New and highly effective Core-Drying Technology developed by KRÄMER+GREBE

New and highly effective Core-Drying Technology developed by KRÄMER+GREBE


Currently, casting foundries mainly employ the polyurethane cold-box process to manufacture cores while inorganic core-making processes are gaining popularity. During the cold-box process, the reaction and the accelerated curing of the core are set off through the addition of a catalyst mixed with a carrier medium.

In inorganic core-making, however, this curing process is replaced by heating and purging with hot air, which causes water to evaporate and moisture to escape from the core box. It is a more complex and time-consuming process that is related to sand casting and curing, and is therefore subject to certain restrictions. This means that there are limitations on void spaces and geometry during inorganic core-making processes. Nevertheless, a compromise can be found between core filling and core curing.

A process newly developed by KRÄMER+GREBE can be used in such cases for better core-drying performance. The Core-Drying Technology is integrated into the core box and can be fitted in new or existing moulding tools.

Come take a look for yourself and visit us at the booth of the company Laempe Mössner Sinto (Hall 17, Booth B40). On a Laempe LHL30 core shooter, you will be able to find a cold box equipped with our Core-Drying Technology. We will be delighted to explain to you in person the advantages of this innovative technology.

Engineering – tooling – casting – 3D measurement technology in product development

The quality of a cast product is significantly influenced by the corresponding injection moulding tools and core boxes. Due to the direct connection to the subsequent product, an optimal tool design is an essential factor in determining later success. Therefore, state-of-the-art simulation applications and 3D measurement technologies are used nowadays to aid in the engineering and manufacture of tools.

Especially in the development of cast products, it is not uncommon for the tool to be a critical factor when it comes to keeping the time to market as short as possible. At GIFA 2019, KRÄMER+GREBE will be presenting the latest methods for developing and manufacturing tools. The latest CAx tools, analysis methods, manufacturing technologies and digital technologies are used in everything from product idea development to optimisation loops to maintenance and lifetime extension.

Inform yourself at the GIFA on this interesting topic during a previous lecture of our specialists during the break-out session of the company GOM on the 26th and 27th of June – 14 p.m. in Hall 10, room 10.1 A.

During the trade fair, we will also be delighted if you would take the opportunity to visit our company premises in Biedenkopf-Wallau. Arrange an appointment today and come have a look at our revolutionary new development as well as our comprehensive service portfolio.
