Uburyo bwo gutera imbere mu buryo bwo kudatera imbere

Ibirango n'Ivyiza
(1) Uburebure bwo gutera ni 700mm, kandi uburebure bworoshe ni munsi ya 200mm. Uburemere bwinshi bw’abakinyi ni nk’ibiro 100, akenshi bikaba ari munsi y’ibiro 10.
(2) Ukwihangana kw’ingero z’ugutera ni 20mm ± 0.13mm, 100mm ± 0.30mm, 200mm ± 0,43mm, mu gihe ukuri kw’ingero y’igice gitoyi ntivyoroshe gushika munsi ya ± 0,10mm. Ukwihangana kw’imfuruka ni ± 0.5~ ± 2,0 degrees, kandi uburebure bukeyi bw’ugutera ni 0,5~1,5mm. Uburemere bw’ivyo gutera ni nk’i Rmax 4S~12S.
(3) Igikoresho co gupima ni hafi ata n’imwe ibuza, nk’ivyuma vy’aluminium, ivyuma vy’amabuye y’agaciro, ivyuma vy’ivyuma, ivyuma vy’ivyuma, ivyuma vy’umuringa, ubwoko bwose bw’ivyuma, cobalt - ishingiye ku bushuhe.
(4) Gukora ibikoresho vy’akazi bifise imiterere igoye, ubunini bwiza, gukata no gukora neza.
(5) Biga imyanda y’ibintu, kandi bishobora gukorwa mu bwinshi.
Ivyo bikoresho vy’ubuhinga bwa none bikoreshwa cane muri moteri z’indege, ibikoresho vy’umuyagankuba, ibihimba vy’umuyagankuba, ibihimba vy’indege, imodoka, moteri z’umuriro, imodoka, imashini y’ibifungurwa, imashini zicapura impapuro, ibikoresho vyo gukora ama valve, amaroboti, imashini zo kudoda, imashini zo kudoda, imashini zo gucuruza, n’ibindi bihimba vy’imashini.
2-2 Uburyo
Hari ubwoko bubiri bw’uburyo bwo gutera imbere: uburyo bukomeye (Solid Mold) n’uburyo bw’ivyuma vy’ivyuma (Ceramic Shell Mold), ubwa nyuma ni uburyo bwo gutera imbere bw’ivya mbere.
Uburyo bukomeye bwo gupfa butuma ibibumbano bisa n’ubunini bwa nyuma bwo gutera inyuma y’aho kwihweza ukuntu ivyuma vy’ivyuma vy’ibara ry’agahama bigenda biragabanuka be n’uko ivyuma vy’ivyuma bihungabana. Ico gipfukisho gishongejwe gisutswe mu gitereko gikozwe mu cuma canke c’ivyuma bita silica. Uhejeje gukuraho ubwoko bw’ibishashara, ushireko ifu n’ugufatanya. Uhejeje gutonyanga, ushiremwo ivyuma bikomeye maze ubimize. Ushire mu gipfukisho c’abakinyi, wuzuze ifu n’ibindi bifatanya, hanyuma wume. Hanyuma uyishushanye kugira ngo ishonge ibishashara biva mu gitereko. Shusha igitereko ku bushuhe bwinshi, ushireko umunyuro mutoyi w’ibishashara maze wongere inkomezi zawo, hanyuma utere umuyagankuba.
Uburyo bwo gukoresha igikoko c’amabuye gushika ubwo bwoko bw’ibishashara ni nk’uburyo bukomeye, ariko inyuma y’umusenyi n’umusenyi (canke umusenyi ureremba), atari igikorwa co kubumbabumba, ariko ugasubira ku nkweto n’umusenyi gushika aho uburemere bw’igikoko bwari bwategekanijwe bwabonetse. Gushushanya, gushusha, gushongera mu gishari, ubushuhe bwinshi bushushanya hanyuma bikasuka, ubu buryo burakoreshwa cane mu bijanye n’ubuhinga bwo gutera imbere ubu, kuko bufise ivyiza bikurikira:
(1) Ugushikama kw'ingero nziza
(2) Gukoresha cane ibikoresho vyo guhagarika umutima .
(3) Uburemere bw’umuco, bworoshe gutwara, gufata, no gukora ibikoresho binini .
(4) Uburyo bwo gukora bushobora gukoreshwa mu buryo bwikora kugira ngo umuntu azigame inguvu z’abantu no gutuma igipimo c’uguhingura .
(5) Igiciro gitoyi co gukora
(6) Igipande c’ivyuma c’ivyuma ni gito cane, kandi igitigiri c’ugukonjesha c’ugutera inyuma yo gusuka ni kinini cane kandi ni co kimwe, rero imiterere yayo y’ubuhinga ni yo nziza.
(A) Icitegererezo c'Umukuru (Icitegererezo ca Master)
Igishushanyo c’ico kigereranyo nyamukuru kirasa n’igicuruzwa ca nyuma. Ivyo gutera imbere n’ugucika intege kw’ibishashara, no gushusha no kwaguka be n’ugutera imbere n’ugucika intege kw’ibumba ry’uguterera bitegerezwa kwiyumvirirwa mu cuma co gutera. Nk’akarorero, iyo igipimo c’ugugabanuka kw’ubwoko bw’ibishashara ari 1,2%, igipimo c’ukwaguka kw’ubushuhe bw’ibikoresho vyo gutera ni 0,7%, kandi igipimo c’ivyuma vy’ivyuma vy’ivyuma ni 1,7%, igitigiri c’ukwiyongera kw’ubunini bw’ikigereranyo nyamukuru ni 2,2%, kandi ibikoresho bikoreshwa cane ni aluminium andoy n’umuringa .
