Study on the Mechanism of the Packing Process and Sink Mark in External Gas-Assisted Injection Molding
External gas-assisted injection molding (EGAIM) technology can be applied to effectively reduce the sink marks generated from the shrinkage of plastic parts. In this paper, the interaction mechanism of gas and melting during the EGAIM stage was discussed. The causes of the sink marks on plastic part...
