Safe and efficient sand core production

Without complicated and expensive heating devices

The ACS technology – one step further

Using innovative materials developed by us for the core boxes, we use the electrical conductivity of inorganic binders for conductive and thus geometry-independent homogeneous heating in the core box. The cores harden from the inside out without forming shells. The recording of the electrical parameters in real time allows for the first time an real monitoring of the curing process and thus fulfils the requirements for a digitalisation of the process. 

Layout of the ACS module

Our development can be installed on all existing core shooters. Thereby the core box module is essentially replaced.

The focus still is on the highest quality of the cores to be produced (1). To make this possible, we use special materials for the core boxes (2), whose electrical conductivity we adapt to the conductivity of your inorganic binder. If a voltage is now applied to the system in the form of electrodes (3), a homogeneous flow of current through the core box and the shot sand binder mixture results, as a result of which the core is conductively heated and curing begins. Highest safety standards isolate the module from the rest of the system (4) and ensure a safe production

Upgrade of existing core shooters

Our technology can be used on all existing core shooter systems. We replace the existing core box technology with our core box modules, which are manufactured from materials developed by us. Depending on the quantities to be produced, we have various materials available from which we select the right one for you in consultation with you. Together with the required control technology, you will receive a total solution that increases your efficiency while reducing your costs and energy consumption. And all this at a significantly lower price than a new complete core shoting machine.
