How does matchplate moulding work?

Matchplate moulding employs a plate with patterns mounted on both sides. The DISA MATCH moulding machine’s version of the process incorporates the unique DISAMATIC vertical blow/squeeze method, proven to optimally distribute sand, minimise pattern wear and consistently produce hard, accurate moulds.

The matchplate is positioned between the two mould chambers.	The mould chambers close.	The mould chamber assembly pivots 90° to line up with the sand hopper for a vertical sand shot.	Sand is blown down to fill each chamber and squeezed by multiple pistons to create the “drag” and “cope” mould halves. The patterns form impressions on each mould half.

The chamber assembly pivots back to horizontal and opens. The matchplate is removed. Any cores required are placed on the drag mould.	The chambers shut again to close the mould.	The complete mould is pushed out and placed on the conveyor. A jacket weight is placed around the cope before the metal is poured.

The matchplate process offers greater speed and mould accuracy compared to older horizontal techniques like jolt squeeze.

Matchplate moulding also offers very fast and simple pattern plate changes, making it perfect for short to medium-run casting production. DISA’s Quick Matchplate Changer (QMC) can change matchplates within two minutes.

Patterns designed for horizontal moulding machines can usually be transferred to matchplate moulding machines with little effort. Likewise, matchplate patterns designed for one brand of machine can usually be employed on a DISA MATCH with minor modifications or using a simple adapter frame.

These enclosed machines create a cleaner, quieter and safer foundry working environment.

The DISA MATCH moulding machine’s flexibility and precision means it can cope with diverse moulding types and volumes. It is suitable for short to medium-length runs of ferrous, aluminium, copper and other metal castings.
