35kHz Precision Ultrasonic Welding System for Assembly Plastic Parts


Ultrasonic welding is the clean, fast and reliable method of joining plastics, It is the use of ultrasonic frequency mechanical vibration energy in the work-piece surface to produce the plastic deformation and failure under the pressure surface , realize the welding method.

Ultrasonic welding process is most commonly used to join the thermoplastics, It is used in joining the materials which are not similar and it does not require any bolts, soldering material, nails or the adhesives that are needed to join the materials together.

Application :

• Thermoplastics

• Non-crystalline plastic

• Semi-crystalline plastic

• Non-woven fabric

• Thermoplastic fabrics

• Polymeric materials

• Coated paper

• Mixed fabrics

5) Horn shapes could be round, square or other shapes.

6) Welding time: 0.1 - 10s

Types of ultrasonic assembly:

1. Ultrasonic vibratory energy is used in several distinct assembly and finishing techniques such as: 

Welding : The process of generating melt at the mating surfaces of two thermoplastic parts. When ultrasonic vibrations stop, the molten material solidifies and a weld is achieved. The resultant joint strength approaches that of the parent material; with proper part and joint design, hermetic seals are possible. Ultrasonic welding allows fast, clean assembly without the use of consumables. 

2. Staking : The process of melting and reforming a thermoplastic stud to mechanically lock a dissimilar material in place. Short cycle times, tight assemblies, good appearance of final assembly, and elimination of consumables are possible with this technique. 

3. Spot Welding : An assembly technique for joining two thermoplastic components at localised points without the necessity for preformed holes or an energy director. Spot welding produces a strong structural weld and is particularly suitable for large parts, sheets of extruded or cast thermoplastic, and parts with complicated geometry and hard-to-reach joining surfaces.
