=====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 suitable way of improving the process for quantity production.
