Ultrasonic metal welding is appropriate for the assembly of similar and dissimilar non-ferrous metals.

The primary advantage of this welding technique is that it provides exceptionally short welding times, no filler metals requirements, very low electrical contact resistance and helium-tight welds. Surfaces that are suitable for this type of welding are limited to small areas and restricted to points, line or circular weld patterns.

We Cut & Seal With Precision

Ultrasonic energy has found extensive use in cutting of textiles, woven sacks/plastic etc and their downstream processing. Many of these uses are based on the ability to use ultrasonic energy to induce heat and pressure by vibratory action.

The use of ultrasonic Cut n Seal technology makes manufacturing of non-wovens and wovens, economical and process-safe and our customers from the medical, packaging, fabrics and engineering industry value it tremendously.

With our ultrasonic cutting and sealing technology, we are able to separate precisely and expeditiously, and weld edges in a refined and reliable way. The principal advantage of the ultrasonic seal and cut method is that the edge of the textile material, while being cut simultaneously, is sealed by the dissipation of ultrasonic energy, thereby preventing the presence of a frayed edge or the unraveling of threads, no discoloration of fabric and very strong, uniform, smooth, clean and long lasting edges without over thickness with low energy consumption.

Method Of Ultrasonic Cleaning

Ultrasonic cleaning is used in different industry branches. Ultrasound travels in liquids in form of a longitudinal wave. These longitudinal waves produce areas with overpressure and vacuum which have influence on the evaporation of the liquid.

A liquid is conjoined through cohesions. If the intensity of ultrasonic intensity is increased in the liquid continuously, the liquid will partially evaporate in the vacuum phase and microscopic tiny steam bubbles emerge.

In the following overpressure phase, the steam bubbles implode (cavitation). In this procedure, extreme high forces arise leading to micro blast waves and micro streaming.

The cavitation is influenced by a lot of parameters. It is depending on the external pressure, the temperature, the sonic frequency and intensity, the type of liquid and other sonic values.

Finally, the cavitation causes an excellent cleaning effect comparable to the attack of countless micro brushes.

Advantages of Ultrasonic Cleaning

• Easy handling.
• Shorter cleaning time.
• Less chemistry.
• Low cleaning temperatures.
• Reproducible result .

Portable Ultrasonic Flaw Detectors

"Among the non destructive testing methods for internal defects, Ultrasonic testing is the fastest and most reliable method. With this one can save on material, labour, machine cost & time, by early detection of defects at raw material stage.

RTUL’s Portable Ultrasonic Flaw Detectors provide a very user-friendly flaw detection technique to analyze blow holes, porosity, inclusion & any types of flaws.

High frequency sound waves generated by piezo electric transducers enter the object to be tested and get reflected at the interphase of defects such as cracks, blow holes, inclusions, porosities, lack of bond etc. The reflected echo is displayed in form of peaks on screen of ultrasonic flaw detector. The amplitude and position of these peaks give useful information regarding the location, shape & size of the defect.

We have TRANSFORMED sieving

With our high tech ultrasonic sieving equipment we have transformed conventional sieving procedures. Not only can the screening process be accelerated radically (Up to 30 times) also the mesh quality and its lifetime can be increased. Also you improve your throughput and the quality of your products.

In addition to the conventional method, " SONOSCREEN" ultrasonic supported sieving technology evenly transmits as oscillating motion, in the micron range, onto the screen surface reducing the friction between the sieve mesh and bulk material. This Enhances the throughput and quality of your present vibratory screener, sieve or sifter.

Our revolutionary ultrasonic powder sieving system can be applied to your existing sieve, screener, or sifter to eliminate blockage or screening of wire mesh while sieving powder products such as powdered metals, ceramics, powder coatings, pharmaceuticals, or food additives.

Depending upon the particle structure this reduction can result in a significant increase in throughput volume. Screen blinding and clogging are also reduced due to the cleaning effect the oscillating motion has on the sieve mesh. A consistent efficient production process is guaranteed while simultaneously reducing the related maintenance costs to a minimum." SONOSCREEN" can be applied to both wet and dry sieving applications.
