Tonnage refers to the amount of clamping force required to hold the two halves of a mold together during the injection of molten metal. This force is typically measured in tons and is essential for preventing the mold from opening due to the high pressure exerted by the injected metal. If the clamping force is insufficient, the molten metal may leak out of the mold, leading to defects in the final product.
