35kHz Ultrasonic Welding Equipment for Automotive Parts Assemble Technology

Description:

Ultrasonic plastic welding, through high-frequency vibration will be vertical energy to the welding surface, so that local high temperature, due to poor thermal conductivity of plastic, gathered in the welding area, resulting in the rapid melting of the two plastic, gathered in the welding area, resulting in the rapid melting of the two plastic contact surface, plus a certain pressure, so that it fused into one.

Ultrasonic welding is widely used in the automotive industry. The sonotrode is correctly dimensioned through the use of finite element analysis (FEA). Applications range from interior components (side door trim, center console) to engine compartment components (cylinder head cover, engine covers), to lighting, filters and acoustic foams. Welders can be operated immediately without heat-up time. Cycle times are short, and energy consumption is low.

Application :

Auto parts: bumpers, air filters, car audios, foot pads, door panels, clutch forks;

Electric products: humidifiers, chargers, storage battery, telephones, sockets, flash discs;

Medical products: leucocyte filters, accurate liquid medicine filters, blood plasma separating cups;

Packaging and clothing: valve bags, paper cups, dairy food packing cases, bag belts, zippers;

Stationery and toys: ink boxes, file folders, name card holders, albums;

Advantage:

1. Ultrasonic is the fastest, most repeatable and economical assembly method available to the industry today. 

2. With ultrasonic, most thermoplastics can be assembled without heat, mechanical fasteners, or hazardous consumables such as adhesives or solvents. 

3. Ultrasonic can join parts - small or large, simple or complex - with lower reject rates than any other method.

4. Using ultrasonic, labor - both as a skill factor and as a time factor - is significantly reduced. And since the equipment can readily be automated, any non-technical operator can be trained in minutes to produce high volume, high integrity assemblies.

Types of ultrasonic assembly:

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. 

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. 

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.
