Plastic Welding


Technical Expertise

These are the core processes of our plastic welding and related services:

  • Ultrasonic welding and related processes (swaging, cutting, sewing, and more)
  • Laser welding and surface treatment
  • Infrared welding (through-transmission and standard)
  • Spin welding
  • 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

Testing & Analysis

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 (FTIR) spectroscopy
  • Microscopic analysis
  • Air decay leak testing
  • Diffusion analysis
  • Mechanical testing (tensile, shear, peel, push, impact, etc.)
