Radio Frequency Welding RFlex
The RFlex is Miller Weldmaster's most versatile stationary radio frequency (RF) welder. It uses high frequency electromagnetic energy to create strong, waterproof, airtight seams on PVC, PU, and TPU materials, producing welds that are nearly invisible and consistently repeatable.
Built for production environments where precision matters, the RFlex handles everything from tarpaulins and tents to truck tarps, high speed doors, billboards, inflatables, and pool covers.
Overview
Radio frequency welding machine for PVC, PU, and TPU
Radio frequency welding works differently from hot air or hot wedge methods. Instead of applying heat externally, RF energy heats the material from the inside out using controlled electromagnetic waves. The result is a stronger bond that's uniform across the entire weld area, with no charring or surface damage.
The RFlex is purpose built for flexible PVC (polyvinyl chloride), PU (polyurethane), TPU, and reinforced technical textiles. It can weld thick or thin material, reinforced or film, plain or patterned. The machine runs in manual, semi-automatic, or fully automatic mode, with 100 stored weld recipes so operators can switch between products without reconfiguring settings each time.
With autotuning that maintains steady RF power output, a QuickGRIP electrode release system for fast die changes, and a SafeDOWN anti-crush safety mechanism, the RFlex is designed to keep production moving while protecting both operators and materials.
