Igikorwa cyo kurunga hejuru ya - ubushyuhe bwa silicone reberi muri rusange igabanijwemo ibyiciro bibiri, aribyo - icyiciro kimwe na bibiri -.
Imwe - icyiciro cya volcanisation, kizwi kandi nko gushiraho ibirunga, gifite uburyo bwacyo bwo kurunga, ubushyuhe nigihe cyagenwe nuburyo bwo kubumba bwakoreshejwe, ubwoko bwa reberi hamwe nubunini bwibicuruzwa byanduye. Ibicuruzwa bibumbabumbwe bikorerwa muri mashini iringaniye, hamwe nubushyuhe bwikirunga hamwe na dogere selisiyusi 150 kugeza 180 hamwe niminota 10 kugeza 30. Rubber ya silicone ikora ibicuruzwa, kalendari, gufunga no guteranya bishobora guterwa ikirunga hifashishijwe imiyoboro y’ibirunga cyangwa ibigega bya volcanizing, hamwe nubushyuhe bwumuyaga hamwe nubushyuhe bwo gushyushya ibirunga, ni ukuvuga kubumba no guhuza bikorwa bikorwa ukwe.
Secondary vulcanisation, izwi kandi nka post - volcanisation, igamije kuvanaho ibintu bihindagurika cyangwa byangiza ibintu bihindagurika bisigaye mu bicuruzwa, kunoza umusaraba -, no guhuza imiterere yumubiri nubukanishi bwa reberi yibirunga. Ibikoresho bya rubber bya silicone nyuma yibiri - icyiciro cya volcanisation gifite compression nziza cyane, imiterere ya dielectric hamwe nibintu bihamye byumubiri nubukanishi. Icyiciro cya kabiri - icyiciro cya volcanisation gikorerwa muri convection ku gahato hejuru - ubushyuhe buri gihe agasanduku k'ubushyuhe ku bushyuhe bwa dogere 180 kugeza 200 mu masaha 2 kugeza 8.
Ibikoresho bya silicone birashobora gukorwa mubicuruzwa bitandukanye bibumbabumbwe (nk'amabati atandukanye ya reberi, gasketi, koza, n'ibindi), ibicuruzwa byakuwe hanze (nk'ibikoresho bitandukanye bya reberi, imigozi ya reberi, imirongo ya reberi, ibyuma by'insinga, n'ibindi), hamwe n'ibikoresho by'imyenda ya reberi (nk'imyenda yo kwifata -, imyenda yo kwigunga, n'ibindi) ukoresheje uburyo butandukanye bwo kubumba.
