Ultrasonic cleaning - Import export

Sound waves generated by an oscillator agitate the wet medium. This leads to cavitation bubbles that implode at a high frequency and result in hydraulic impacts. These impacts combined with microflows flush particles and pigments off the parts. The costs of ultrasonic cleaning are primarily determined by the processing time. Low ultrasonic frequencies remove coarse dirt, while high ultrasonic frequencies are used to eliminate fine dirt from parts.

WIWOX® CORUS HD ultrasonic systems have been specially designed for cleaning high-quality moulds and precision tools. In maintenance these replace the labour-intensive and often ineffective manual cleaning. The ultrasonic cleaning process can be used for all metal moulds, in particular tools for injection moulding, extrusion, rubber processing as well as aluminium and gravity die casting. A typical structure consists of three stages: 1. cleaning, 2. rinsing and 3. passivating. The usable dimensions are matched to common mould sizes. The workpieces to be washed are placed in the tank either with the aid of a washing basket or with a lifting beam. Our ErgoStation is recommended for manual rinsing, drying and post-treatment. The working area is completely enclosed, brightly illuminated and ventilated. Operation is safe and simple, as the moulded parts are loaded laterally through a sliding door and held by a lifting device during treatment.

The WIWOX® VERSA GENIUS+ ultrasonic cleaning system enables individual, demand-oriented mould and parts cleaning. The modular design allows adaptation to almost all process requirements. Later expansion or automation is possible at any time. WIWOX® VERSA GENIUS+ ultrasonic cleaning systems consist of washing, jet, rinsing and drying modules as well as the corresponding accessories. The spectrum ranges from individually operated cleaning basins to fully automated, multi-stage cleaning lines. WIWOX® VERSA GENIUS+ sets new standards in modern plant design. Well thought-out details in the area of guiding the cleaning medium, agitation and process control ensure a flexible and energy-efficient process sequence that meets the requirements. You can convince yourself of the economic efficiency of the system by extensive cleaning tests in our test laboratory. The bath care accessories also play an important role in the cleaning result, the uniform process flow and the operating costs.

The WIWOX® USm Ultrasonic cleaning tanks enable individual, demand-oriented surface treatment in a single or multi-stage process. The modular design allows adaptation to almost all requirements and subsequent expansion or automation is possible at any time. Aqueous cleaning at temperatures between 60° and 80° C ensures absolute degreasing and particle removal. Organic or inorganic residues such as polishing paste, paint, plastic, release agents, oil carbon or lime can be easily removed by using the right cleaner. The workpieces are cleaned within a few minutes. The cleaning result is always perfect and reproducible. The subsequent rinsing process is followed by stain-free post-cleaning or preservation. The WIWOX® ultrasonic cleaning process can be used for all steel moulds as well as brass and copper parts. Especially tools for injection moulding, extrusion, rubber processing, aluminium die casting and gravity die casting.

WIWOX® 340 is a weakly alkaline cleaning agent for grease, oil and oil carbon soiling. Very suitable for pre-cleaning or basic cleaning of soiled steel, cast iron and non-ferrous metal or plastic parts in an ultrasonic bath or in a spray cleaning system. After cleaning and without water rinsing, the parts are temporarily protected against corrosion. The final drying can be accelerated by blowing off with compressed air, a warm air flow or treatment in a drying cabinet. WIWOX® 340 can be used in a concentration of 5 – 7 %. Dilution with water depends on the degree of contamination and the intended exposure time. The bath should have a temperature of approx. 60° C. The bath should be kept at a constant temperature. In the field of precision mechanics, longer exposure times are possible depending on the degree of contamination.

WIWOX® 250 is a very alkaline cleaning concentrate for organic (oil, coal, grease etc.) and inorganic (magnesium, lime etc.) residues on tools and moulds. It can be rinsed off residue-free without a film on the surface. The concentration depends on the working conditions, the degreasing time, the degree of soiling, etc. (between 5 – 30 %). Regular replenishment by checking the bath can prolong its service life. In contrast to powder concentrates, lthe iquid formulation allows convenient use without danger of exothermic reaction in the plant.

WIWOX® 410 is a liquid, alkaline mould cleaning agent for the removal of burnt rubber and plastic residues from metallic surfaces. It is also used as a paint stripper. WIWOX® 410 is used undiluted for immersion cleaning of metal moulds. The construction material for the tank can be sheet steel or stainless steel. The tank size depends on the moulds to be cleaned. The pool can be heated from the outside or inside by a heating coil. The processing temperature is generally approx. 80° C. The processing time depends on the degree of soiling and the type of soiling between 10 – 30 minutes.

Ultrasonic cleaning tanks of series SW 12, SW 25 and SW 40 are compact tabletop cleaning devices for industrial purposes. The serial version includes a cover with handle. The cleaning tanks can be equipped alternatively with frequencies of 30 or 40 kHz or in combination 30/40kHz. On the front the ultrasonic operation can be set nonstop or for a limited period. The ultrasonic generators are integrated in the stainless steel housings. The devices are equipped with a heating with thermostatic regulation installed at the outside of the tank. It is set on the front. The tanks are made of stainless steel, here the SW40 – SW90 are built in welded design. On the bottom they have a residual clearance. Heated and cold cleaning tanks complete the program. Only aqueous cleaning agents are permitted in the cleaning tanks.

KLN ultrasonic generators are incorporated in cleaning tanks of various capacity from some liters up to several cubic meters. They have a high operating reliability also under extremely difficult application conditions. Based on decades of experience in developing ultrasonic generators today we have a broad variety of generator series, meeting the most various requirements concerning frequency, way of installation and output power.
