HFD DHD munsi yumwobo ushyigikiwe ninyungu zidasanzwe dukoresha tekinoroji yihariye hamwe na patenti kugirango dukore ibikoresho byubucukuzi bwujuje ubuziranenge kandi buhenze binyuze mubufatanye. Ibicuruzwa bikoreshwa cyane mubucukuzi bw'amabuye y'agaciro, ibikorwa remezo, gucukura peteroli, amariba y'amazi hamwe n'ubwubatsi bw'ikirundo hamwe n'indi mirima. Nyuma yimyaka irenga icumi yubushakashatsi, ikintu cyihariye kiranga imyitozo ya HFD ni uko ikoresha ikoranabuhanga rishya rigezweho rya sima ya sima ya karbide, ishobora kugabanya kwambara, kongera ubuzima bwa serivisi no kugabanya guhagarika. Binyuze muburyo bwiza bwo kuvura ubushyuhe no kongera ubukana bwubuso, umubiri wa valve urakomera, ugakomera kandi ugakomera, bivuze imikorere isumba izindi nubuzima bwa serivisi ndende. Turashobora kandi gutanga igisubizo cyiza kubucukuzi bwawe, hamwe nubushobozi buhanitse hamwe nigiciro gito, cyangwa turashobora kubihuza nikibazo cyawe.
