powerful drive system.
