Ana amfani da injinan samar da gilashi masu rufi don ƙera tagogi masu gilashi biyu ko uku tare da ingantattun kaddarorin rufi. Layin samarwa yawanci ya haɗa da injina don goge gefuna, wanke gilashi, cika iskar gas, da kuma rufe na'urorin gilashin. Tsarin ya haɗa da sanya wani Layer na iskar gas ko iska tsakanin gilashi biyu ko fiye, wanda ke taimakawa rage canja wurin zafi da watsa hayaniya. Wasu injina na yau da kullun da ake amfani da su wajen samar da gilashi masu rufi sun haɗa da injin rufe gilashi, injin rufe butyl, injin lanƙwasa sandar spacer, injin cika sieve na ƙwayoyin halitta, robots masu rufewa ta atomatik.

Injin Gilashin Rufe Gilashi: Wannan injin ya ƙunshi ɓangaren ɗaukar gilashi, ɓangaren wanke gilashi, ɓangaren duba tsaftar gilashi, ɓangaren haɗa spacer aluminum, ɓangaren matse gilashin, ɓangaren sauke gilashin, ɓangaren wanke gilashin da ake amfani da shi don tsaftacewa da busar da gilashin kafin a haɗa shi cikin na'urar gilashin da aka rufe. Injin wanke gilashin ya haɗa da goge-goge, bututun feshi, da wuƙaƙen iska don tsaftace saman gilashin da kuma cire duk wani ƙazanta.

Injin Lankwasa Sandunan Spacer: Sandar spacer muhimmin bangare ne na na'urar gilashin da ke raba gilashin kuma tana riƙe su a wurin. Ana amfani da injin lankwasa sandunan spacer don siffanta sandar spacer zuwa girman da siffar da ake buƙata bisa ga girman gilashin.

Injin Cika Sieve na Molecular Sieve: Ana amfani da sieve na molecular don shanye duk wani danshi da kuma hana hazo tsakanin bangarorin gilashin. Injin cikewa yana saka kayan sieve na molecular cikin hanyoyin sand ɗin spacer ta cikin ƙananan ramuka.

Robot Mai Rufewa ta Atomatik: Wannan injin yana amfani da marufin a tsakanin gilashin don samar da hatimin hermetic wanda ke hana iska ko danshi shiga sararin da ke tsakanin kwalayen. 

Waɗannan injunan suna aiki tare don ƙirƙirar na'urar gilashi mai ƙarfi wacce ke ba da ingantaccen kariya da kariya daga sauti.
