The solution of METALLFORM’s design department consists of three part-specific workpiece holders into which the various parts are inserted. The component holders are designed in such a way that only the intended machine part fits into them. For small parts such as screws and grub screws, one of these holders was equipped with a bulk material basket.
The METALLFORM designers paid particular attention to the contact surfaces. The goal was to have as few and as small contact points as possible between the part and the basket. This is because every contact point carries the risk that contamination or cleaning agent will adhere to the part or that the machine components will not be completely cleaned or dried at the contact points. Direct metal-to-metal contact was prevented by encasing the contact points with Teflon clips. This solution has the advantage over coating as we can replace the clips quickly, explains the design manager.
To realize the required stackability and easy transport, the baskets were integrated into two 480 x 320 x 200 mm (L x W x H) and one 480 x 320 x 108 mm MEFO-BOXes. Thanks to their 16 mm high stacking frames the three baskets can be easily and safely combined into one batch, so that after cleaning and sterilization they are again completely available for installation in the splitting machine.
Both the workpiece holders and the MEFO-BOXes are made of stainless steel round bars with an electrolytic polished surface. The high-quality and durable material prevents return contamination from the basket to the component as well as contamination of the baths by corrosion and zinc deposits. In terms of workmanship, the customized cleaning baskets are also convincing: All rounds are completely welded together. As a result, there are no sharp corners, edges or loose wires anywhere that could cause injuries to employees when inserting the parts. “We are convinced that with these baskets we have received a first-class solution that is optimally matched to the requirements of our customer,” sums up Hans Laßnig.
