In shakeout machines, the delivered green sand molding clusters are spread on an integrated grate using the micro throw technique. They are then broken open and the cast part is separated from the sand. In the process, sand lumps are effectively reduced in size and fall through the grate openings on an underlying sand conveyor as loose sand, where they are further reduced in size and then sent to be made into fine sand again.

The cast part is moved along the channel to the following process steps, cast cooling and sorting.


This is a classic shakeout machine with unbalance drives and fixed vibration angles between 45°and 80° that are adjusted to suit the process in question.


In the TUFE, the unbalance drives are specially arranged and the vibration angle of the machine can be varied with an electronic controller in order to suit the separation and conveyor behavior of different cast parts.


The TRF is a larger shakeout machine with a fixed vibration angle that is run by directed exciters and a three-phase current drive, instead of unbalance drives.


The TWFE machines are shakeout machines with an electronically adjusted vibration angle.

These proven systems are installed in large numbers in some of the most important foundries in the world.

As a rule, TWFE shakeout machines are used when sensitive cast parts need to be extricated. Regulated, high-energy vibrations are used to break down the sand lumps on the grate. The angle of pitch line vibration can be set to between 50° and 80° with the help of a potentiometer in the control cabinet.

Design parameters can vary greatly depending on the application

Shakeout machines typically have a width of approx. 800 mm to 2,000 mm and a length of between 2,500 mm and 7,000 mm

For modern high-performance molding facilities, systems with a first-stage shakeout and a main shakeout are often used in order to properly remove the flow of sand
