In conjunction with the system tamper heads, this results in a cost advantage that is noticeable over the entire service life. Instead of completely replacing a worn mold, only the wear parts are replaced in Kobra molds. The trained maintenance engineer at Al Wady immediately recognises the added value of this bolted construction in daily handling: It offers the stability of a solid mold combined with the flexibility of a modular system.Innovation through dialogue: The leap to additive manufacturing (AM)The development of ISO stone molds shows that the exchange between Kobra and users is not a one-way street. These were created based on direct feedback from maintenance personnel. The biggest challenge was handling: Lifting and turning heavy molds for minor repairs is time-consuming and poses safety risks.Kobra's solution was a radical redesign with a focus on easy accessibility. Critical wear parts are accessible from above, allowing them to be replaced directly in the machine. Additive manufacturing (AM) plays a crucial role here. By using 3D printing technologies in metal processing, Kobra achieves a new dimension of precision in reproduction.A crucial advantage: Wear parts manufactured using AM exhibit particularly high dimensional accuracy. This makes it possible to manufacture spare parts so precisely that they fit into existing frames without any reworking. This precision in reproduction is another key to reducing maintenance costs, as the accuracy of fit is guaranteed even after years of use of the base frame. The combination of electronic measurement and additive manufacturing makes the Kobra mold a digital twin of itself that can be perfectly complemented at any time.Conclusion: Appreciation as an economic factorThe collaboration with customers such as Al Wady impressively demonstrates: A tool is only as good as its user.
