Shanghai Daoqin Plastics Co., Ltd.

近期, certain plastics products enterprise export Japan 一批价 value 4200美元 plastics box/case cover/cap method 开启自如, can meet/satisfy demand to 退运处理.

宁波宁海检验检疫局即刻派员进行退货调查. 经调查发现, 该批pp plastics box/case cover/cap in warpage deformation, inner combined rear method 开启. 进一步 in-depth understanding rear 获知, due to enterprise 实行计 parts tube/pipe 理, is speed degree adjustment injection molding machine process parameters, will cooling time 由7秒 decline is 5秒, make pp cover/cap warpage deformation, 直接导致客户 function demand method achieve.

据 understanding, injection molding product warpage deformation effect/influence factors relatively more, remove plastics raw materials property can outer, most main/primary factors is injection molding machine process parameters setting, its in holding pressure pressure, melt temperature degree, injection time and cooling time and other different degree effect/influence injection molding parts molding.

is 此, related enterprise, is 严格树立 quality 立企意识, enterprise is product quality responsibility 人, add strong/high training. is setting production process, production front according to product structure, material separation made as injection molding process table/sheet, combined mold trial parts ensure process parameters 适宜充 separation. is production process quality tube/pipe 控, for injection molding and other key/critical control add strong/high process parameters and product features and amount, 杜绝因 process defect, as and other causes formed product warpage deformation quality issues.
