ABSTRACT:
A two-component molding system according to this invention has a pair of supplies each containing a quantity of a respective fluid synthetic-resin component capable of reacting and hardening with the other component. Respective conduits having upstream ends connected via pumps to the respective supplies and downstream ends connected via metering devices to a mixing chamber extend from these supplies. Molds are connected to the mixing chamber. A controller connected to the pumps and to the metering devices determines the pumping volume/time rates and compares them with the respective downstream actual volume/time rate at the downstream ends of the conduits. In the event that the actual rates are not substantially identical to the pumping rates, the controller sounds an alarm and shuts down the system.
