What are the typical applications for infrared welding of thermoplastics?

TWI Frequently asked questions

by Felicity Chipperfield

Infrared welding has been used for the joining of plastics pipes, since the early 1990s. Other potential applications include welding of uPVC window frames, biomedical products where high production rates of welded seals are often required in flexible materials, and in the fabrication of laminates or in the manufacture of parts from thermoplastic composite materials, where the process is able to achieve high energy densities over large areas.
