A match plate is a split pattern mounted to both sides of a flat surface that fits to a cope and drag. It can be complete with a gating system to save time.

The purpose is to speed up mold making.

In use, the match plate is placed in between the cope and drag and rammed with molding sand. The match plate is removed, the sprue cut, and the mold closed for pouring.
