Specialists in joining plastics

The ability to weld a plastic component is determined by:
- Physical and mechanical properties of materials
- Welding parameters: time, temperature and pressure
- Design of the weld and the component
- Applied welding technique

An indication of the weldability of some thermoplastic materials associated with welding can be found in table 1
