Ultrasonic Spot Welding Equipment for High Power Electrical Appliances

 

Description:

 

Ultrasonic plastic welding is suitable for virtually all thermoplastics. When planning welds between semi-crystalline plastic pieces of work, it is important to remember that the weld behaviour of these plastics differs considerably from that of amorphous plastics.

Ultrasonic plastic welding can be used to a limited extent for joining together two different thermoplastics (amorphous plastics). Ultrasonic welding is not suitable for use with thermo setting plastics. Today ultrasonic welding is used in every industry that processes plastics. Most common uses are in the Automotive, Medical, Textile, Food, Plastics, and Packaging industries.



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.



Application:


Appliance

In this high-volume market, hermeticity, strength and also cosmetic appearance are important. Applications include: steam iron, pump housing, vacuum cleaner wand, and dishwasher spray arm.

Automotive

Hermetic seals in applications such as lenses, filters and valves. Other applications include: glove box door, instrument cluster, air diverter and mass airflow sensor.

Business

"Clean" assemblies with reduced particulate matter are produced on information storage discs. Other applications include the assembly for ribbon cartridges, and audio and video cassettes.

Consumer

Precision welding, staking and forming operations are used in the manufacture of the Swatch®.

Electrical

Multiple staking and inserting applications are often automated for high-volume production requirements with consistent reliability. Applications include: terminal blocks, connectors, switches (e.g. toggle, dip, rotary quick and diaphragm), and bobbin assemblies.

Medical

Non-contamination and the ability to be operated in a clean room are as important as the strength of the weld. Reliable, repeatable assemblies for critical life-support devices are produced with new capabilities in process control. Applications include: arterial filter, cardiometry reservoir, blood/gas filter, face mask and IV spike/filter.

Packaging

From aseptic packages to toothpaste tubes, the ability of ultrasonic assembly to seal through product contamination in the joint area is a major advantage. In addition to good cosmetic appearance, ultrasonic assembly provides tamper-evident seals for blister packs. Applications include: condiment dispenser, blister package, juice pouch, juice carton and plastic coated paper cups.

Toys

In this highly competitive industry, the elimination of adhesives, screws and solvents, or other consumables is a bonus added to strong, safe, flash-free assemblies.
