Can different types of plastics be welded together?

Ultrasonic welding thermoplastics can be highly successful when welding two materials of the same plastic material. However, in some cases, ultrasonic welding can also be viable for welding two different materials together. These dissimilar plastics must have compatible molecular structures and melting temperatures, determined through testing to ensure their weldability. Ultrasonic frequencies and clamp pressures must also be determined for each application. When in doubt, contact us to confirm compatibility of your different plastic materials.
