    摘要: A process of making a part with improved mechanical performance and improved impact performance compared to a solid part with a same weight by a disclosed foaming process. The process including introducing a glass fiber filled polymeric material to a hopper (128) of an injection molding machine, melting the glass fiber filled polymeric material to form a melt in a plasticizing unit (100), and pressurizing the plasticizing unit (100) of the injection molding machine with a blowing agent. The process further including dissolving the blowing agent into the melt, injecting the melt into a mold cavity (408) of a mold up to 100% of volume, and reconfiguring the mold to increase a size of the mold cavity (408) after a predetermined time after a delivery of the melt. A part made by the process and the device for making the part are also disclosed.
