Popeza anthu alowa m'gulu la mafakitale, kupanga zinthu zamitundu yonse kwachotsa ntchito zamanja, kupanga makina opangira makina kwakhala kotchuka m'mitundu yonse ya moyo, ndipo kupanga zinthu zapulasitiki ndizosiyana, masiku ano, zinthu zapulasitiki zimakonzedwa ndi makina omangira jekeseni, monga zipolopolo za zida zosiyanasiyana zapanyumba ndi zinthu za digito zomwe ndizofala m'moyo wathu watsiku ndi tsiku zimakonzedwa ndijekeseni akamaumba. Kodi pulasitiki yathunthu imakonzedwa bwanji mu makina opangira jakisoni?
1. Kutentha ndi preplasticization
The wononga imayendetsedwa ndi galimoto dongosolo, zinthu kuchokera hopper patsogolo, akaumbike, mu yamphamvu kunja chotenthetsera, wononga ndi mbiya kukameta ubweya, mikangano pansi pa kusanganikirana zotsatira, zinthu pang'onopang'ono kusungunuka, mu mutu wa mbiya wasonkhanitsa kuchuluka kwa pulasitiki wosungunuka, pansi pa kupanikizika kwa Sungunulani, wononga pang'onopang'ono kumbuyo. Mtunda wobwerera kumadalira kuchuluka kwa jekeseni imodzi ndi chipangizo cha metering kuti chiwongolere, pamene voliyumu ya jekeseni yokonzedweratu ikafikira, phula imasiya kuzungulira ndikubwerera.
2. Kumanga ndi kutseka
Makina omangirira amakankhira mbale ya nkhungu ndi gawo losunthika la nkhungu lomwe limayikidwa pa mbale yosunthika kuti itseke ndi kutseka nkhunguyo ndi gawo losunthika la nkhunguyo pa mbale yosunthika kuti zitsimikizire kuti mphamvu yotchinga yokwanira ingaperekedwe kutseka nkhunguyo pomanga.
3. Patsogolo kayendedwe ka jekeseni
Kutseka kwa nkhungu kumalizidwa, mpando wonse wa jekeseni umakankhidwa ndikusunthira patsogolo kuti jekeseni ya jekeseni igwirizane ndi kutsegula kwa sprue kwa nkhungu.
4.Injection ndi kukakamiza-kugwira
Pambuyo pobowoleza nkhungu ndi mphuno kuti zigwirizane ndi nkhunguyo, silinda ya hydraulic imalowa m'mafuta othamanga kwambiri ndikukankhira kutsogolo kwa mbiya kuti isungunuke yomwe imasungunuka m'mutu wa mbiyayo ndikukakamiza kokwanira, zomwe zimapangitsa kuti voliyumu ya pulasitiki ikhale yochepa chifukwa cha kuchepa kwa kutentha. Kuonetsetsa kuti makulidwe, dimensional molondola ndi mawotchi katundu wa pulasitiki mbali, m'pofunika kukhalabe ena kupsyinjika pa kusungunula mu nkhungu patsekeke kudzaza zinthuzo.
5. Kutsitsa kuthamanga
Pamene kusungunula pachipata cha nkhungu kuzizira, kupanikizika kungathe kutulutsidwa.
6. jekeseni chipangizo kumbuyo
Nthawi zambiri, kutsitsa kukamalizidwa, zomangira zimatha kuzungulira ndikubwerera kuti mumalize kudzaza kotsatira ndi preplasticization.
7. Tsegulani nkhungu ndikuchotsani mbali zapulasitiki
Zigawo za pulasitiki mu nkhungu zitazizidwa ndikuyikidwa, makina omangira amatsegula nkhungu ndikukankhira mbali zapulasitiki mu nkhungu.
Kuyambira pamenepo, wathunthu pulasitiki mankhwala amaonedwa wathunthu, ndithudi, mbali zambiri za pulasitiki adzafunika kutsatiridwa ndi kupopera mafuta, silika-screening, kutentha masitampu, laser chosema ndi njira zina wothandiza, ndiyeno anasonkhana ndi mankhwala ena, ndipo potsiriza kupanga mankhwala wathunthu pamaso chomaliza m'manja mwa ogula.
