Ultrasonic welding is a precision technique for bonding metals and plastics. It is an established process used across sectors for diverse applications. The main aim of a powerful ultrasonic welding machine lies in its high-frequency approach to create a firm bond between materials under pressure. While joining there is no need for solder, nuts& bolts, or any other material to join.

RTUL Group is a major world supplier amplifying its frequencies to match customer needs. Our competency compels customers to repeatedly buy custom ultrasonic welders from our inventory. An ultrasonic hand welding gun can be ordered for specific applications. It is our pleasure to bring the latest technology to improve industrial functions with our experience and expertise.

Know how our product portfolio forms strong industrial bonds across fields like medicine, automotive, aerospace and packaging companies.

Diverse applications

 

• In the field of medicine, it is used to assemble delicate components such as surgical instruments, catheters, and implants.
• The packaging industry relies on ultrasonic welding for sealing plastic bags, pouches, and blister packs.
• In the electronics industry, it is employed to join components in printed circuit boards, sensors, and connectors.
• The aerospace industry utilizes ultrasonic welding for critical applications like joining metal sheets and creating components for aircraft structures.

 

Suitability factors

 

Ultrasonic welding for a particular application depends on:

• part size
• material compatibility
• cost-performance
• part requirements

Since it is a non-destructive process for joining materials, its diversity is on a large scale. Smaller parts can undergo ultrasonic welding, as the process is more efficient at generating heat in these areas. Material compatibility is crucial; certain metals, such as aluminium, copper, and titanium, are more amenable to ultrasonic welding than others.
Cost-performance considerations involve evaluating the initial investment in the welding machine, operating costs, and the quality of the resulting welds. Finally, part requirements, such as the desired bond strength, aesthetics, and production volume, should be carefully considered.

Custom requirements

 

An ultrasonic welding generator can be tailored to meet specific machinery needs. We work closely with customers, to design and build machines. Our engineers optimize these tools for applications. It involves checking the size of the welding chamber, the power output of the generator, and the design of the sonotrode and anvil.

Ultrasonic welding sonotrodes and boosters work together involving several components. It comprises of a sonotrode, a tool that transmits ultrasonic vibrations into the workpiece, and a booster, which amplifies these vibrations. The sonotrode is coupled with the workpiece, and as it vibrates at a high frequency, it generates heat at the interface of the materials, causing them to melt and intermix, forming a strong bond.

The steps are:

A power supply generator for high-frequency electrical energy.
Conversion into mechanical vibrations by a transducer.
Amplification by a booster to the sonotrode.
The anvil, or nest, provides support for the workpiece during welding.
A pneumatic head cylinder and actuator apply pressure between the sonotrode and the workpiece.

Choosing the right ultrasonic welding machine

 

Ultrasonic metal welding depends on the welding speed and types of materials to be welded. The bond strength is considered. The costing includes the purchase price, operating costs, and maintenance expenses. Technicians will also think about the power output of the generator, the frequency of the vibrations, and the design of the sonotrode and anvil.
