Siegfried Hofmann GmbH, a developer of multi-cavity molds, and GROB-WERKE GmbH & Co. KG, a developer of producing methods and machine instruments, have collaborated on the manufacturing of a 3D printed aluminum mildew answer 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 – due to the usage of metallic 3D printing.
Because of GROB’s liquid metallic printing course of, it could 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 challenge. Preferrred for collection elements with fundamental floor high quality necessities, the light-weight molds are additionally the most effective answer for short-term prototype testing of supplies, spraying, and evaporation.
“We’re significantly 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 provide our demonstrator device 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 massive elements may be produced seamlessly. On the similar time, the excessive variety of steam nozzles ends in shorter cycle instances because of sooner heating and cooling processes.
Totally 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 Steel Printing course of, also referred to as Molten Steel Jetting, is characterised by excessive system flexibility, low element manufacturing prices, and excessive system reliability – which means that the method may be simply built-in into any present manufacturing setup.
