Weakness in logistics: Optimal technical cleanliness up to final assembly is only possible with the inclusion of transportation, storage, and unpacking

Microscopically small particles can significantly impair the functionality of sensitive components. In industries such as automotive, mechanical engineering, or micromechanics, where ever-smaller components are required, technical cleanliness is therefore becoming increasingly important. To ensure t…

At a joint appearance at this year's Motek, the so-called Arena of Integration, a total of 13 predominantly medium-sized companies presented a range of modern production technologies that were coordinated and interconnected according to the idea of Industry 4.0, thereby forming a comprehensive solution. (Source: Nerling Systemräume)

A demo system was set up, based on a conveyor system from Schnaithmann Maschinenbau GmbH. Surrounding this, the individual companies connected with their solutions, resulting in a complete system. (Source: Nerling Systemräume)

The overall solution featured a central control system that ensured the workstations passing through this conveyor system only held positions relevant to processes or applications that were pertinent to the individual component. (Source: Nerling System Rooms)

Examples include a semi-automatic labeling and marking system from Design & Engineering, a solution from Elabo GmbH for robot-assisted removal of a product to a repair workstation, or a system from Tekon Prüftechnik GmbH for process-safe and sensitive inspection of electrical contacts for contact systems. (Source: Nerling Systemräume)

A cleanliness area was also established on the conveyor band, where, for example, a cleanliness-sensitive assembly can be carried out under a clean air curtain. The system room experts from Nerling were responsible for ensuring the necessary conditions for this. (Source: Nerling System Rooms)

The pilot project Arena of Integration was initiated by the State Network Mechatronics BW. (Source: Nerling Systemräume)

To give the lower parts of arch printing machines in the Würzburg plant a highly fine finish, KBA acquired a DIXI 270 machining center from the Swiss manufacturer DMG Mori in 2015. (Source: Nerling Systemräume GmbH)

In order for the machine to maintain the required accuracy values of ± 10 µm, a temperature of 22 °C ± 0.2 K/h must be maintained in the machine room. To ensure these climatic conditions, KBA commissioned Nerling System Rooms GmbH to set up a precision manufacturing room with a pre-temperature room. (Source: Nerling System Rooms GmbH)

During the final packaging of endoscopic instruments, special attention must be paid to particle cleanliness. To be able to carry out this step in-house in the future, medwork GmbH set up a cleanroom facility in 2014. (Source: Nerling Systemräume GmbH)

The instruments must be packaged and sealed under cleanroom conditions according to GMP Class C. (Source: Nerling Systemräume GmbH)

The 16.90 x 16.88 m facility commissioned at Nerling is located in a newly constructed hall and includes, in addition to the actual cleanroom, a total of six airlocks. (Source: Nerling Systemräume GmbH)

Since Medwork considered a separate lock system for employees and materials to be particularly important, there are two locks each for personnel, material entry, and exit. (Source: Nerling Systemräume GmbH)

To ensure a flawlessly functioning process, Nerling medwork also supported the positioning of boxes and roll containers. (Source: Nerling Systemräume GmbH)

The instruments stored in boxes are transported via an elevator from the manufacturing area to the new cleanroom. Before being introduced, they undergo a cleaning process. (Source: Nerling Systemräume GmbH)

In the room itself, the employees perform a final wipe disinfection of the product and spiral it into a bundle, which is then inserted into the sterilization packaging. (Source: Nerling Systemräume GmbH)

The goods are then welded or sealed, labeled, inspected, and then released again. (Source: Nerling Systemräume GmbH)

Before the final processing step – sterilization – the re-packaging takes place, during which an instruction manual is included, the entire package is sealed, and it is labeled again. (Source: Nerling Systemräume GmbH)

The installation is visible from the training room next door. According to the color concept of medwork, all window frames and doors were designed in the company's color RAL 9007. (Source: Nerling Systemräume GmbH)

In the cleanroom, separate particle monitoring is carried out to meet the requirements of the OE area and to ensure operational safety. One of the two particle counters is installed on a column directly in the center of the room. (Source: Nerling Systemräume GmbH)

In the pre-series for the self-packaging at the beginning of 2015, medwork produced 5,000 products in the new cleanroom over 14 days. (Source: Nerling Systemräume GmbH)

Already in 2012, the laser technology experts at TRUMPF Werkzeugmaschinen GmbH + Co. KG installed a cleanroom facility at the Ditzingen location, where ISO 5 class flowboxes are used to assemble processing optics and laser beam guidance assemblies. (Source: Nerling Systemräume GmbH)

To enable the high purity class in the flow boxes and to keep all components as particle-free as possible, a comparable cleanliness class must also be maintained outside the boxes, inside the cleanroom cabin. The cleanroom is therefore classified as ISO 8 and has an additional assembly area of ISO 7 class. (Source: Nerling Systemräume GmbH)

The entire wall and ceiling system used at TRUMPF is freestanding. Additionally, the room system is modularly constructed, making it easy to expand and dismantle. (Source: Nerling Systemräume GmbH)

A 7-zone ultrasonic cleaning system is located upstream of the assembly and integrated into the cleanroom, transporting the cleaned material directly into the assembly room. It was procured parallel to the cleanroom and had to be incorporated into the planning. (Source: Nerling Systemräume GmbH)
