Uxinzelelo oluphantsi kunye oluphakathiumbhobho webhoyilaisebenzisa i-ingot yentsimbi okanye ityhubhu eqinileyo kwi-capillary enemingxuma, kwaye emva koko ucofe olwenziwa yi-hot-rolled, ebandayo okanye ebandayo.
Ngokwezibalo ezingaphelelanga, amashishini imveliso imibhobho China ingenamthungo malunga 240 ngaphezu iyunithi umbhobho intsimbi engenamthungo imalunga ngaphezu 250 iiseti umthamo wemveliso malunga 450 yezigidi zeetoni.Kubonwa kwi-caliber <φ76, i-akhawunti ye-35% <φ159-650, i-akhawunti ye-25%.Ukusuka kwiintlobo ngeentlobo zenjongo jikelele ye-1.9 yezigidi zeetoni, ezithatha i-54%;umbhobho we-oyile iitoni ezingama-760,000, ezibalelwa kwi-5.7%;ipropu ye-hydraulic, i-tube echanekileyo i-15 yezigidi zeetoni, i-akhawunti ye-4.3%;umbhobho wensimbi engenasici, iibhobho, iityhubhu yeemoto ezipheleleyo zeetoni ezingama-50 000, ezibalelwa kwi-1.4%.

Umbhobho webhoyila woxinzelelo oluphantsi noluphakathi Umgangatho: I-GB3087-1999 ibhoyila yoxinzelelo oluphantsi kunye noxinzelelo oluphakathi kwiityhubhu zentsimbi ezingenamthungo.

Umbhobho webhoyila woxinzelelo oluphantsi nophakathi usetyenziselwa ukwenza iintlobo ngeentlobo zezakhiwo ezinebhoyila yoxinzelelo oluphantsi imibhobho yerola yomphunga oshushu kakhulu kunye nombhobho webhoyila oshushu kakhulu, umbhobho we-opium, umbhobho omncinci kunye ne-arch imisebenzi yezitena zomgangatho ophezulu wekhabhoni yolwakhiwo lwentsimbi eshushu-isolwe kwaye ibandayo. (iqengqiwe) ityhubhu engenamthungo.Isetyenziswa ikakhulu kwiibhoyila zoshishino kunye nebhoyila ekuhambiseni ulwelo oluphantsi loxinzelelo kumbhobho.Ummeli wezinto eziphathekayo 10, i-20 yentsimbi.
