Product Specification

Ultrasonic Plastic Welding Machines

Principle Of Welding
The principle of ultrasonic welding is using the ultrasonic high frequency oscillation to produce oscillation energy at approx. 20,000 times of oscillation per second to weld the work pieces, while the molecules will be melted to make a firm welding. if the welding surface has been oxide coated, during the ultrasonic oscillation welding, the surface oxide coating will be stripped so that the pure metal surfaces can be welded completely.

Features

Short welding time, welding can be finished within a second.
Use 220V power supply, short welding time, therefore, very few power consumption.
Because of momentary high temperature welding, the temperature of the work piece will not exceed its temper temperature, thus it will not affect the quality and hardness of the product, and its welding strength is higher than resistance welding or normal electrode welding, and will not damage the welded surfaces (no damage of metal properties) and the welding joint is smooth and clean.
After welding, the work piece has good electric conductivity, and its resistance coefficient is very low, close to zero.
If there is any contamination or oxide coating on the metal surface, it can be welded perfectly.
No need of solder or welding flux, therefore, it can be welded economically and conveniently.
The welding horn, and jigs are made of steels, durable and long service life. Four kinds of welding horns are available for your selection.
The machine is robust and steady, easy for adjustment, high output, and can be integrated with automation machinery production lines.
No sparks during welding, safety for the operators. No smoke, therefore no air-pollution problem.

Ultrasonic and More
Ultrasonic energy is the creation and channeling of high-frequency sound waves for industrial purposes.

With plastics assembly, the energy is channeled through an acoustic tool called a ‘horn.’ The vibrations generate heat and cause subsequent melt where parts join. A strong molecular bond results. This assembly technique is fast, efficient, non-contaminating and requires no consumables, such as glue, making it ideal for industries seeking energy efficiency and productivity. The same principle pertains to sealing textiles and films.

For ultrasonic metal welding, an ultrasonic welder forms a weld by pressing the parts to be joined together and scrubbing them against one another to break up and disperse the surface oxides and contaminates. The resultant clean base metal surfaces are held tightly together. A metallurgical bond is created without reaching the melt temperature of the metals being joined.

Ultrasonic plastic compatibility chart
The term plastic can be used for thermoplastic or thermoset materials. Most thermoset material can not be ultrasonically bonded as they burn when heated. Thermoplastics are normal categorised as amorphous or crystalline.
Amorphous material exhibits a random, spaghetti like structure. They are good at transmitting the ultrasonic energy to the part that needs to be bonded. Amorphous material include: ABS, Polycarbonate and Acrylic.

Crystalline materials have an ordered pattern, and have a well defined melting temperature. Crystalline materials include: Acetal, Nylon, Polyester, Polyethylene and polypropylene.
The following grid can be used to assist with plastics suitable for ultrasonic welding.
E=Excellent, G=Good, F=Fair, P=Poor, NO=Not suitable for ultrasonic welding.
