What is ultrasonic welding?
Ultrasonic welding is the joining of plastic parts with the aid of ultrasonic vibration. Due to a local fusion of the plastic components, the weld forms a permanent high quality invisible connection. This technique is fast, provides a high precision, it is applicable to complex shapes and does not require any additives.
Roughly speaking, joining of plastic can be done with or without adding material. The choice to weld without additions like an adhesive or sealant is often based on automation. Reasons to choose for the connection of plastics without adding material include:
- Short to very short cycle times
- High guaranteed reproducibility
- Easy automation
- No additives in manufacturing 'cradle to cradle' products
