Trockenreinigung mechatronischer und feinmechanischer Produkte und Komponenten

Das CO2-Schneestrahlreinigungs-Verfahren kann in unterschiedlichste Produktions- und Reinigungssysteme integriert werden. Je nach Kundenanforderung werden voll- und halbautomatische Systeme realisiert. Diese können Stand-Alone betrieben oder in verkettete Produktionslinien integriert werden.

Trockenreinigung mit CO2 ist für nahezu alle Werkstoffe und Reinigungsprinzipien einsetzbar mit einem ca. 40%-igen Kostenvorteil gegenüber konventionellen Verfahren.

Im Folgenden sind einige Beispiele aufgelistet mit denen wir Erfahrung haben. Sollten Sie etwas ähnliches oder auch Anderes haben wollen wir gerne mit Ihnen ins Gespräch kommen.

Degreasing and removal of lubricants

In order to achieve optimum results, it is indispensable for some processes, such as laser-welding, bonding or coating processes that surfaces are free of oil and grease. In practice, such surfaces are often contaminated with anti-corrosives, cooling snow-jet lubricants, polish residues, etc.

The CO2 technique permits critical areas to be selectively cleaned, e.g. welded seams or bonding sites. The excellent in-line capability and minimum space requirement of the system enables the cleaning process to be linked directly with the next process, excluding the risk of renewed contamination of components as a result of storage, for example.

CO2 snow-jet cleaning in laser processing

Today, the use of lasers in material processing is state of the art. A reproducible, clean and oil-free surface is essential in order to safeguard process stability, e.g. when laser welding. CO2 snow-jet cleaning can be automated in-line directly prior to the laser process and is thus ideally suited for cleaning such surfaces.

With common laser processes such as laser cutting or engraving, smoke residue is formed which impairs both the optical and technical properties of a component.

Smoke residue is removed rapidly and reliably using the CO2 snow-jet cleaning technique. Furthermore, by pre-cleaning surfaces with CO2 snow, the formation of smoke residue can be considerably reduced.

Removal of fine burrs

Burrs are often formed when precision components are machined or when plastic parts are manufactured using injection-moulding processes. CO2 snow-jet cleaning can be implemented as an automated process to rapidly remove tiny burrs.

CO2 snow-jet cleaning of sensitive or finely structured surfaces

Cleaning of sensitive and finely structured surfaces

The CO2 snow-jet cleaning process is not abrasive and can therefore be utilized for cleaning sensitive and finely-structured surfaces.

In plastics processing, the cleaning of moulds or forms is a fundamental task.

The mobile cleaning system 'JetWorker' enables the form to be cleaned in-situ, thus enabling stoppage times to be considerably reduced. The simple handling of the device permits uncomplicated and rapid cleaning between the individual processing steps.

In this way, the service life of moulds can be distinctly improved. In the same uncomplicated way, residue from cleaning agents can be quickly and gently removed.

CO2 snow-jet cleaning or bond pads in electronics

Cleaning of bond pads in electronic manufacturing

Very high demands are placed on the reliability of bond pads. However, certain demands are also placed on the cleaning of bond pads as far as the selection of a suitable cleaning method is concerned.

Locally-defined areas need to be cleaned selectively; at the same time, adjacent subsystems may not be damaged.

With a minimum jet dot diameter of currently 3 mm, the CO2 Snow-Jet process is able to do this. The process can also be automated and is dry, thus avoiding the need for expensive drying processes.

CO2 snow-jet cleaning of adhesive sites

Cleaning of adhesive sites

In order to improve the quality of adhesive bonding, adhesive sites are cleaned before the bonding process. 

Joint adhesive tests between acp – advanced clean production GmbH and Loctite GmbH have shown that the adhesive properties of surfaces which have been cleaned using the CO2 snow-jet cleaning are improved by a significant amount in comparison with cleaning using typical solvents.

Even with plastics such as polyethylene which are especially difficult to adhere, a marked improvement in adhering characteristics could be measured. Cleaning with CO2 snow-jet is fast, uncomplicated and can be automated.
