“When you walk into a foundry, one of the things you are likely to see is a section of the building with rows and rows and rows of match plates with patterns on them,” says Howard Rhett, technical support leader for Viridis3D, of the sandcasting business.
These patterns are the copies of parts that they’ve made for other companies. They’re kept on hand so that the foundries can again pack sand around them to make a new mold when called upon to make the part again. “They have to make them, have to keep the stuff in inventory. The foundry is actually paying to keep these things warehoused,” he says.
