Core Plastic Welding Processes

These are the core processes of our plastic-welding-based services.

  • Ultrasonic welding and related processes (swaging, cutting, sewing, and more)
  • Laser welding and surface treatment
  • Infrared welding (through-transmission and standard)
  • Friction welding (spin, linear, etc.)
  • Vibration welding
  • Thermal welding (staking, hot plate, film sealing, etc.)
  • Extrusion welding
  • Hot gas welding
  • Implant and radio frequency induction welding
  • Resistive implant welding
  • Adhesive bonding

Plastics Testing & Process Support

No process is complete without thorough testing and analysis. Here is a selection of techniques we employ to be sure we’re developing the most effective plastics solution.

  • Dynamic mechanical analysis (DMA)
  • Differential scanning calorimetry (DSC)
  • Microtome testing
  • CT scanning
  • CT metrology for dimensional analysis
  • Material selection and weldability testing
  • Joint and tooling design
  • Fourier transform infrared spectroscopy
  • Microscopic analysis

Proven Solutions for Plastics Joining

EWI has more than a 25-year history of innovation with plastics welding and joining for across-the-board manufacturing sectors. We’ve been an instrumental part of some proud breakthroughs over the years:

  • Developed a method to powerfully bond a polymer film to a thin metal sheet without the use of adhesives
  • Published peer-reviewed research on joint design’s effect on ultrasonic welding of polybutylene terephthalate (PBT), which proved that a less-expensive, longer-lasting energy director could be used with servo motion control during ultrasonic welding * Patented ultrasonic technology, UltraThinSeal™, for high-speed package film sealing that can be easily integrated into most standard thermal sealing bagmakers
