Clean Endless Metal Tapes and Belts with Ultrasonic Inline Cleaners
Learn how ultrasonic inline wire and tape cleaners remove drawing soaps, lubricants, dust and residues from endless metal strips, belts, tapes and profiles with contact-less, high-speed cleaning and low chemical use.
Continuous Metal Production Needs Continuous Cleaning
Clean endless metal tapes and belts using ultrasonic inline cleaners is not just a cleaning task; it is a decisive quality step in modern continuous manufacturing. During drawing, rolling, slitting, punching, stamping and transport, endless metal materials accumulate drawing soaps, stearates, lubricants, grease, dust and fine particulate residues. Before downstream operations such as galvanizing, extrusion, welding or cladding, these contaminants must be removed thoroughly and reproducibly. Hielscher ultrasonic inline cleaners are specifically designed for continuous materials such as wires, cables, rods, tapes, tubes and stamped profiles, which makes the technology highly relevant for endless metal strips, belts and tapes.
This requirement becomes even more critical when the material is not a simple flat strip. Many endless metal products have perforations, punched contours, sharp edges, grooves or complex profile shapes. Ultrasonic inline cleaning is suitable for endless metal strips of various widths, sensitive and thin materials, sharp-edged metallic bands and complex stamped or punched metal belts. That is exactly the kind of geometry where conventional brushing or simple spray cleaning often leaves blind spots or creates inconsistent surface quality along the production length.

How Ultrasonic Inline Cleaning Works
The scientific principle behind ultrasonic inline cleaning is acoustic cavitation. Hielscher inline cleaners use ultrasonic transducers to introduce high-frequency sound waves into a cleaning liquid, typically around 20 kHz. These pressure waves create microscopic vacuum bubbles that collapse violently. Their implosion generates intense local mechanical forces and microjets in the liquid, which loosen tightly adhering contamination from the moving metal surface. At the same time, detached particles are dispersed into the cleaning liquid and flushed away, reducing the chance of re-deposition on the tape, belt or strip.
Because the cleaning action is physical and contact-less, ultrasonic inline cleaning can be intensive without being abrasive. Hielscher systems concentrate ultrasonic power into a very small liquid volume around the moving profile. This focused cavitation zone is one reason why high cleaning performance can be achieved in compact inline equipment that fits directly into existing or new production lines.
Key technological features include:
- Contactless cleaning: Cavitation removes contaminants without mechanical abrasion
- Focused ultrasonic energy: High-intensity cleaning in a compact liquid volume
- Modular design: Scalable ultrasonic power adapted to application needs
- Specialized sonotrodes: Engineered for continuous profiles and varying diameters
- Optional belt filtration systems: Reduce maintenance and prevent clogging
The use of intense acoustic cavitation enables Hielscher inline cleaners to efficiently remove oils, grease, dust, oxides, and fine particles–even at high line speeds–while maintaining material integrity.
Why Hielscher Inline Wire and Tape Cleaners are a Strong Fit
Our portfolio is designed around the reality of continuous production.
The compact WTC950 is only one meter long and combines an intensive ultrasonic cleaner with a temperature-controlled 17-liter stainless-steel tank, a pump for the cleaning liquid and an air-drying nozzle. The WTC950 can process wires, pipes, cables, strip and other profiles at inline cleaning speeds of up to 120 meters per minute.

For broader and more modular line concepts, the USCM cleaning modules such as the USCM700 are ideal. The USCM modules are stainless-steel systems that combine ultrasonic cleaning, liquid filtration, heating, recirculation and air wipes for drying, with inline processing at speeds of up to 200 meters per minute. The USCM700 is a powerful inline cleaner for endless profiles and as particularly suitable for removing heavy contamination such as drawing lubricants, soaps, grease, dust and process residues. The USCM700 is available with an optional fleece belt filter designed to reduce clogging and maintenance interruptions during continuous operation.

