Igishushanyo mbonera cy'imirongo n'ingano yayo:Garagaza inguni y'umuyoboro, icyuho cy'umuzi, isura y'umuzi, n'uburyo bwo gutegura kugira ngo umenye neza ko uhumetse neza kandi ukomere.
Ibisabwa ku bunini bwa weld:Sobanura ubunini bw'umuhogo wo gusudira, ingano y'amaguru, uburebure bw'umuhogo wo gusudira, n'ibisabwa mu gukomeza ukurikije amahame ngenderwaho y'imiterere.
Aho gusudira:Shaka ahantu ho gusudira, harimo gusudira mu buryo butambitse, butambitse, buhagaze, n'ubwo hejuru, kugira ngo urebe neza uburyo bwo gusudira bukwiye.
Ireme ry'Ubusode:Gushyiraho ibipimo ngenderwaho byo kwemerwa n'ibisabwa mu igenzura hashingiwe ku bipimo by'umushinga n'amahame mpuzamahanga.
Gutunganya Gukubita
Gupfumura ni bumwe mu buryo bw'ingenzi mu gutunganya ibyuma, butuma habaho imyobo ku byuma by'icyuma mu buryo bwa tekiniki cyangwa mu buryo bufatika nk'uko bigaragara mu gishushanyo cyangwa igishushanyo mbonera cy'ubuhanga. Iyi myobo ikoreshwa cyane cyane mu guhuza ibyuma, gushyiraho imigozi, gushyira imiyoboro no kuyishyiramo ibikoresho, kandi iyi myobo igira uruhare runini mu guteranya neza no gukora neza kw'imiyoboro.
Uburyo bwo gukubita n'ibisabwa
Mbere yo gukubita cyangwa gucukura, ibipimo by'umwobo bigenwa hashingiwe kuibishushanyo mbonera by'inyubako, ibishushanyo mbonera by'ubukorikori, n'ibisabwa mu mushinga, harimo:
Aho Umwobo Uherereye: Sobanura aho umwobo uherereye neza ukoresheje ingano za coordinates kugira ngo urebe neza uko uhagaze mu gihe cyo guteranya.
Umubare w'imyobo: Garagaza ingano ikenewe n'uburyo imyobo iteye hakurikijwe imiterere y'aho ihurira.
Umwanya w'umwobo: Kumenya ingano z'umwobo ukurikije ibipimo bya bolt, ubwoko bw'imiyoboro, n'ibipimo ngenderwaho by'ubuhanga.
Ibisabwa mu bijyanye n'ubunyangamugayo:
Umwobo usanzwe w'amaboliti:kwihanganira ubusanzwe biri hagati ya ± 1 mm
Umwobo w'amaboliti ukomeye cyane:ibisabwa byoroshye cyane, ubusanzwe biri hagati ya ± 0.5 mm
Ubwoko bw'umwobo:Hitamo imiterere y'umwobo ikwiye, harimo:
Uburyo butandukanye bwo gutunganya ubuso nko gusiga irangi, gusiga ibyuma bikoresha amashanyarazi (galvanizing) bukoreshwa kuriinyubako z'ibyumakunoza imikorere yayo kurikurinda ingese, gukumira ingese, kuramba no kugira ubwiza.
Gutunganya ibyuma
Itanga ubushobozi bwo kurwanya ingese no kurinda igihe kirekire, ikwiriye ahantu ho hanze no mu bidukikije bikomeye.
Igipfundikizo cy'ifu
Itanga amabara menshi atandukanye, irwanya ikirere cyane, kandi ifite irangi ryiza ku buso.
Gusiga epoxy
Itanga uburyo bwiza bwo kurwanya ingese no kurwanya imiti, ikaba nziza cyane mu bidukikije bigoye.
Igipfukisho gikungahaye kuri Epoxy Zinc
Ikoresha zinc nyinshi kugira ngo irinde ingese neza hakoreshejwe amashanyarazi.
Gushushanya
Igisubizo cyoroshye kandi gihendutse gifite amabara atandukanye n'irangi rijyanye n'ibyo umushinga ukeneye.
Igipfukisho cy'amavuta y'umukara
Uburyo buhendutse bwo kurinda ingese mu gihe cyo kubibika, kubitwara, cyangwa kubikoresha igihe gito.
Itsinda ryacu ry’abahanga mu by’ubwubatsi bakuru n’inzobere mu bya tekiniki rifite uburambe bwinshi mu mishinga n’ibitekerezo bigezweho byo gushushanya, kandi rizi neza imiterere y’ibyuma n’amahame ngenderwaho mu nganda.
Dukoresha porogaramu z'ubuhanga mu gushushanya, harimoImiterere ya AutoCAD na Tekla, guteza imbere sisitemu yuzuye yo gushushanya amashusho igaragaza neza ingano y'ibice, imiterere y'uduce, n'imiterere y'ahantu, kuva kuri moderi za 3D kugeza ku bishushanyo bya 2D by'ubuhanga.
Serivisi zacu zikubiyemo inzira yose yo guteza imbere umushinga, kuva ku gishushanyo mbonera cya mbere kugeza ku bishushanyo mbonera by'ubwubatsi birambuye, kuva ku isesengura rito ry'uduce kugeza ku igenzura rusange ry'imiterere.
Dugenzura neza buri kantu kose, tugera ku buhanga bungana na milimetero kugira ngo twizere ko imirimo yo kubaka ikora neza kandi ishoboka cyane.
