20 / 28 / 35Khz Titanium Ultrasonic Welding Horn For Spot Welder

20/28/35Khz Titanium Ultrasonic Welding Horn For Ultrasonic Spot Welding Machine

Titanium Ultrasonic welding horn for ultrasonic spot welding machine

Description

Ultrasonic welding of plastic materials creates a molecular bond within the weld seam. Longitudinal vibrations in frequencies of 20 kHz, 30 kHz, and 35 kHz with tool amplitudes between 5 µm and 50 µm are introduced into the plastic materials under the action of force. Ultrasonic vibrations are focused by means of special design of the components or tools.

Ultrasonic metal welding uses high frequency vibration waves to transfer to the metal surface to be welded. Under pressure, the two metal surfaces rub against each other to form the fusion between the molecular layers.

Interior

Ultrasonics is not only suitable for joining plastic materials with each other, but also for joining plastics and other materials, such as metal, or wood. Even chromium components are suitable for ultrasonic staking. By means of sonotrode grouping, it is also possible to realize particularly demanding joining tasks, such as welding of large instrument clusters. Brilliant surface finish and precise gap control is achieved.

Ultrasonic welding: ultrasonic vibration with ultrasonic welding mould, the ultrasonic welding energy conduction to the plastic surface, resulting in local temperature, so that the plastic surface melting. Under the pressure of the ultrasonic hand, so to weld plastic, beautiful, strong effect.

Ultrasonic implants: the nut screws or other metal into plastic work piece. Ultrasonic energy through the ultrasound machine will be transmitted to the metal. The high-speed vibration and heat, the pressure in the ultrasound machine to make metal objects embedded directly into the plastic inside.

Ultrasonic riveting: the nature of metal and plastic or two different plastic bonding together, can make use of ultrasonic riveting machine, so that the weldment hard brittle, beautiful, strong.
 

Ultrasonic welding: the use of ultrasound machine small welding head, the two pieces of plastic products into multi-point welding, or welding the first row of teeth on a direct pressure on the two plastic work piece, so as to achieve the effect of ultrasonic welding.

Requirements:

Components of Ultrasonic Welding (Horn, Booster and Transducer)

They can amplify the amplitude at a particular ratio step by step. For example, the transducer amplitude is 6mm, the booster can amplify it triply to 18mm, and then the horn can make it to 36mm. However, the work life of horn would be shortened with the amplification of amplitude. The required amplitude differs with the welding material.

There are three common horn material:

1. Titanium

high price, excellent performance good toughness and low loss, difficult to be processed;

Its amplitude can reach to 60mm.

2. Aluminum

low price, fast loss, easy to be processed;

Its highest amplitude less than 300mm.

3. Steel

too hard to be made as horn;

its highest amplitude less than 25mm;

It is suitable for cutting but the blowpipe need to be added in for its cooling.
