RF Welding

RF welding is the process of fusing materials with high-frequency radio energy. It entails:

  • “Exciting” the poles of the polymer molecules, causing them to alternate and change field
  • Converting “field energy” to heat, creating a weld at the contact point of the two materials
  • Cooling the material to specifications

Pittsburgh Plastics Manufacturing can RF weld PU films, PU coated fabrics, PVC, PET, EVA and some forms of ABS.
