Press Release The optimum in both cleanliness and profitability Flexible cleaning baskets deliver 50 % cost saving The demanding cleanliness requirements placed on modern hydraulic parts can only be efficiently fulfilled with the aid of partspecific cleaning baskets. The enormous variety of parts produced by manufacturers of hydraulic components therefore forces them to use a large number of different workpiece holders. A flexible solution developed by Metallform now makes it possible to decrease the number of cleaning baskets required, thus leading to a reduction in investment costs of around 50 % when compared with conventional fixed-shape cleaning baskets. The smooth operation of a hydraulic system requires each individual part to fulfil demanding requirements in terms of residual particles. This is ensured with the aid of corresponding cleaning machines. It is to be noted here that cleaning baskets have a decisive influence on the speed, reliability and profitability with which the required level of cleanliness is achieved. In particular, they must ensure that the part is properly exposed to the cleaning media and the mechanical applications of the cleaning machine (e.g. ultrasonics, injection flood washing). on all sides. Workpiece holders therefore tend to be part-specific. In the case of contract manufacturers and companies with a broad or highly dynamic product portfolio, this is linked to substantial investment in cleaning baskets. Furthermore, diminishing product life cycles mean that such investment is required at increasingly short intervals. Another issue is the considerable amount of basket storage space required. Using flexibility to reduce costs This was the challenge that faced a prestigious manufacturer of hydraulic systems, which required new cleaning baskets for around 50 different valve manifolds. If the company had tackled this task with the aid of a conventional solution based on bespoke workpiece holders for 1/4 each part, it would have needed around 600 workpiece holders in order to cover the entire production process. It is a different story with the flexible solution developed for the company by Metallform, which is based on the dimensions of the various components on the one hand and their respective batch sizes on the other. Instead of relying on fixed-shape workpiece holders, Metallform designed multi-purpose base racks and adjustable lids along with a variety of inserts tailored to the dimensions of the various valve manifolds. This makes it possible to quickly and easily create compartments within the base racks which securely hold the parts. The inserts are fixed into the base racks using spring steel sheets. The size of the base racks is adapted to the charge dimension of the cleaning machine (a standard dimension). The components are fixed in the workpiece holder using lids which can be set at various heights. This makes it possible to compensate the different component heights. This flexible solution not only drastically reduces the number of cleaning baskets required, but also decreases investment costs by around 50 %. In addition, the hydraulics manufacturer is now perfectly set up for future developments: In the event of a change in its product portfolio, the base racks and lids can continue to be used and only the part-specific inserts need to be replaced. If any future parts require special protection at contact points, this can be realized with the aid of targeted Teflon tubes. Another benefit delivered by the flexible system is the limited amount of storage space required: If specific manifold variants are currently not in production, only the inserts for those components need to be stored – and not the workpiece holders in their entirety. The multi-purpose base racks and lids remain in constant use in combination with the corresponding inserts. Stainless steel rounds for optimum cleaning characteristics Metallform manufactures all base racks, lids and part-specific inserts from electropolished stainless steel rounds. The same applies to all the company’s cleaning baskets, for example the MEFO-BOX system. The smooth material and open design of the cleaning baskets ensure that 2/4 components are properly exposed to both the cleaning media and mechanical applications of the cleaning machine – for example ultrasonics or injection flood washing – on all sides. Good drainage behaviour also minimizes particle transmission and reduces drying times. In addition, the high quality of both the material and the processing thereof ensures that the cleaning baskets are characterized by durability and ergonomic handling. MEFO-BOX – a cleaning basket system with added value Developed by Metallform and available ex stock, the MEFO-BOX system can be used in a variety of scenarios thanks to its wide range of cleaning baskets and accessories such as inserting bottoms, lids (supporting, clamping or adjustable), compartment rods and separators as well as bulk material baskets. It can also be expanded to include bespoke elements where required. It is available in various series and compatible with standard commercial goods and transport boxes.
