APM – Pattern-Draw Moulding Machine

Best possible moulds even in case of small series

• pattern bolster and pattern in outer position
• different modes of pattern changing
• good sand distribution
• low-cost alternative, expandable to an automatic moulding plant
• state-of-the-art compaction process AIRPRESSplus 2000
• reliable electronic control of the production process

„4 simple steps to a perfect mould."

Dimensional accuracy in casting production by:

Pattern Blowing:

Blowing of the pattern and the pattern plate after pattern draw and before lifting to take over a new flask and filling frame

Pattern Spraying:

Spraying takes place in the compaction station, after taking over the flask and the filling frame, during lowering of the mould package. Spraying may also be effected manually if the mould package is off the squeeze station.

Filling:

The moulding sand is filled uniformly into the mould package located at the external pattern changing station directly from the hopper discharge belt via a feeder provided with guide plates.

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 means of a stationary multi-piston squeeze head with separately adjustable parameters

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 by means of a hoist; expandable up to a fully automatically operating pattern changing system.
• low-maintenance design, good accessibility, with replaceable wear elements
• pre-tested sub-assemblies ensure shortest installation period and safe start-up

Special Features:

• expandable from a stand-alone moulding machine to an automatic moulding plant
• no horizontal movement of the squeeze
• controlled and adjustable airflow intensity
• TWINPRESS possible to ensure an optimum pre-compaction
• close to the pattern contour and at critical points
• active squeezing by means of a stationary multi-piston squeeze head with separately adjustable parameters
• 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
