Technical cleanliness process chain - your way to optimum component cleanliness
The technical cleanliness process chain plays a decisive role in industrial production in order to ensure the functionality and durability of components. But how can the required component cleanliness be achieved and verified in the process? At the joint stand of the Competence Network for Industrial Component and Surface Cleaning Leonberg e.V. (CEC), visitors will gain a comprehensive insight into practice-oriented solutions and interrelationships.
The central process step for achieving the required component cleanliness is the cleaning process. Various technologies and process chemicals are used, which are specifically tailored to the requirements of the components and their geometries in advance. Physical processes such as ultrasonic cleaning, high-pressure cleaning or steam degreasing as well as chemical cleaning methods based on aqueous or solvent-based processes ensure the desired cleaning result. Combined processes are also frequently used to remove both particulate contamination and filmic residues such as oils and greases.
Regular monitoring of the cleaning baths is necessary to maintain a constant cleaning performance. Important parameters such as the degree of soiling, the concentration of cleaning agents and the pH value are checked.
After cleaning, the components are often packed, which is essential for logistics processes, in special, low-particle packaging concepts that are individually adapted to the components in order to protect them from recontamination or corrosion until the next application.
During the process, the component cleanliness is verified after cleaning. A distinction is made between particulate and filmic contamination. Standard methods such as cleanliness analysis in accordance with VDA 19.1 and material analyses are used for particle measurement in order to determine the particle sizes and quantities as well as the material types.
Methods such as fluorescence measurement or FTIR spectroscopy are used to detect filmic contaminants in order to identify residues such as oils or greases. The data is documented and serves as the basis for quality assurance and the associated permanent compliance with the specified cleanliness limits.
Another key aspect of maintaining component cleanliness is controlled environmental conditions such as clean rooms. Depending on the requirements, different room concepts are used, which correspond to cleanroom class ISO 7 or ISO 8, for example. These controlled environments minimize the risk of recontamination of the cleaned components.
At the joint CEC stand at parts2clean, visitors will receive a compact and practical overview of the various solutions and technologies required to ensure technical component cleanliness. From cleaning steps and cleanliness control to cleanroom solutions and quality assurance methods, companies will find all the information they need to meet their specific cleanliness requirements.
In addition, the CEC offers comprehensive technical information on technical cleanliness and introduces its network: In the CEC network, members benefit from regular events and exchange formats as well as industry trend studies and working groups on current and future challenges in technical cleanliness.
