| Abstract: | The operational principle of some metering units, such as leadscrew nut mechanism, pendulum bar type metering unit, metering pump, are introduced. The metering devices meet the requirement for the proportional mixing of two parts polyurethane system by controlled output. They have good precision, can be easily controlled and be realized automatization. |
