摘要： The disclosure is directed to a solid part, and a device and process of making the solid part. The process includes introducing a glass fiber filled polymeric material to a hopper of an injection molding machine, where the glass fibers have a pre-molding length, melting the glass fiber filled polymeric material to form a melt in a plasticizing unit, pressurizing the plasticizing unit of the injection molding machine with a blowing agent, dissolving the blowing agent into the melt, injecting the melt into a mold cavity up to 100% of volume, and forming the solid part.
