Ubugcisa neSayensi yeeMbumba zePlastiki zeCosmetic
Kwihlabathi lanamhlanje, i-aisle yobuhle yindlela yokupakisha. Phakathi kweendlela eziqhelekileyo kukho ityhubhu ethambileyo yeplastiki, esetyenziselwa yonke into ukusuka kwi-toothpaste ukuya kwi-cream yesandla. Nangona abathengi beyixabisa indlela eyilwe ngayo, bambalwa abaqondayo ukuba ubukho betyhubhu buxhomekeke kwisixhobo esenziwe ngobuchule: i-mold. Ukudalwa kwezi fom yinkqubo enzima apho ubunjineli obuchanekileyo budibana nesayensi yezinto eziphathekayo.
Uhambo luqala kwisigaba esicokisekileyo sokwenza isikhunta. Njengoko kuchaziwe kwinkqubo ephambili, inyathelo lokuqala kukuguqulela iingcamango zibe sisixhobo esibonakalayo. "Yenza isikhunta ngokwemizobo yoyilo, ngokuqhelekileyo usebenzisa ubuchwepheshe obufana noomatshini be-CNC kunye nokushicilela kwe-3D." Umatshini wokulawula amanani ekhompyutha (CNC) ngumsebenzi onzima kweli nqanaba, kusetyenziswa izixhobo ezikhokelwa yikhompyutha ukukrola imingxuma kwiibhloko zesinyithi ngokuchanekileyo kwinqanaba le-micron. Ezi mingxuma ziyi-negative yetyhubhu; xa iplastiki ifakwa, zenza imo yokugqibela. Kwijometri ezintsonkothileyo, ukuprinta kwe-3D kusetyenziswa ngakumbi, okuvumela ukuphindaphinda koyilo ngokukhawuleza kunye nokuthungwa okuntsonkothileyo okulinganisa izinto ezifana nesikhumba—okunqweneleka kakhulu kushishino lwezithambiso.
Okubaluleke ngokufanayo kukukhethwa ngononophelo kwezinto ezikwimold. Isicatshulwa esiphambili sithi "Izinto ezikwimold zingakhethwa kwiglasi, iplastiki, uqalo, umthi, njl.njl., kwaye ukhetho oluthile lumiselwa ngokweemfuno zemveliso." Ekuqaleni, olu luhlu lunokubonakala lumangalisa, njengoko igama elithi "imold" lidla ngokukhumbuza imifanekiso yentsimbi enzima. Enyanisweni, ukhetho sisigqibo esicwangcisiweyo esisekelwe kubukhulu kunye nenjongo. Kwimveliso enkulu, apho kufuneka izigidi zeetyhubhu, iimold zihlala zenziwe ngentsimbi eqinileyo ukuze zimelane noxinzelelo olukhulu. Nangona kunjalo, kwimveliso yexesha elifutshane okanye iprototyping, izinto ezifana ne-aluminium okanye iiplastiki ezikhethekileyo ziyasebenziseka. Ukukhankanywa "kwe-bamboo" kunye "nomthi" kunomdla ngokukodwa; ezi zisetyenziswa phantse kuphela ekupakisheni okwenziwe ngesandla okanye kobugcisa, apho imold ngokwayo inokuba yimo eqingqiweyo yokwenza iiplastiki zebhayoloji, okanye ekwenzeni imodeli yokuqala eyiyo. "Iimfuno zemveliso" - ubungakanani, uhlahlo lwabiwo-mali, kunye nokugqitywa okufunekayo - zichaza ukuba imold yenziwe ngentsimbi ehlala ixesha elide kangangeminyaka elishumi yenkonzo okanye imo yomthi elula kwimveliso yohlobo olulinganiselweyo.
Ukuqukumbela, ityhubhu yokuhombisa ethobekileyo ingqina intsimi enobuchule yokwenza isikhunta. Yindlela apho ukuchaneka kwe-CNC machining kunye nokuguquguquka kokuprinta kwe-3D kuzisa uyilo ebomini, kwaye apho ukukhetha izinto kubonisa ukuqonda okunzulu koqoqosho lwemveliso. Kunokuba kube lula, ityhubhu yimveliso ezelwe sisixhobo sobunjineli esintsonkothileyo nesiqwalaselwe ngononophelo: isikhunta.
