Ubusika buza ngokungazi, kwaye kulindeleke ukuba siqalise ukufudumeza kule nyanga. Kwangaxeshanye, intsimbi yokusila iye yafumana nesaziso sokusingqongileyo, kwaye nakuphi na ukusetyenzwa, njl., kufuneka inqunyanyiswe, njengale: umzobo wombhobho wentsimbi ongenamthungo, i-beveling yentsimbi engenamthungo, ukwandiswa kwemibhobho yentsimbi engenamthungo, njl. njl. umbhobho wentsimbi ongenamthungo wokugquma umbhobho, ukuqhunyiswa kwesanti yombhobho wentsimbi engenamthungo, umbhobho wentsimbi ongenamthungo wokugalela, ukucholwa kombhobho wentsimbi engenamthungo, njl. njl., ekufuneka imiselwe ngokweemfuno ezithile umthengi. Ukuba ungxamele ukusebenzisa nokufumana iimpahla kungekudala, nceda waziswe kwaye ulungiselele kwaye uphendule kwangaphambili.
intshayelelo esisiseko:

Umbhobho wentsimbi ongenamthungosisicangca eside sentsimbi esinecandelo elimgongxo kwaye akukho mithungo siyijikelezileyo. Yenziwe ngee-ingots zentsimbi okanye izikhala zetyhubhu eziqinileyo ngokugqobhoza emva koko zishushu-zisolwe, ziqengqeleke ngokubanda okanye zitsalwe ngokubanda.

Imibhobho yentsimbi engenamthungo isebenzisa:

Ukusetyenziswa kwemibhobho yentsimbi engenamthungo ikakhulu kubonisa iindawo ezintathu ezinkulu. Enye yintsimi yokwakha, enokusetyenziswa ngaphantsi komhlabaumbhobhouthutho, kubandakanywa nokutsalwa kwamanzi aphantsi komhlaba xa kusakhiwa izakhiwo. Okwesibini yintsimi yokucubungula, enokusetyenziswa kuyoukusetyenzwa koomatshini, ukuthwala imikhono, njl. Okwesithathu yintsimi yombane, kuqukaimibhobhoukuhanjiswa kwerhasi, imibhobho yolwelo yokuvelisa umbane wamanzi, njl.

Umzekelo, imibhobho yentsimbi engenamthungo isetyenziswa kwizakhiwo, ukuthuthwa kwamanzi,iibhoyila zoxinzelelo oluphantsi naphakathi, iibhoyila zoxinzelelo oluphezulu, izixhobo zesichumiso, ukuqhekeka kwepetroleum, ukomba ngokwejoloji, ukomba wedayimani ongundoqo,ukomba ioli, iinqanawa, i-automobile half-shaft casings, ii-injini ze-diesel, njl. Ukusetyenziswa kwemibhobho yensimbi engenamthungo kunokuphepha iingxaki ezinjengokuvuza, ukuqinisekisa ukusetyenziswa kokusetyenziswa, kunye nokuphucula ukusetyenziswa kwezinto eziphathekayo.
