Abstract
A lever pivoted at a support point receives force from pressure receiving members located at two positions along the direction of flow of resin in a flow passage without a metal mold. A physical property or condition of the resin flowed into the metal mold is determined as a function of the time during which the resin flows between the two pressure receiving members and of a difference pressure acting on the lever at the two positions.
