Plastic jekiseni processing
Ndeapi makuru majekiseni maitiro paramita epurasitiki jekiseni processing tekinoroji?Kuyerera kwezvinhu.Shanduko mukuita kwekunyunguduka kuyerera / shrinkage / kuomesa.Tenzi panguva ino anofanira kunge ane maonero kuitira kuti aone kuburikidza nekuchinja kwezvinhu zvinonyunguduka mumushini / mold.Sei?Kushushikana kuchaitika kupi mushure mekuderera?Nzira yekuendesa sei kupisa?Neiko kune dzvinyiriro yomukati?Chii chichaitika?Kugona uku ndiko kune nzvimbo iyi yakakwirira kupfuura yekare.Kana nzvimbo yechitatu ichionekwa ine zviratidzo zvishoma pane zviratidzo zvakawanda kubva kunze kusvika mukati, nzvimbo kubva mukati kusvika kunze, umo kukanganisa kunopindirana nemufananidzo wehove hachirevi chinhu, uye zviyero zvinova nyore kwazvo.Paunenge uchigadzira molds epurasitiki, yakawandisa kumashure kudzvinyirira kunogona kukonzera anotevera matambudziko:
Kunyunguduka kumberi kwembiya kwakakwira zvakanyanya, tembiricha yemidziyo yakakwira, viscosity inodzikira, iyo yakanyungudutswa inoyerera ichidzokera muscrew groove, kuyerera kwemvura kuyerera pakati pembiya uye screw gap kunowedzera, uye kuita kweplasticizing. (huwandu hwezvinhu zvinogona kuve zvepurasitiki pane imwe nguva yeyuniti) inoderera.
Kune mapurasitiki ane yakaderera thermal kugadzikana (senge PVC, POM, etc.) kana colorants, tembiricha yekunyunguduka inowedzera uye nguva yekupisa yedhiramu inowedzera, zvichikonzera kuwedzera kwekuora kwekupisa kana ruvara rwemavara, uye kudzikira kweruvara / kupenya kwe. chigadzirwa pamusoro.
Iyo yekumashure dzvinyiriro yakakwira zvakanyanya, screw inodzokera, iyo pre epurasitiki yekuchaja nguva yakareba, nguva yekutenderera inowedzera, uye chibereko chinodzikira.
Plastic mold processing
Iyo yekumashure kumanikidzwa kwakakwira uye kudzvanywa kwezvinhu zvakanyungudutswa kwakakwira.Iyo muromo inowanzoita kunyunguduka drool mushure mejekiseni.Kana chinonamira chaiswa jekiseni rinotevera, zvinhu zvinotonhora mugero remuromo zvinoonekwa zvinotonhora zvezvinhu pamuromo kana chigadzirwa.
Mukuita kwepurasitiki yedoro, kumanikidzwa kwemashure kwakakurisa, muromo unodonha, unorasa zvigadzirwa, uye mhete yekudziya padyo neinopinza inopisa zvakanyanya.
Paunenge uchigadzira molds epurasitiki, yakawandisa kumashure kudzvanywa kuchawedzera kupfeka kwemakanika kwepre plastic mechanism uye screw barrel.
