CONCRETE PRODUCTS & CAST STONEwww.cpi-worldwide.com CPI %u2013 Concrete Plant International %u2013 4 | 2025Numerous results of this work have already been presented at bauma 2025. These include weld-free and screw-fastened 3D-printed cores, which are used in grass paver molds, among other things. Maintenance, repair and replacement without grinding or welding, without distortion and with unrivalled dimensional precision. Another milestone is the machining-free production of tamper shoes with exceptionally detailed surface structures. These enable the reproduction of natural stone surfaces with a precision that conventional milling processes cannot achieve. This is complemented by 3D-printed components for core molds that are already ready for series production, such as grass pavers with completely new designs that can be produced using less material and are also individually interchangeable. This means that Kobra is already able to supply specific components for molds that are subject to extreme wear quickly and accurately. Examples include dummy joints in multi-level tamper heads or scratched parts in molds for dry wall blocks. But even special components that are required thousands of times over, which in the past tied up a lot of machine capacity or had to be bought in from suppliers, can now be manufactured using a wide variety of AM processes.Tamper shoes with embossed surfaces from the 3D printerFind us atCREATIVITYwww.kobragroup.comkobraformengroupkobraformenYour choice for more.Side by side with creativity.Combine design and function in your individual concrete block systems.
