Continuous rotary mixers are the central component in the model circuit.

Depending on the size of the moulds, the required throughput is determined. The quality of the moulding material mixture and the process reliability of the plant should come first here. The curing time can be kept nearly constant by selecting the binder system in combination with a powerful dosing control.

Optionally, automatic filling programs can be applied, which allow for quick and uniform filling of the mould.

A vibrating table serves for the mechanical compaction of the moulding sand at the filling station.

This is a platform which takes the mould on the model disc carrier when the roller table is lowered. 
The platform stands horizontally and vibration-isolated on rubber springs. Below the platform there are unbalanced vibrators installed.

These create vertical vibrations which make the mixed moulding sand flow. It distributes evenly in the mould and compacts.

Roller conveyors and band conveyors serve for the transport, buffering, and storage of transport pallets and moulding boxes. During model preparation, filling and hardening of the mould, these processes are coordinated by a control system.

To change between moulding lines, transfer cars are fitted with roller conveyors or band conveyors are used. 
The transfer car can be controlled either via a cable drum or a radio network.

A pin lift-off station is an effective and cost-efficient appliance for quick and secure separation of model and mould. 

It includes a lifting unit which rises parallely and horizontally. 
The steel pins inserted in the model frame are thus pressed upwards. The steel pins act on the moulding box frame or sand surface and press the mould upwards out of the model.

This solution ensures plane-parallel lifting of the mould and that the sand mould is not damaged when being separated from the moulding box.

Lowering turners provide the option to remove moulds automatically from the model.

The cured mould enters the turner. A transport pallet is pressed on it from above. The turner then turns by 180°. The transport pallet lowers slowly and moves the mould lying on it out of the model.

The function of a lowering turner can be realized with a "gym wheel" turner (see picture) or a C-turner.

For the handling of mould bodies and moulding boxes, various manipulation devices are required for secure and efficient manipulation.

These are characterized by a large width variance and are provided with hydraulic centre-of-gravity shifting. 
The horizontal position of the body / box can thus be set easily.
Frequency-controlled rotary drives apply the required torque via worm gears. 

In the compact controller, all parameters can be set and visualised.

Coating is usually applied after separation and post-curing of the mould. In the case of higher production rates and in order to achieve uniform coat thicknesses, the mould is flooded.

We provide coating stations for alcohol- and water-based coatings.
