In order to fully exploit the potential of the systems, Allweier has also invested in new cleaning baskets. The parts can be positioned in these containers to ensure maximum cleaning and drying performance. The task with which the company approached four manufacturers was: The parts must be placed and fixed in the basket in the best possible way for protection and rotation. This is because during the cleaning process, the baskets are swiveled and rotated by up to 360 degrees. At the same time, each basket should hold the largest possible number of parts without impairing the accessibility of the medium or the ultrasound to the parts and thus the cleaning effect. Also on the list of priorities was ease of handling. “The first phase involved containers for ten different parts. The companies received identical documents from us for this purpose. Even in the offer phase, METALLFORM clearly stood out from the other suppliers. For example, we received 3D design drawings of the baskets with parts in them and I could immediately imagine how the part would be placed and fastened in the basket. The consultation was and is also excellent. There is a lot of competence behind it and everything is properly thought out,” Thomas Schmidt explains the decision for METALLFORM Wächter GmbH.
In addition to various rigid, part-specific workpiece holders for so-called high demand parts, different partially and fully flexible solutions were realized. These are designed in such a way that they can be used simulaneously for different components or component families and can be quickly and easily adjusted by the operator during operation for the respective component to be cleaned. “METALLFORM provides us with optimum support in reducing the required number of workpiece holders through flexible solutions. We not only benefit in terms of investment costs, but also in terms of space requirements,” reports the technology planner. This includes, for example, a workpiece holder for ring housings made of aluminum with diameters between 240 and 320 mm and lengths of 20 to 100 mm. Here, displaceable prismatic plug-in rakes, which are inserted into basic carriers, enable the various parts to be securely held and fixed. At the same time, the part holders can be positioned in such a way that the workpieces only rest at non-critical points. METALLFORM developed a completely variable system for disk-shaped components with a wide range of diameters. It consists of two different inserts, one of which determines the number of compartment rows, the other the compartment depths. In this way, compartments can be formed in no time at all to securely hold the parts in a MEFO-BOX or the base frame. They are fixed in place by spring-loaded locking pins.
All workpiece holders and cleaning baskets are made of stainless steel round wire with an electrolytic polished surface. The round wire makes the parts easily accessible for medium and ultrasound from all sides. At the same time, optimum dripping behavior is achieved, thus minimizing dirt and media carryover. In addition, the round wire reduces the contact surfaces. And these can be selectively sheathed with Teflon tube in the form of clips to protect the components.
