The Forge is the crafting table of the NPC Yamaha, in the Trade Center. It is not just for Upgrade Plates: it is where you craft several different kinds of item, each with its own recipe of materials. Plates are just the most used recipe, because almost everyone needs them to raise their equipment's Tier.
- Right click Yamaha and choose Forge.
- Pick the recipe for the item you need and confirm, if you have enough material.
