Yintoni ukubumba irabha?

Ukubumba irabha yinkqubo yokuvelisa esetyenziselwa ukuvelisa iimveliso zerabha ezibunjiweyo ngokubumba imathiriyeli yerabha ekrwada kwifomu efunwayo.Le nkqubo ibandakanya ukusebenzisa umngundo okanye umngxuma ukunika iimilo ezithile kunye neempawu kwirabha, okukhokelela kwimveliso yokugqibela eneempawu kunye neempawu ezifunwayo.Ukubumba irabha bubuchule obuguquguqukayo obusetyenziswa ngokubanzi kumashishini ahlukeneyo ukuvelisa amacandelo erabha anemisebenzi eyahlukeneyo.

Kukho iintlobo ezininzi zeenkqubo zokubumba irabha, nganye ifanelekile kwizicelo ezahlukeneyo kunye neemfuno zemveliso.Ezinye iintlobo eziqhelekileyo zokubumba irabha ziquka:

Ukubunjwa kwesitofu:

Xa kusenziwa isitofu, imathiriyeli yerabha ekrwada iyafudunyezwa ide inyibilike ize emva koko itofwe kumngxuma wokungunda phantsi koxinzelelo oluphezulu.I-rubber iqina kwi-mold, ithatha isimo sayo.Le nkqubo isebenzayo kwimveliso ephezulu yeerubha eziyinkimbinkimbi kunye nezichanekileyo.

Ukubunjwa koxinzelelo:

Ukubumba ukunyanzeliswa kubandakanya ukubeka isixa esilinganisiweyo kwangaphambili semathiriyeli yerabha ngokuthe ngqo kumgodi wokungunda ovulekileyo.Umngundo uyavalwa, kwaye uxinzelelo lufakwa ukucinezela irabha, ibangela ukuba ithathe ubume bobumba.Ukubunjwa koxinzelelo kukulungele ukuvelisa uluhlu olubanzi lweemveliso zerabha ezinobunzima obuhlukeneyo.

Ukutshintshela ukubunjwa:

Ukubunjwa kokutshintshela kudibanisa izinto zokubumba inaliti kunye nokubunjwa koxinzelelo.Izinto zerabha zifudunyezwa ngaphambili kwaye zilayishwe kwigumbi, kwaye emva koko i-plunger inyanzela loo nto kwi-mold cavity.Le ndlela ikhethwa kwiimveliso ezifuna ukuchaneka kunye neenkcukacha eziyinkimbinkimbi.

Ukubunjwa kwesitofu solwelo (LIM):

Ukubunjwa kwesitofu solwelo kubandakanya ukutofa irabha elulwelo ye-silicone kumgodi wokungunda.Le nkqubo ifaneleke ngokukodwa ukuvelisa amacandelo erabha aguquguqukayo kunye neyinkimbinkimbi, edla ngokusetyenziswa kwizixhobo zonyango kunye nezinye izicelo apho ukuchaneka okuphezulu kubalulekile.

Ukubumba ngaphezulu:

Ukubumba ngaphezulu kubandakanya ukufakwa komaleko werabha kwi-substrate ekhoyo okanye icandelo.Oku ngokuqhelekileyo kusetyenziselwa ukongeza umgangatho othambileyo okanye obambekayo kwinto eqinileyo, ephucula ukubambelela kwayo, ukuqina, okanye ukutsala umdla wobuhle.

Ukukhethwa kwenkqubo yokubumba irabha kuxhomekeke kwizinto ezifana nobunzima benxalenye, umthamo ofunekayo, iipropati zezinto eziphathekayo, kunye nokuqwalaselwa kweendleko.Ukubumba irabha kusetyenziswa ngokubanzi kwimizi-mveliso yeemoto, i-aerospace, i-elektroniki, yezonyango, kunye nempahla yabathengi ukwenza uluhlu lweemveliso ezahlukeneyo, kubandakanya itywina, iigaskets, ii-O-ring, amatayara, kunye nezinye izinto ezahlukeneyo zerabha.
