Iindlela ezikhethekileyo zokubumba inaliti yeplastiki zichazwe ukususela kwesi sifundo. Okokuqala, kwesi sifundo sichaza indlela yokubumba inaliti yombala emibini.
Indlela yokubumba inaliti yombala emibini yindlela yokubumba esandula ukubizwa ngokuba "yindlela yokubumba inaliti yezinto ezimbini" okanye "indlela yokubumba yesitofu sezinto ezahlukeneyo", njl njl. Iintlobo ezimbini zeresin ye-thermoplastic zitofwa ngokulandelelanayo kubumba ngokwahlukeneyo ngokwahlukeneyo. iisilinda zokutofa, ngaloo ndlela zivelisa imveliso eneentlobo ezimbini zemibala.
Le yitekhnoloji yokubumba esetyenziswa ngokubanzi ekulungiseleleni izitshixo eziphambili zeePC zedesktop eziphezulu, okanye amaqhosha akhanyayo eeyunithi zokuhamba ngemoto, njl.
Ngokubanzi, kubonakala ngathi kusetyenziswa i-resin ezimbini zeplastiki zohlobo olufanayo njengeplastiki ye-PS okanye iplastiki ye-ABS. Oku kungenxa yokuba kukho ukunamathela okuhle kakhulu phakathi kwezinto ezimbini ezibunjiweyo. Nangona kunokwenzeka ukuvelisa iimveliso ezibunjiweyo ezivela kwiintlobo ezimbini zeplastiki ze-resin ezifana ne-ABS kunye ne-POM, ukunamathela phakathi kwabo akulunganga. (Kukho izicelo ezahlukeneyo xa i-adhesion ilungile kwaye xa i-adhesion ingalungile.)
Ukongeza, kutsha nje kukho indibaniselwano ekhethekileyo esele ifunyenwe njengendibaniselwano yemathiriyeli yeplastiki ye-thermoplastic kunye ne-elastomer ye-thermoplastic (i-resin yeplastiki efana nerabha). (Impahla yezemidlalo, njl.)
Ukuze usebenzise indlela yokubumba inaliti yombala emibini, ngokwesiqhelo, umatshini wokubumba okhethekileyo uya kufuneka. Oomatshini abanjalo benziwa ngabavelisi boomatshini bokubumba iinaliti eJapan nakumazwe afana neSwitzerland neJamani. Umatshini wokubumba wokubumba uxhotyiswe ngeeyunithi ezimbini zokutofa, ezithi ngokulandelelana zigalele izinto ezityhidiweyo ngaphakathi komngxuma wokungunda ngokusebenzisa i-sprues yazo.
Kwi-mold, inxalenye yowesifazane we-cavity yenziwa kwicala elisisigxina lezinto zeplastiki ezifanelekileyo.
Ngakolunye uhlangothi, ii-cores ezimbini zesilisa zesimo esifanayo zenziwe kwisiqingatha esihambayo, kwaye isithuba phakathi kwamalungu endoda sinokushukunyiswa yindlela ejikelezayo okanye i-sliding mechanism. (Kukho iindidi ezininzi zeepateni zesi sakhiwo.)
Kwindlela yokubunjwa kwenaliti yombala emibini, kuba imveliso entle eyenziwe ngezinto ezininzi inokuveliswa kwinqanaba elinye, kunokwenzeka ukuvelisa into ebunjiweyo kunye nokongezwa kwexabiso eliphezulu. Kwakhona kunokwenzeka ukuba ube nemiqolomba emininzi kwisitofu esinye kwimeko yezinto ezibunjiweyo ezinobungakanani obuncinci.
Nangona kunjalo, ukuyila kwee-molds kufuna ulwazi malunga nokuyila ubuninzi beendonga kunye nokwazi malunga nokudibanisa phakathi kwezinto ezahlukeneyo zeplastiki. Ezinye iindlela zobuchule ziya kuba yimfuneko malunga nolawulo lobushushu lokungunda.
