More Information
Summary:The invention relates to the production of sedan car instrument panel plastic part production using air assisted micro hole foaming injection, comprising a forming parameter optimization, marginal fluid or polymer smelt single solution mold flow, instrument panel physical analog mold design, pouring system optimization design, dimension parameter selection. Through optimizing the mold and its pouring system, preset process parameter, it controls the air smelt forming inside the charging barrel, to achieve instant foam, growing, fixing, forming micro foam dimensional hole radius, with excellent appearance quality, without dent, warping and improved in instrument panel mechanical feature.
