Cylinder Type Hand Welder Ultrasonic Assembly Spot Welding System ABS PP

Cylinder Type Hand Welder Ultrasonic Assembly Spot Welding System 35kHz 1000W ABS PP

Dscription:

The ultrasonic waves vibrate 10's of thousands of times per-second. This oscillation is transferred to a contact surface that is directly in contact with the plastic parts. Since the boundary of the welding area has a large acoustic impedance, it produces high temperatures. Plastic is a pretty poor conductor of heat and can't dissipate the heat before it changes the state of the plastic from solid to liquid. With a bit of pressure applied, this makes the two parts blend together as if they are a single piece of plastic. Once the ultrasonic signal is stopped, the parts become solid again. This is the magic that creates a weld between the two parts that is clean and very strong. The weld will have a strength that is close to that of the raw materials being formed together in an injection molding process.

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.

Application:

Ultrasonic plastic welding is also utilized in the medical industry, primarily because it doesn’t introduce contaminants. Items such as anesthesia filters, blood filters, IV catheters, dialysis tubes and face masks can be made using ultrasonic plastic welding. Another important application in the medical field is the construction of such textile wear as hospital gowns, surgery garments, and transdermal patches, just to name a few. These items can be sewn and sealed using ultrasonic plastic welding to avoid and reduce the risk of infection.

Ultrasonic plastic welding is frequently used in the packaging industry. Everyday items, ranging from butane lighters to food containers, are created or packaged with ultrasonic plastic welding. Ultrasonic plastic welding is also found in the packaging of dangerous explosives, such as fireworks or dangerous chemicals. These items can’t be subjected to high temperatures, yet must be contained in an airtight container that can withstand stress and high pressure.

The food industry relies on ultrasonic plastic welding because it’s fast and sanitary while producing airtight seals. Milk and juice containers are prime examples of products sealed with an ultrasonic plastic welding machine. To complete the task, paper cartons are coated with sheer layers of plastic that are then welded together.
