Likotoana tsa ho seha mashala li entsoe haholo-holo ka 'mele oa motheo oa tšepe le hlooho ea ho seha motsoako o thata, ka thepa ea setso ea motsoako e nang le mabitso a mabitso a lebitso la YG11C kapa YG13C, e nang le metsoako e thata ea lithollo tse koahetsoeng. Ha ho rarahana ha mesebetsi ea merafo ea mashala ho ntse ho eketseha, k'hamphani ea rona e ntse e tsoela pele ho ntlafatsa theknoloji ea tlhahiso. Re amohetse thepa ea motsoako oa lithollo tse koahetsoeng tse mahareng tse nang le cobalt ea 7% ho isa ho 9%. Ka ho khetheha, re ntlafalitse thepa e meraro, KD205, KD254, le KD128, e etselitsoeng maemo a fapaneng a merafo. Lisebelisoa tsena li bontša botsitso bo botle, ho hanyetsa ho tsofala, le ho hanyetsa tšusumetso, li eketsa bophelo ba ts'ebeletso haholo le ho fumana kamohelo e phahameng har'a bareki ba rona.

Bakeng sa dikotwana tsa ho seha mashala, khamphani ya rona hajwale e ikgethile ka mehlala e fapaneng, ho kenyeletswa U82, U84, U85, U92, U95, U170, hammoho le dikotwana tsa mochini o tjhesang dithanele tse kang U135, U47, le S100. Re fana ka mefuta e fapaneng ya boholo ba bophara ba alloy, ho kenyeletswa 16, 18, 19, 20, 21, 22, 24, 25, 27, 28, 30, le 35. Dikotwana tsa ho seha mashala hangata di na le sebopeho sa cylindrical, ka bophara ba tsona bo ka tlase ho 22 bakeng sa ho seha mashala, ha bophara bo ka hodimo ho 25 bo sebediswa haholoholo bakeng sa ho seha mafika. Re na le mefuta e mengata ya dibopeho tse fumanehang, e re dumellang ho fana ka dihlahiswa tse ntle tsa alloy tse etseditsweng dikopo le ditlhoko tse fapaneng tsa bareki ba rona indastering ya merafo.
