Siegfried Hofmann GmbHA service provider with deep specialist knowledge in the injection form work works with Grob-Werke GmbH & Co. KG to provide a mold solution for particle foam.
Grand-Werke made their debut in 2022 with the aim of delivering a liquid metal pressure process, also known as Melted metal spray. The company previously built expertise in engineering and automation systems.
Since its introduction, the company has secret the material applications that can demonstrate the skills of its solution. With this cooperation with Hofmann you learn that the technology of Grob-Werke has contributed to producing the first foam in the form for a week to produce vom start of the design to the first foam.
The light forms ideal for series parts with basic requirements for surface quality are also the best solution for short-term prototype tests of materials, spraying and evaporation, explains Hofmann.
“We are particularly proud of the quick production of the additively produced aluminum foam shapes“, Says Stefan HofmannManaging Director of Siegfried Hofmann GmbH. “We only needed a third of the time to create our demonstrator tool compared to its 3D printed steel in the counterpart. “”
The shapes develop their maximum performance in combination with the Pearl. Machine particle foam formation Machine by Sigfried Hofmann. Up to 50 % porosity in form use ensures maximum evaporation of the raw material – even large parts can be generated without any problems. At the same time, the very high number of steam nozzles leads to shorter cycle times due to faster heating and cooling processes.
Finally, different form inserts for a product can be easily used with just one form frame. This saves costs and accelerates the production process.
