Siegfried Hofmann GmbH, a developer of multi-cavity molds, and GROB-WERKE GmbH & Co. KG, a developer of producing techniques and machine instruments, have collaborated on the manufacturing of a 3D printed aluminum mildew resolution for particle foam.
The molds are corrosion-resistant, and lighter than their stainless-steel counterparts – permitting for optimum vapor deposition, venting, and homogeneous filling. They’re sooner and extra versatile to fabricate – because of using metallic 3D printing.
Because of GROB’s liquid metallic printing course of, it may take as little as per week from the beginning of the design to the primary foaming within the mildew – relying on the complexity of the mission. Superb for collection elements with primary floor high quality necessities, the light-weight molds are additionally one of the best resolution for short-term prototype testing of supplies, spraying, and evaporation.
“We’re notably pleased with the speedy manufacturing of the additively manufactured aluminum foam molds,” stated Stefan Hofmann, Managing Director of Siegfried Hofmann GmbH. “We solely wanted a 3rd of the time to supply our demonstrator software in comparison with its 3D printed metal counterpart.”
The molds carry out optimally together with the BEAD.MACHINE particle foam molding machine from Hofmann. As much as 50 % porosity within the mildew insert ensures most evaporation of the uncooked materials – so even giant elements could be produced seamlessly. On the identical time, the excessive variety of steam nozzles leads to shorter cycle occasions as a consequence of sooner heating and cooling processes.
Completely different mildew inserts for one product also can simply be used with only one mildew body – saving prices and dashing up the manufacturing course of.
The GROB-WERKE Metallic Printing course of, also called Molten Metallic Jetting, is characterised by excessive system flexibility, low element manufacturing prices, and excessive system reliability – that means that the method could be simply built-in into any current manufacturing setup.
