Idayamitha yangaphandle yombhobho ongenamthungo oqengqelekayo ngokuqhelekileyo mkhulu kune-32mm, kwaye ubukhulu bodonga yi-2.5-200mm. Ububanzi obungaphandle bombhobho wentsimbi ongenamthungo obandayo bunokufikelela kwi-6mm, kwaye ubukhulu bodonga bunokufikelela kwi-0.25mm. Idayamitha yangaphandle yombhobho obhityileyo unokufikelela kwi-5mm kwaye ubukhulu bodonga bungaphantsi kwe-0.25mm.

Umbhobho wentsimbi esetyenziswa ngokubanzi ingenamthungo yenziwe nge-10, 20, 30, 35, 45 kunye nezinye ezikumgangatho ophezulu we-carbon bonded steel 16Mn, 5MnV kunye nezinye intsimbi ephantsi yolwakhiwo lwentsimbi okanye i-40Cr, 30CrMnSi, 45Mn2, 40MnB kunye nezinye intsimbi edibeneyo ebandayo yaqengqeleka.10, 20 kunye nezinye carbon steel ephantsi imveliso umbhobho ingenamthungo isetyenziselwa ikakhulu umbhobho fluid.45, 40Cr kunye nezinye medium carbon steel eyenziwe ngombhobho ingenamthungo ukuvelisa iindawo oomatshini, ezifana iimoto, iitrektara wagxininisa iindawo.Ukusetyenziswa jikelele ingenamthungo umbhobho wentsimbi ukuqinisekisa ukomelela kunye novavanyo oluthe tyaba.Imibhobho yentsimbi egotyiweyo eshushu ihanjiswa kwindawo eshushu yaqengqwa okanye iphathwa ngobushushu.
