WebPlastic injection molding presses are classified or rated based on tonnage, or more specifically the clamping pressure or force. Presses can run in size from less than 5 tons of clamping pressure to over 4000. The higher the press ton rating, the larger the machine. A machine rated for 68 tons can deliver 68 tons of clamping pressure.
