HPM – High Performance Moulding Machine
D-HPM – Double High Performance Moulding Machine
The fastest flask operating moulding machine in the world
- for high-speed moulding plants
- simultaneous filling and compaction
- state-of-the-art compaction process AIRPRESSplus 2000
- reliable electronic control of the production process
„Highest performance – no hopper and squeeze head transfer.“
Dimensional accuracy in casting production by:
Pattern Blowing:
Blowing takes place during return of the pattern bolster to the filling station
Pattern Spraying:
Spraying takes place when the mould package has been lifted to the filling position
Filling:
- By means of a stationary filling device > 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 shutter
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 stationary multi- piston squeeze head 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:
Within the cycle time, by means of two transfer cars and waiting positions in front of the moulding machine, with pattern bolsters circulating horizontally on a powered roller conveyor.
Special Features:
- no horizontal movement of filling hopper and squeeze head
- simultaneous filling and compaction
- low-maintenance design, good accessibility, with replaceable wear elements
- pre-tested sub-assemblies ensure shortest installation period and safe start-up
- SIEMENS S7 PLC with field bus Profibus being standard equipment, further PLC types available on request. Standard visualisation system based on SIMATIC WinCC
