=====Description=====

[https://en.wikipedia.org/wiki/Sand_casting#Matchplate_sand_molding '''Matchplate Patterns'''] are made by assembling the two halves of a split pattern either side of a board.

'''Core Prints''', '''Runner''' and '''Riser Gates''' and '''Sprue''' locations can all be built on to the board as part of the '''Matchplate'''.

=====Matchplate Moulding=====

The '''Matchplate Pattern''' is assembled together with the '''Cope''' and '''Drag''' as shown and '''Parting Sand''' added.


Both sides of the '''Moulding Flask''' can then be packed with '''Moulding Sand''', rammed up and strickled off as for a normal '''[[Sand Casting]]''' procedure.


The main advantage of '''Matchplate Patterns''' is speed of moulding, which makes this a simple way of improving the process for quantity production.

* <span style="color: red">Ensure there are no trip hazards between the furnace and the moulding tray containing the flask.</span>
* <span style="color: red">Make sure that any tools introduced into the melt ''(e.g. to remove '''Dross''')'' are pre-heated and dry.</span>
* <span style="color: red">Wear full face shield, leather gauntlets and apron.</span>
* <span style="color: red">Use purpose made '''Crucible Tongs''' and '''Carriers''' to carry the [https://en.wikipedia.org/wiki/Crucible '''Crucible'''] to the moulding tray and pour.
