Ultrasonic welding technology

Plastics, Packaging, Nonwovens, and Metals

Ultrasonic welding means joining without adhesives, screws, or
heat from an outside source. During this process, material is
strategically melted by means of ultrasonic vibrations so that a
cohesive or form-fit joint is produced. As an economic production
method with short cycle times, ultrasonic welding ensures a large
degree of process control and repeatable quality results.

As a highly capable ultrasonic welding company, Herrmann Ultrasonics
offers the expertise needed to meet your specific machine, system,
and tooling needs. Our experience means we can develop machinery
to perform industrial plastic welding, vibration welding, and more.
In addition, we’re committed to our philosophy of “BONDING MORE
THAN MATERIALS.” That means that when you choose us, you aren’t just
getting expert ultrasonic welding machine manufacturers – you are
gaining a true partner whose success is tied to yours.

Automotive industry applications

A car is composed of far more than 10,000 individual parts,
many of which are made of thermoplastic materials.
Ultrasonic welding qualifies as the best suitable joining
technology for scenarios with large production
numbers of components:

  • High-strength and fast
  • Dimensionally accurate
  • Impeccable visual appearance

Medical industryapplications

AUltrasonic welding ensures maintained functionality
of the components and provides continuous process
monitoring unrivaled by other processes. Up to 130
different process reference data are available and
can be visualized

  • Stable weld process
  • Validated
  • Traceable

Electronic industryapplications

Sensors and electrical components are not only
used in industrial manufacturing but also in
automation engineering or in daily use. Ultrasonic
welding is particularly suitable for their production
and complies with product requirements, such as

  • High strength
  • Reliable functionality of components
  • 100% tightness

more +

Consumer industryapplications

Using ultrasonics, consumer components can be
produced and joined in a cost-effective way; at the
same time, the process provides great flexibility in
terms of design. High requirements for visual
appearance, production speed, or geometry are met

  • Light-weight and robust
  • 100% tightness
  • Mark-free surfaces

Packaging industryapplications

Food is better protected by good packaging and
kept fresh longer which is more sustainable.
Ultrasonic sealing technology has become an
established and economic alternative of heat

  • Absolutely tight seals
  • High output
  • Monitoring of seal quality

Hygiene industryapplications

Laminating without the use of adhesives and
embossing without the use of heat? The absolutely
clean ultrasonic technology for nonwovens makes
this possible. Materials are joined by means of
locally limited heat generation

  • Skin-friendly
  • Fast
  • Soft and yet stable

Due to soft welding by means of ultrasonics,
facial masks have a remarkably high wearing comfort.
Strong bonding of the multi-layer structure is
guaranteed by continuous processing, as well as providing
for high production rates.Fixation of elastic straps can be
easily realized.

  • High-strength and fast
  • Dimensionally accurate
  • Impeccable visual appearance

Nowadays, the requirements of battery products have become increasingly diverse and complex: In addition to precision, strength, and minimum particle formation, process validation and traceability are equally important quality criteria. Ultrasonic welding qualifies as the best suitable joining technology.

  • Robust and Fast
  • Repeatable High quality
  • Various solution for applications
