The cleaning of parts has become a critical manufacturing step for quality in all industrial sectors. It takes a lot of effort to reproducibly meet particle and film cleanliness specifications. Cleaning should be done at the lowest possible cost and very durable. These contradictory requirements imperatively call for processes and machines adapted to specific needs.

From machine and plant construction, electrical and energy engineering to connection elements, the industry encompasses a multitude of sectors. The components of a wide variety of materials such as metals, plastics, ceramics and composites are manufactured and processed using very different manufacturing technologies. Products include cast and machined parts, stamped, bent, pressed and drawn parts, hydraulic parts and additively manufactured components. Although there are many parts, they have one thing in common: to ensure the quality of downstream processes such as machining, heat treatment, coating, gluing, assembly and to ensure lasting functionality, they require levels cleanliness in line with requirements. In many areas increasingly high demands on the cleanliness of particles and films must be met. Often there are additional challenges such as high flow rates and weights, a highly variable range of parts to be cleaned, short delivery times and low margins.

Adapt cleaning processes to the tasks at hand

This means that there are different requirements for cleaning parts. As a provider of future-oriented, flexible and energy-efficient complete solutions for cleaning industrial parts, Ecoclean covers the full range of wet chemical procedures. Cleaning processes and systems for batch or one-piece cleaning can be optimally matched to the respective specifications. Consider the material, size, geometry and weight of the part, the type and amount of contaminants, the downstream process and resulting cleanliness specifications and flow requirements. It can be determined whether the contaminants can be removed most effectively with a water-based detergent, an environmentally friendly solvent, or a modified alcohol with lipophilic and hydrophilic properties, allowing engineers to define the process and technology of best suited drying.

Appropriate process technology minimizes cleaning costs

To minimize the cost per part cleaned, it is necessary that the existing cleanliness specification is not only reliable, but also achieved quickly. The systems are equipped with various application-specific processing technologies such as spray, high pressure, immersion, ultrasonic and plasma cleaning, steam reduction, injection washing, deburring, pulse pressure cleaning ( PPC) and a passivation / preservation process.

By combining these cleaning procedures, the result and duration of cleaning for specific parts can be precisely influenced. The CPAP procedure combined with aqueous or solvent-based immersion cleaning reliably and quickly removes contamination from small cavities. In the case of complex and loose parts, the spraying and injection washing processes with nozzles adjustable between 10 and 16 bar also offer significantly improved cleaning results and shorter treatment times in solvent cleaning processes. .

Quality and cost can be optimized by combining processes requiring multiple machines in a single cleaning system, such as chamber machines designed for solvent-based or aqueous-based batch cleaning, with a subsequent low-pressure plasma process. . This method effectively and efficiently prepares the workpiece surface for subsequent coating or bonding. EcocleanThe wide product range also offers respective solutions for the precise deburring and cleaning of individual parts, for example hydraulic and motor components in one system.

Dry cleaning – selective or entire surfaces

Cleaning tasks also change with the evolution of manufacturing and assembly technologies. There is an increasing emphasis on dry cleaning processes, whether it is precisely removing film-like impurities from gasket surfaces, cleaning electronic components and assemblies, remove powder residues from additively manufactured components or clean integrated into the assembly. For this and many other applications, the equipment manufacturer has developed a special toolbox for cleaning processes with atmospheric pressure plasma, laser, CO2 snow, vacuum air conditioning as well as saturated and dry water vapor. Depending on the specific application, these “tools” are also applied singly or in combination.
