Abstract. The packaging device is the essential factor to determine the working efficiency and the packaging quality. The key technologies of the packaging device used for the multi-component moulding materials including the measuring-mixing system and the procedure control system were introduced and analyzed. It indicates that the measuring and mixing system composed of the volume measuring pump, the SK online mixer and the availably designed pouring valve is chosen after the comparison with the usually applied technologies. With the experimental results, the measuring accuracy can be limited to about 1% and the mixing units should be designed more than 32 joints. Furthermore, the main procedure control system is also displayed and described in detail in this paper.

Abstract. In order to resolve the problem of bubble defect after encapsulation, from the vacuum casting process requirements, the equipments were developed for the needs of production and scientific research. The development of the equipment adopts two schemes: final-mixed type and on-line mixing type. The equipment adopts compact design, automatic control, and easy to operate. The system functions of the prototype were tested and their technical indexes meet the design requirements. And the encapsulation parts encapsulated by the prototypes are tested to solve the bubble defect of the high-pressure module. Potting products have been detected, and it shows the two equipments effectively improved the bubble defects.
