Le nkomishi yengilazi ye-borosilicate ephezulu enezimbobo yakhiwe ngefilosofi "yezinto ezibonakalayo njengesisekelo, ubuciko njengomphefumulo," ihlanganisa kahle izici ezinzile zengilazi ephezulu ye-borosilicate nokukhiqizwa okunembayo. Ukusuka ekukhethweni kwezinto ezingavuthiwe kuya ekulethweni komkhiqizo oqediwe, kuba nezinqubo ezinzima. Inkomishi yengilazi ye-borosilicate ephezulu enezimbobo isebenzisa ingilazi ephezulu ye-borosilicate enokuqukethwe kwe-silica ephezulu, okuholela ekwakhekeni kwamangqamuzana enethiwekhi okuqinile okuvimbela ngokuyisisekelo ukucwiliswa kwezinsimbi ezisindayo. Ukuqinisekisa ubumsulwa bezinto ezibonakalayo, okuluhlaza kungena izinqubo ezintathu zokuhlanza ngaphambi kokungena esithandweni: isinyathelo sokuqala ukuhlukaniswa kazibuthe ukuze kukhishwe izinhlayiya zensimbi ezinosayizi we-micron{3}}; Isinyathelo sesibili ukugeza nokuhlola amanzi ukuze kukhishwe uthuli nokungcola; futhi isinyathelo sesithathu ukuhlukaniswa komoya ukuze kuqinisekiswe ukufana kwezinhlayiyana. Izinto ezingavuthiwe ezihlanziwe zibe sezifakwa esithandweni ukuze zincibilike. Phakathi nale nqubo, ubuchwepheshe be-vacuum degassing busetshenziselwa ukususa ngokuphelele amabhamuza omoya engilazini, ukuqinisekisa ukuthi inkomishi yengilazi eqediwe ayinawo amaphuzu ekristalu namabhamuza.
Izakhiwo eziphakeme zengilazi ephezulu ye-borosilicate zisetshenziswa ngokugcwele kule nkomishi yengilazi ye-borosilicate enezimbobo. Ingilazi ephezulu ye-borosilicate ine-coefficient yokunwetshwa kokushisa okuyingxenye eyodwa-kungxenye yesithathu kuphela yesoda evamile-ingilazi ye-lime, okusho ukuthi ingakwazi ukumelana nomehluko omkhulu wezinga lokushisa. Ukumelana kwayo nezinga lokushisa okungokwemvelo kuyivumela ukuba ibambe iziphuzo emazingeni okushisa ahlukahlukene, okuyenza ifaneleke kuzo zonke izinkathi zonyaka ngaphandle kokudinga ukushintshwa. Ngaphezu kwalokho, umzimba wendebe uthola ukwelashwa okuqiniswa ngokomzimba, wenza isendlalelo sokucindezeleka esicindezelayo ebusweni, sithuthukise ukumelana nomthelela. Ekusetshenzisweni kwansuku zonke, akuvamile ukuphuka ngisho namaconsi ngengozi, ukuxazulula inkinga yezinkomishi zeglasi ezijwayelekile eziphuka kalula.
Inkomishi yengilazi ephezulu ye-borosilicate enesivalo isebenzisa inqubo "ye-centrifugal casting + isandla-yokubumba". Ukujiya kodonga kwanqunywa ngokuhlolwa okuningiliziwe, okuqinisekisa kokubili ukwahlukanisa ukushisa okuhle kakhulu nomuzwa oqinile lapho ubanjiwe. Ngisho nangaphandle komkhono, kukhululekile ukubamba uma kugcwaliswe iziphuzo ezishisayo. Unqenqema lwenkomishi lwakhiwe ngobunyoninco, kuqala lugaywe ngamakhaza ukuze kukhishwe ama-burrs, bese lupholishwa ngelangabi{5}lokushisa eliphansi. Ngemva kwalezi zinqubo, i-rim ifinyelela ijika elibushelelezi neliyindilinga. Isisekelo sinomklamo ongasheleli{8}onomphetho oyisithwathwa, othuthukisa ukuzinza, ukuvikela ukuthepha, kanye nokuvikela amathebula amathebulethi angaklwebheki.
Isivalo esifanayo naso singesezinga eliphezulu, senziwe{{0}ngokudla kwe-silicone yebanga kanye nezinto eziyinhlanganisela ye-PP. Iringithoni yokuvala i-silicone ibunjwe ngomjovo ngokuphelele, ilingana kahle nomphetho futhi ivimbela ukuvuza ngisho noma ihlanekezelwa futhi inyakaziswa. Kuphephile ukuthwala esikhwameni sakho ngaphandle kokukhathazeka. Inkinobho ye-PP snap engaphezulu kwesivalo ibushelelezi futhi ayimi uma icindezelwa, ivumela ukuthi kube lula-ukuvula ngesandla esisodwa futhi ivimbele ngempumelelo uthuli nokugcina iziphuzo zishisa.
Phakathi naleso sikhathi, enye inzuzo enkulu yale nkomishi yengilazi ye-borosilicate ephezulu enesivalo kulula ukuyihlanza. Indawo ebushelelezi neminyene yengilazi ephezulu ye-borosilicate yenza kube nzima ukuthi amabala ekhofi nawetiye ahlale; ukugeza okulula ngamanzi yikho konke okudingekayo ukuze kubukeke kusha. Ngisho nangemva kokubamba itiye eliqinile isikhathi eside, ngeke kube khona okusalayo. Ukuze uthole amabala anenkani, ukumane ukucwiliswe ngenani elincane likaviniga omhlophe kuzowasusa kalula. Futhi iwumshini wokuwasha izitsha ophephile, okongela isikhathi nomzamo. Umzimba obonisa ngale ikuvumela ukuthi ubone kalula ukuthi uhlanzwa kanjani, ugweme noma yiziphi{5}}ukufinyelela{6}}ezindaweni okunzima ukufinyelela kuzo ukuthi zingangcoli.