Duhora twibanda ku bakiriya. Binyuze mu kugereranya ibisubizo no kwigana imyitwarire y’imashini, dutegura ibisubizo bihendutse byo gushushanya ku bikorwa bitandukanye (inganda, amazu y’ubucuruzi, ibiraro, n’inzira z’abanyamaguru, nibindi). Mu gihe twita ku mutekano w’inyubako, tugabanya ikoreshwa ry’ibikoresho kandi tworoshya inzira z’ubwubatsi. Dutanga serivisi zirambuye nyuma yo kugurisha, kuva ku gukurura kugeza ku buyobozi bwa tekiniki aho bikorerwa. Ubunyamwuga bwacu busobanura ko ushobora kutwizera; tuzatanga buri mushinga wose w’inyubako z’icyuma ku gihe. Twabaye umufatanyabikorwa wizewe mu gushushanya ahantu hamwe.
Gupakira no gutwara neza ni ingenzi kugira ngo ibyuma birinde kwangirika, ingese, no guhinduka mu gihe cyo kubitwara no kubitanga.
Uburyo bwo gupakira
Ibice by'icyuma bifatanye kandi bigashyirwaho imigozi y'icyuma kugira ngo bipakire kandi bipakururwe neza.
Ubuso burinzwe n'ibikoresho bidapfa amazi kugira ngo hirindwe ubushuhe n'ingese.
Ibice byashyizweho ikimenyetso cy'ibirango, ibishushanyo, n'imibare y'ibiranga kugira ngo byoroshye guteranya.
Ibisubizo by'uburyo bwo gupakira ibintu byihariye biraboneka hakurikijwe ibisabwa n'umushinga ndetse n'imiterere y'ubwikorezi.
Uburyo bwo gutwara abantu
Imizigo yo mu mazi:Uburyo busanzwe bwo kugeza ku rwego mpuzamahanga inyubako nini z'ibyuma, hakoreshejwe amakontena cyangwa amato manini.
Ubwikorezi mu muhanda:Bikwiriye gutangwa no gutwarwa mu buryo bw'ibanze kw'ibikoresho by'icyuma byateguwe.
Gupakira no gutwara ibikoresho by’abahanga bireba ko ibikoresho by’icyuma bihagera neza, bigakomeza kugira ubuziranenge, kandi bigafasha gushyiraho neza aho bikorerwa.
Ubwikorezi:Gutanga ibicuruzwa mu buryo bwa "Express Delivery", "Air, Gari ya moshi", "Land", "Gari ya moshi", "Meli" (FCL cyangwa LCL cyangwa Bulk)
Kuva ku gutanga kugeza ku byiciro, itsinda ryacu ry’inzobere riri kumwe namwe mu mushinga mwiza kandi utunganye. Dutanga ubufasha mu bya tekiniki, umufasha mu gushyiraho no gutanga serivisi zo mu murima kugira ngo tunoze gahunda z’ubwubatsi kandi twizere ko inyubako z’ibyuma zirangwa n’umutekano, ihamye n’ubwiza.
Mu gihe cyo kugurisha, dutanga inama zo kubungabunga, amabwiriza yo kwita ku bicuruzwa ndetse n'ubujyanama mu bya tekiniki hakurikijwe imiterere y'icyuma. Niba hari ikibazo kirimo, nyuma yo kugurisha tuzahita dusubizwa kandi hagatangwa inama ku bisubizo by'abahanga kugira ngo imiterere y'icyuma ikomeze gukora neza kandi abakiriya banyurwe.
Q: Ni ubuhe bwoko bw'ibyuma mutanga?
A: Dutanga ibisubizo bitandukanye by’imiterere y’icyuma, harimo ububiko bw’ibyuma, amaduka, inyubako z’inganda, imbaho z’ibyuma, ibiraro, n’inyubako z’ibyuma zikozwe mu buryo bwihariye hashingiwe ku bisabwa mu mushinga.
Q: Ese inyubako z'ibyuma zishobora guhindurwa?
A: Yego. Dutanga ibisubizo byihariye bishingiye ku bishushanyo byawe, ingano, ibisabwa mu mutwaro, imiterere y'igishushanyo, n'imiterere y'umushinga.
Q: Ni gute wakwizeza ko imiterere y'icyuma ari myiza?
A: Dukora igenzura rikomeye ry’ubuziranenge mu gihe cyose cy’ubukorikori, harimo kugenzura ibikoresho, kugenzura gusudira, kugenzura ingano, kugenzura gutunganya ubuso, no gupima ubuziranenge bwa nyuma.
Q: Inyubako z'ibyuma zipakirwa zigatangwa gute?
A: Ibice by'icyuma bihambirwa neza, bigashyirwaho ikimenyetso, kandi birinzwe n'ibikoresho bidapfa amazi mbere yo koherezwa. Uburyo bwo gutwara ibintu burimo gutwara ibintu mu mazi hakurikijwe ibyo umushinga ukeneye.
Q: Ese mutanga ubufasha bwo gushyiramo ibikoresho no kubitanga nyuma yo kugurisha?
A: Yego. Dutanga ubuyobozi bwa tekiniki, ubufasha mu gushyiraho, inama zo kubungabunga, na serivisi z'umwuga nyuma yo kugurisha mu gihe cyose cy'umushinga.
