Plastic Welding: Techniques & Processes for Thermoformed Parts
Welding techniques for welding plastics
How Plastic Welding Works
Plastic welding is one of the material and form-fit joining techniques. After welding, the two parts to be joined are inseparably connected. Plastic welding creates a connection that is not only of higher quality but also more stable than glued areas or components. Various plastic welding processes for thermoplastics are used for deep-drawn parts. The three most common processes for welding plastics are ultrasonic welding, vibration welding and high-frequency welding.
Benefits of Plastic Welding
Fast and Cost-effective
Plastic welding offers short process times and low energy consumption, helping you save both time and costs.
Versatile Welding Techniques
From ABS and PP to ASA and PVC, plastic welding accommodates various thermoplastics with different welding methods.
Eco-Friendliness in Plastic Welding
Unlike adhesive bonding, plastic welding does not require solvents, making it an environmentally friendly solution. Welded plastic components can be fully recycled, supporting a circular economy.

Plastic Welding Techniques
How it works
In ultrasonic welding, mechanical vibrations are generated by the welding machine, which create frictional heat in the plastic. As a result, the material softens and can be joined at the melted points.
Advantages
- Ultrasonic welding is a fast process in plastic welding
- Sealing time can be set precisely, which leads to a high reproducibility of the desired joining behavior
- The closed-loop concept also plays a role: The ultrasonically welded deep-drawn parts can be recycled into pure recyclate
