Ultrasonic welding plastic

Learn about ultrasonic welding , including the process and principles as well as the plastic welder equipment available through Dukane Intelligent Assemble Solutions. It is commonly used for plastics , and especially for joining dissimilar materials. In ultrasonic welding , there are no connective . With ultrasonic welding of plastics , plastic molecules are activated to create new cross-links among molecules. This creates a high-strength joint.

Process Description of Plastic welding technology: The ultrasonic welding technology for plastics is assigned to the melting-welding process.

Sometimes poor ultrasonic welds can be traced back to the injection molding process. Injection mold wear can lead to a rounded energy director in the part ( upper right), which produces a weak weld (lower right). A well-maintained mold produces a sharply pointed energy director (upper left), which produces a stronger . Understand and address the likely origins of welding problems to keep production on track. Branson ultrasonic plastic welders join rigid thermoplastic, fabrics and films with top precision. The plastic molecules mix together and form bonds.

Upon cooling, the plastic surfaces are welded together. Welding times can vary, but the welds can form in as little as 0.

The factors that vary in ultrasonic welding are the frequency of the sound waves (usually 2 or kHz), the pressure applied to hold the . An understanding of ultrasonic welders helps designers apply this assembly method efficiently. Ultrasonic Plastic Joining. There are many benefits of this technology. It allows for plastic parts to be assembled without consumables. This not only eliminates the cost of the consumable (such as screws or rivets), but in the case of adhesives and . It is an excellent technique for assembly of mass produce high quality products in plastic materials.

Sonimat solutions for bonding plastic with hot plate, infrare and spin welding machines. Sonics manufactures a comprehensive range of plastics welding equipment, tooling and components, from hand-held units to bench model presses to ultrasonic kits for OEM installation. Secon ultrasonic metal welding creates the weld via a frictional action of the surfaces that creates a solid-state bond without any melting of the material. The advantage of using this technique with plastics is that within seconds a high strength, gas and water tight bond is . It is accomplished by converting high- frequency electrical . DuPont engineering plastics.

Welding occurs as the result of heat generated at the interface between the parts. Frictional heat is produced so that thermoplastic parts melt and an insoluble connection between parts is forged in a very short . Bright Plastics ,Forward Technology . In recent years, the application of ultrasonic welding to plastics has become common. In this paper a method for ultrasonic welding of plastic pipes using torsional vibrations is reported.

In this method torsional vibrations are applied to the welding pipe from the circumferential direction with horns placed near the welding .
