The photos above show the top and bottom halves of the match plate pattern.

• The patterns are machined out of urethane plastic block.  The urethane patterns wear better than wood and are less expensive than aluminum.  The urethane patterns can also be easily modified by back-filling and machining.

• The urethane patterns are attached to the aluminum match plate.

The top and bottom halves of the mold are formed by packing green sand around the match plate in the metal mold boxes.
