A method, apparatus, and system for mixing a compounded material. A first selected amount of a base part for the compounded material and a second selected amount of an activator part for the compounded material to form a total amount of the compounded material is determined. The first selected amount of the base part is pumped by a pump system from a set of base part sources connected to the pump system into a container. The second selected amount of the activator part is pumped by the pump system from a set of activator part sources connected to the pump system into a container. The base part and the activator part in the container are mixed by a mixing system for a predetermined amount of time that is sufficient to activate the compounded material for use.

The bulk densities of a virgin material and a pulverized material are previously measured, based on pulverized material bulk density data related to the bulk density of the pulverized material and virgin material bulk density data related to the bulk density of the virgin material obtained by the measurement, a conversion coefficient for a predetermined molding condition when the virgin material and the pulverized material are mixed in a predetermined ratio is determined and registered. When the pulverized material is used, at least the bulk density of the pulverized material which is used is measured, and based on the pulverized material bulk density data, the virgin material bulk density data obtained by the measurement, and the conversion coefficient, processing for modifying the molding condition is performed.
