In injection molding, the projection area of the plastic part on the parting surface of the injection mold is the main factor affecting the clamping force. The larger the value, the greater the clamping force required. If this value exceeds the maximum molding area allowed by the injection molding machine, the phenomenon of die swell and overflow will occur during the injection molding process.

Whether the total amount of injection mold required by injection mold design is closely related to the maximum amount of injection mold required for injection mold design.
