Abstract

In order to control metering accuracy and homogeneity of the very small quantities of melt in micro-injection molding (IM) process, and combine the advantages of micro-IM with conventional injection molding, differential injection molding (DIM) method that uses conventional injection molding systems with a separate differential unit have been developed. The novel method can realize production of multi microplastic products. By using conventional injection molding with reciprocating screw injection systems, better plastication effect and mixing performance can be achieved. A planetary gear pump was employed as the differential unit; high metering accuracy could be achieved.
