Industry solutions

Ultrasonics for industry & food

Our G1226 and custom sonotrodes open up two highly attractive industries.

Bulk goods industry

Bagging & packaging lines

Flour, sugar, fertiliser, granulates – ultrasonics produce tight seams in seconds, even in dusty sealing areas.

The advantageUltrasonics weld straight through contamination – heat-sealing jaws fail here.

Food industry

Food & net packaging

Ultrasonics seal without contact and without residue – with no heat transfer to the product.

Hygiene advantageNo exposed heating elements, HACCP-compliant integration possible.

Frequently asked

FAQ

The most important questions about our services – answered concisely.

Which ultrasonic generators do you offer?
We manufacture CE-compliant generators from 300 W to 1200 W in the 20–40 kHz range. Our newest generator is the G1226 (successor to the G1220) with 1200 W / 20 kHz – designed for continuous use in packaging lines. In addition we offer portable units such as the G300F40 and laboratory generators.
Do you also repair other manufacturers’ equipment?
Yes. Besides our own units we repair ultrasonic generators and converters made by Albert Früchtling GmbH, HERFURTH GmbH and Herfurth UK Ltd. During the repair we can provide a loan unit (G300F40) at special rates on request.
How old can the equipment you repair be?
Age is no exclusion criterion for us. Units 20 years and older come back to us regularly – from Germany and from abroad. When spare parts are no longer available on the market we rebuild assemblies or upgrade to current technology.
What is STEER.E and how does it work?
STEER.E is our business line for e-mobility, charging infrastructure and EPC management (project management as a service). We take over the complete project management – as main contractor or on your behalf under power of attorney. All details are on the dedicated website: steer-e.de.
Do you also take on individual metalwork jobs?
Yes, absolutely. We manufacture single parts and small batches in stainless steel, aluminium, brass, bronze and Makrolon. From sheet metal work through welded assemblies to complete assembly production including electronic components.
How do I reach you when production has stopped?
Call us directly on +49 (0)40 / 853321-0. We prioritise your enquiry in the event of production stoppages and urgent repairs. Available Mon–Fri 8:00–17:00.
Do you have open positions?
Yes. We are currently looking for a metalworker/fitter/welder (m/f/d) and an electronics technician/ultrasonic service engineer (m/f/d). Part-time, full-time or mini-job – retirees are very welcome too. Simply write to jobs@wwtec.de. View the positions →
