DFM – Turntable Moulding Machine
Z-DFM – Twin Turntable Moulding Machinee

The fast turntable moulding machine

• for medium and high-speed moulding plants
• free access to the pattern equipment
• state-of-the-art compaction process AIRPRESSplus 2000
• reliable electronic control of the production process

„Classic sturdy turntable conception, easy access, proven design.“

Dimensional accuracy in casting production by:

Pattern Blowing:

Blowing of pattern and pattern plate takes place prior to the lifting into filling position

Pattern Spraying:

Spraying takes place when the mould package has been lifted to the filling position

Filling:

• Filling by means of the filling device transferred to the compaction and pattern draw station
• Weight-dependent dosage by means of load cells
• Uniform filling into the filling device by means of guide plates and a sand distributor flap
• Pattern-dependent filling by controlled opening of the hopper discharge shutters

Compaction:

• one-stage or two-stage compaction
• process AIRPRESSplus 2000
• TWINPRESS possible
• controlled and adjustable airflow intensity to ensure an optimum pre-compaction close to the pattern contour and at critical points
• active squeezing by a multi-piston squeeze head transferred to the compaction and lowering station, with separately adjustable squeeze force and squeeze time for the individual pressure circuits

Pattern Draw:

Pattern draw station with central and synchronised guide system for the lifting motion.

Pattern Changing:

Pattern changing takes place at the external position of the turntable. By means of a lifting table and the powered roller conveyors on the left and the right side of the lifting table a changing of pattern bolster including pattern within the cycle time is ensured.

Special features:

• all-hydraulic sealing of the moulding chamber by means of the synchronised lifting cylinders, thus avoiding wear on the contact surfaces
• low-maintenance design, good accessibility, with replaceable wear elements
• pre-tested sub-assemblies ensure shortest installation period and safe start-up
• all flask sizes available
• SIEMENS S7 PLC with field bus Profibus being standard equipment, further PLC types available on request. Standard visualisation system based on SIMATIC WinCC
