Maximum flexibility, absolute precision: the ideal choice for complex PVC joints

The SLTV from Graf Synergy is a single-head welding machine designed to offer maximum versatility for the most technical and complex operations. Thanks to its variable angle head, it allows for corner welds ranging from 35° to 180°, including configurations such as ‘T’, cross, or ‘H’ (notch welding). The fully automated cycle ensures consistency, repeatability, and a reduction in errors, even with pointed cut profiles and V-grooved workpieces. It is ideal for manufacturers looking to expand their range of fixtures while providing a highly customised service.
