Ultrasonic welding machines

We develop, design and manufacture all of our ultrasonic welding machines, special-purpose machines, devices and components in Germany at our site in Henstedt-Ulzburg, close to Hamburg.

Every welding machine is subject to strict quality and functional testing. With these starting conditions, the flexibility of a medium-sized company and decades of experience, we offer our customers ultrasonic welding machines for efficient industrial production.

Ultrasonic welding, the energy-efficient technology for thermoplastics

Ultrasonic welding is one of the most energy-efficient technologies for joining thermoplastics. In contrast to purely thermal processes, microscopic movements of the sonotrode in the kHz range mechanically excite the joining zone during ultrasonic welding (German), resulting in localised heating.

The concentrated energy supply with outputs of up to 2,000 W melts the joining zone within fractions of a second. Sensitive peripheral areas do not heat up, the energy finds its way in a targeted manner. Almost as quickly as the plastic was liquefied, the melt solidifies again after the ultrasound is switched off. As a result, the welded components are immediately mechanically resilient.

Ultrasonic bench welding machines

With the TSM 20 bench welding machine, mth supplies a machine for joining components with a single joining zone. This process is used wherever large quantities need to be processed efficiently. For partially or fully automated production lines, mth supplies feed units and control systems that transfer the basic idea of the table welding machine to higher-level production cells. Areas of application for tabletop welding machines include toy parts, electrical enclosures, medical products such as infusion tubes, and much more.

Customised ultrasonic welding machines

Complex plastic parts with many welding points can be produced in large quantities if several welds are carried out simultaneously. Vehicle interior panelling and add-on parts in particular often consist of a large number of components that need to be joined with high repeat accuracy and process reliability. But also in the area of household appliances, for example, there are control panels, built-in parts or drive components that are assembled and welded together from different parts.

mth delivers the perfect solution for every application! Our special-purpose machines are as unique as the products for which they were designed. We are happy to advise you right from the design stage of your components in order to recognise potential welding challenges at an early stage and identify possible solutions.

General explanations about ultrasonic welding machines

Ultrasonic welding machines are key tools in modern manufacturing technology. They join plastics and other materials using high-frequency vibrations, creating a strong, homogeneous bond. These machines operate with precision and efficiency, making them particularly suitable for demanding industrial applications.

Furthermore, ultrasonic welding machines consist of other important components: ultrasonic generators, ultrasonic converters, ultrasonic boosters, sonotrodes, feed units and control units. These elements are integrated into our machines in a particularly compact and durable design to ensure reliable results and a long service life.

International presence through
established business relationships

mth develops and manufactures ultrasonic solutions for individual industrial requirements. Long-standing business relationships ensure that ultrasonic components, hand-held welding equipment, and special-purpose machines are used throughout Europe and internationally.
