摘要: This report was carried out to study experimentally the water-assisted injection molding process of glass fiber-reinforced polyamide-6 (Nylon-6) composites. Experiments were on an 80 ton machine equipped with a lab scale water system, which included pump, pin, pressure accumulator, tank temperature regulator, and control circuit. The materials used Nylon 30% fiber-filled A spiral mold cavity After molding, lengths penetration in molded parts measured. effects different processing parameters determined: melt temperature, melt-filling speed, short-shot size, pressure, hold, delay time. Mechanical property tests performed parts. X-ray diffraction also employed identify structural materials. In addition, in-mold distribution polymeric during cooling Irregular observed, found affect crystallinity Nevertheless, its tensile properties relatively limited.
