Shanghai Daoqin Plastics Co., Ltd.

一． 目: most fast speed degree, most low cost, most molding cycle to product quality requirements. 二． suitable scope/range: suitable for injection molding parts 部调 machine 人员 调 machine and production process adjustment as 业. 三． as process/workflow: 四． as control: 1． as 业准备: a． 无论 is new product also is already production product, must tool necessary production process material, product sheet/plate, material property can material and its product weight, injection molding parts mold structure material. already production product, production process material, electrical and will tool, equipment adjustment to 规定状态. b． 检查 equipment, injection molding parts mold, material is can 进入调 machine 状态, material is dry, injection molding parts mold is 否清理 dry can positive as, material is 否清洗 dry 净; material temperature degree is to molding temperature degree, water is 否打开 and other. 2．调 machine: is already production product, process parameters rear as positive 常, product 经QC检验OK rear can amount production. is new product: a． setting material temperature degree is positive molding temperature degree. according to product weight, setting and 射胶行程; b． according to injection molding parts mold process/workflow 确定射胶 pressure speed degree, generally in pressure （50-80）, speed degree （30-60）; c． according to gate type type, large small setting holding pressure time, （点 gate 6-8S, gate and gate 先8-10S）; d． according to injection molding parts mold cooling water distribution and product thick cooling time, setting is 15-20秒; e． 然 rear 进行手动啤货, according to defect specific increase or decrease/reduce has data, 直至达 to product quality requirements also can positive production; f.由手动变 is semi 自动, production 边调校 data, most injection molding parts cycle. molding cycle =开锁模 time + injection time +熔胶 time + cooling time, for above 4 time amount shrink short. generally 一台4安士 injection molding parts machine, is sheet/plate injection molding parts mold, mold opening or time separation control in 2秒 left right, has can 适当调 slow. injection time adjustment 按0.5秒递 decrease 试啤, 直至出现 defect, 停止调校 again to upper data. time 确定尽 amount decrease/reduce back pressure and add fast speed degree, 以不出现 mixed color, is 宜. cooling time adjustment 同射胶 time adjustment, 以1秒 is decrease time 试啤, will formed product and standards sheet/plate comparison, 若两者 quality same, is most 佳调校 time.