Suitable Endless Metal Materials
Compatible with ferrous and non-ferrous materials, including stainless steel and aluminum, as well as strips, tapes, cords, ropes, perforated strips and stamped profiles, ultrasonic inline cleaning is well suited to a broad range of endless metal materials used in industrial production.
- Endless metal strips, belts and tapes made from aluminium or steel
- Stainless steel perforated belts
- Endless punched or perforated metal strips with complex shapes
- Endless roll-cut metal straps
- Tension cords, ropes, braided wires and similar continuous metallic profiles
In other words, whenever a continuous metal product combines line-speed production with surface contamination and geometrical complexity, ultrasonic inline cleaning becomes highly attractive. That applies not only to standard strips and tapes, but also to sharp-edged metallic bands, perforated belts and formed endless profiles where residue removal must be thorough without damaging the substrate.

The Advantages of Ultrasonic Inline Cleaning for Endless Metal Tapes and Belts
- The most important advantage is cleaning quality. Cavitation reaches edges, grooves, punched openings and difficult-to-access surface features that conventional methods often miss. For endless metal tapes and belts, this means more uniform cleanliness across the full width and full production length of the material. Because the process is contact-less, there is no brush abrasion and less risk of mechanically affecting thin tapes, sensitive materials or sharp-edged profiles.
- A second major benefit is process integration. Inline cleaners are designed to sit directly in the production flow rather than forcing manufacturers into stop-and-go batch cleaning. The compact design, the focused ultrasonic power input and the availability of modular systems all support retrofit as well as new-line integration. For manufacturers, that means fewer interruptions, better synchronization with line speed and a more stable overall process window.
- A third advantage is reduced chemistry demand. Many applications can be cleaned with water alone or with only small amounts of mild detergents, e.g. low-concentration neutral, alkaline or acidic solutions. Aqueous ultrasonic cleaning as an environmentally favorable alternative to solvent-based cleaning when the required cleanliness level has been validated. This can reduce chemical handling, disposal effort and overall environmental load while still delivering strong cleaning performance.
- A Finally, ultrasonic inline cleaning offers measurable surface-engineering benefits. Ultrasonic cleaning can reduce residual particle density, improve surface wettability, enhance adhesion of subsequent coating systems and increase surface energy uniformity. On metallic substrates, these effects result in lower residual particle counts and improved downstream behavior. In practical terms, cleaner endless metal strips and belts support more reliable coating, passivation and further surface treatment, while helping reduce particle-related defects and quality deviations.

Frequently Asked Questions
What are the Process Steps of Endless Metal Profile Manufacturing?
In continuous strip, tape, and belt production, the material is commonly converted into an “endless” strip by welding coils together, then descaled by pickling, reduced to final gauge by cold rolling or other deformation steps, degreased, annealed if ductility must be restored, shape-corrected by temper/skin-pass rolling or tension leveling, and finally slit, punched, coated, lacquered, cut, or rewound according to the final product specification. For drawn endless profiles, the same logic applies: surface preparation comes first, then the profile is drawn through one or more dies, with intermediate cleaning or heat treatment added when required by alloy, strength, or dimensional accuracy.
What Soaps and Lubricants are Used for Rolling / Drawing Endless Profiles?
In dry drawing, the classical “soaps” are metallic soaps, especially sodium and calcium soaps, usually stearates or stearate-dominant blends; mixed sodium/calcium systems are also common. Experimental work on stainless-steel wire drawing shows that calcium stearate is better suited to lower drawing speeds, whereas sodium stearate performs better at higher speeds. Industrial drawing lines also use oils and greases, soluble lubricants, pastes, and surface-precoat systems such as borax, lime, or phosphate to improve lubricant pick-up and film formation. In rolling, especially cold rolling of strip and similar endless profiles, lubrication is usually provided by oil/water rolling fluids and other multiphase systems such as emulsions or water–oil mixtures, which reduce friction, force, and heat generation in the roll gap.
