EPM – Single Precision Moulding Machine

Installation on floor level, expandable to an automatic moulding plant

• stand alone and integrated moulding plant machine
• pitless installation on floor level
• expandable to an automatic moulding plant
• state-of-the-art compaction process AIRPRESSplus 2000
• reliable electronic control of the production process

„Premium Quality is produced even at a lower production rate. Upgrades to a total automation mode can be funded by the profits achieved by using the base high quality modules.“

Dimensional accuracy in casting production by:

Pattern Blowing:

Blowing of the pattern bolster including pattern plate located on the carriers on either left or right side of the moulding machine takes place prior to the transfer to the mould stripping and filling station.

Pattern Spraying:

Spraying takes place while the pattern shuttle is in filling position, by means of 2 spraying devices located on the left and right side of the filling device

Filling:

Shuttle device, the moulding sand is uniformly filled into the flask directly from the hopper discharge belt whilst the mould package is transferred to the compaction station.

Compaction:

One-stage or two-stage compaction process AIRPRESSplus 2000. 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.

Mould Stripping:

An electronically controlled, high- precision, hydraulic mould stripping device (deviation in height of the parting line diagonally max. 50μm) renders possible min. pattern draft angles of 0.15° even in case of extreme self cores (dia./length ratio 1:3)

Pattern Changing:

Pattern changing by means of carriers on the left and right side of the moulding machine. For changing the patterns and the pattern bolsters these carriers are transferred to the operator’s stand and return to their initial position after pattern changing.

Special Features:

• expandable from a stand-alone moulding machine to an automatic moulding plant for mass production
• no horizontal movement of the squeeze head
• 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
• SIEMENS S7 PLC with field bus Profibus being standard equipment, further PLC types available on request. Standard visualisation system based on SIMATIC WinCC
