Iphinde yashicilelwa kwi-micro injection ekubumbeni
Ukukhutshwa kwesitofu sokungunda kuyingxaki ebalulekileyo kuyilo lokungunda, ngakumbi ekubumbeni isitofu esikhawulezileyo, iimfuno zokukhupha isitofu sokungunda zingqongqo ngakumbi.
(1) Umthombo wegesi kwi-injection mold.
1) Umoya kwi-gating system kunye ne-mold cavity.
2) Ezinye izinto eziluhlaza ziqulethe amanzi angazange asuswe ngokomiswa.Zigasified zibe ngumphunga wamanzi kwiqondo lokushisa eliphezulu.
3) Irhasi eveliswa ngokubola kwezinye iiplastiki ezingazinzanga ngenxa yobushushu obuphezulu ngexesha lokubunjwa kwenaliti.
4) Kutheni le nto kufuneka i-exhaust system isetelwe ukungunda kwenaliti yerhasi eyenziwe ngokuguquka okanye ukusabela kweekhemikhali ezihlangeneyo zezinye izongezo kwimathiriyeli ekrwada yeplastiki?Kutheni le nto kufuneka kumiselwe inkqubo yokukhupha isitofu.
(2) Iingozi zokuphelelwa ngamandla
Ukukhutshwa okulambathayo kwesitofu sokungunda kuya kuzisa uluhlu lweengozi kumgangatho wamalungu eplastiki kunye neminye imiba emininzi.Eyona midlalo iphambili yile ilandelayo:
1) Kwinkqubo yokubumba i-injection, i-melt iya kuthatha indawo yegesi kwindawo.Ukuba igesi ayikhutshwa ngexesha, kuya kwenza kube nzima ukuzalisa i-melt, kubangele umthamo onganeleyo we-injection kwaye awukwazi ukuzalisa i-cavity.
I-2) I-gas ene-drainage engafanelekanga iya kwenza uxinzelelo oluphezulu kwi-mold cavity kwaye ingene kwiplastiki phantsi kweqondo elithile loxinzelelo, okubangelwa iziphene ezisemgangathweni ezifana ne-pores, i-cavities, i-tissue ekhululekile, i-crazing njalo njalo.
3) Ngenxa yokuba igesi ixinzelelwe kakhulu, iqondo lokushisa kwi-mold cavity likhuphuka ngokukhawuleza, elikhokelela ekuqhekekeni kunye nokutshiswa kwe-melt ejikelezileyo, okubangelwa i-carbonization yendawo kunye nokutshalwa kweengxenye zeplastiki.Ibonakala ikakhulu ekudibaneni kwezinyibiliko ezimbini, * i-engile kunye neflange yesango.
I-4) Iimpawu zomatshini ngamnye we-melt cavity ziyahluka, okwenza kube nzima ukuba i-melt ingene kwi-mold kwaye ikhuphe uphawu lwe-weld.
I-5) Ngenxa yokuphazamiseka kwegesi kwi-cavity, kuya kunciphisa isantya sokuzalisa i-mold, kuchaphazela umjikelezo wokubumba kunye nokunciphisa ukusebenza kakuhle kwemveliso.
(3) Ukuhanjiswa kwamaqamza kwiindawo zeplastiki
Kukho imithombo emithathu ephambili yegesi kwi-cavity: umoya oqokelelwe kwi-cavity;Irhasi eveliswa ngokubola kwimathiriyeli ekrwada;Amanzi ashiyekileyo kunye nomphunga wamanzi owenziwe ngumphunga kwizinto eziluhlaza zineendawo ezahlukeneyo zamaqamza ngenxa yemithombo eyahlukeneyo.Kutheni le nto umngundo wokutofa kufuneka uxhotyiswe nge-exhaust system?Uyilo lokungunda.
I-1) Iibhubhu zomoya eziveliswa ngumoya oqokelelweyo kwi-mold cavity zihlala zisasazwa kwindawo echasene nesango.
2) Amaqamu enziwe ngokubola okanye ukusabela kweekhemikhali kwimathiriyeli ekrwada yeplastiki asasazwa kubunzima bamalungu eplastiki.
3) Amaqamza aveliswa ngamanzi ashiyekileyo egasification kwizixhobo zeplastiki asasazwa ngokungaqhelekanga kuyo yonke inxalenye yeplastiki.
Ukususela ekusasazeni amaqamza kumacandelo eplastiki angasentla, asikwazi ukugweba kuphela ubunjani bamaqamza, kodwa sigwebe nokuba i-exhaust part of mold ichanekile kwaye inokwethenjelwa.
