一, Ibibazo by'imiterere y'utugari (Ibibazo by'ibanze)
1.Imiterere ya selile idahwanye (itandukanye mubunini)
Fenomenon: Umusaraba - igice cyibicuruzwa byerekana uruvange rutandukanye rwingirabuzimafatizo nini nini, hamwe no gukwirakwiza bidasanzwe, bigira ingaruka kumyumvire yintoki hamwe nubukanishi bwibicuruzwa.

3) Viscosity idahuye nuruvange rwa reberi: Niba ubwiza bwikigo cya reberi ari hejuru cyane, kurwanya kwimuka no guhuza ibibyimba munganda ya reberi ni binini, kandi biroroshye gukora ibibyimba bifite ubunini butandukanye. Niba ibishishwa biri hasi cyane, ibituba bikunda kureremba no guhurira mubituba binini.
4) Kudahuza hagati y’ibirunga n'umuvuduko mwinshi: Iyi niyo mpamvu nyamukuru. Niba umuvuduko wifuro wihuta cyane kurenza umuvuduko wibirunga, ibituba bifite umwanya uhagije wo guhuza no gukura, bikavamo ubusumbane. Ibinyuranye, niba ibirunga byihuta cyane, ibituba bizakosorwa mbere yuko bikura, bishobora kuvamo ifuro ridahagije.
2. Gufunga {{1} rate igipimo cyakagari ni kinini cyane cyangwa kiri hasi cyane
Fenomenon: Ifunze ryinshi {{0} rate igipimo cyakagari: Igicuruzwa gifite imbaraga zo kwihangana ariko kidahoraho gihoraho, kandi cyunvikana. Igipimo kinini cyo gufungura: Igicuruzwa kiroroshye kandi gihumeka, ariko gifite imbaraga nke kandi gikunda kwikuramo no guhindura ibintu.
Impamvu:
1) Ifumbire mvaruganda: Imbaraga zubaka (modulus) ya silicone ubwayo nurufunguzo. Urukuta rurerure - rukomeye rwa rubber rugizwe nurukuta rwa firime rushobora kurushaho gukwirakwiza imyuka no gukora selile zifunze. Hasi {4}
)
3) Umuvuduko wibirunga: Umuvuduko wihuta wibirunga bifasha guhagarika imiterere yimikorere byihuse no gukora selile zifunze. Buhoro buhoro ibirunga biha ibituba umwanya munini wo kumena no guhuza, bikora imyenge ifunguye.
3.Ubushuhe ni bunini cyane cyangwa buto cyane
Fenomenon: Impuzandengo yubunini bwa selile itandukana nintego yo gushushanya.
Impamvu:
1) Igipimo cyumubyimba: Iyo wongeyeho ibintu byinshi, niko hasohoka gaze ninshi nubunini bwa pore.
2.
3) Kugenzura umuvuduko: Umuvuduko ukabije hamwe nigitutu cyo gutera inshinge bigira ingaruka kumyuka no gukura kwinshi. Kurekura umuvuduko byihuse bizatera ibituba kwaguka byihuse.
2, Ibibazo byubuziranenge
1.Ubuso bwuzuye, igishishwa cya orange, nibituba
Fenomenon: Ibicuruzwa bigaragara ntabwo byoroshye, hamwe nuburyo busa nigishishwa cya orange, ndetse nibibyimba bifite ibice byo hejuru birashobora kugaragara.
Impamvu:

3) Ubuso burangije kubumba: Niba ifumbire ubwayo idahwitse bihagije, bizongera ibibazo byubuso.
2. Uruhu rwo hejuru rushobora kuba rwinshi cyangwa ruto
Fenomenon: Ibicuruzwa bibyibushye mubisanzwe bifite uruhu rwinshi. Uruhu runini cyane rugira ingaruka ku bworoherane bwarwo, mu gihe uruhu ruto cyane rugira ingaruka ku mbaraga no ku isura.
Impamvu:
1) Ubushyuhe bwubushyuhe: Ubushyuhe bwububiko nurufunguzo rwo gukora uruhu. Ubushyuhe bukabije butera hejuru ya reberi yo hejuru hejuru yikaraga vuba, ikarinda ifuro no gukora uruhu ruto. Ubushyuhe bwububiko buri hasi, hejuru yibirunga bitinda, kandi gaze yabyaye imbere irashobora kuzamura urwego rwubuso, igakora uruhu runini.
2) Ubushuhe bwubushuhe bwibikoresho bya reberi: Ubushuhe bubi bwumuriro wa reberi burashobora gutuma habaho itandukaniro rinini ryubushuhe hagati yimbere ninyuma, byihutisha imiterere yuruhu.
3, Ibibazo bijyanye nubunini nibintu bifatika
1. Gutandukana kwinshi
Fenomenon: Ubucucike bwibicuruzwa bidahindagurika, cyangwa ubucucike butaringaniye mubice bitandukanye byibicuruzwa bimwe.
Impamvu:
1) Ingano yo gutera inshinge idahwitse: Iyi niyo mpamvu itaziguye. Ingano yo gutera inshinge kuri buri cyuho igomba kuba yuzuye kandi ihamye.
2) Inzira yo kubira ifuro idahindagurika: Ibibazo byose byavuzwe haruguru - byavuzwe haruguru (kutaringaniza, ubunini butandukanye) bizatera ihindagurika ryinshi.
3) Ibirunga bidahagije: Ibicuruzwa bifite ibirunga bidahagije bifite inkunga idahwitse kandi birashobora guhagarikwa cyane nyuma yo kumeneka, bikavamo indangagaciro zo gupima ubucucike.
2. Igipimo kinini cyo kugabanuka cyangwa guhindura ibintu
phenomenon: Igicuruzwa kigabanuka cyane nyuma yo gusenyuka, cyangwa guhindagurika no kugaragara.
Impamvu:
1) Imiterere y'utugari: Kubicuruzwa bifite imiterere ifunguye -, nyuma yo kumeneka, gaze y'imbere irahunga, bishobora gutera kugabanuka gukabije.
2) Ibirunga bidahagije: Ubucucike bwambukiranya ntabwo buri hejuru bihagije, ibice byurunigi rwa polymer ntibishobora gukosorwa neza, kandi igipimo cyo kugabanuka kiriyongera.
3) Gukonjesha kutaringaniye: Ibicuruzwa bimaze gukurwa mubibumbano, niba igipimo cyo gukonjesha ibice bitandukanye kidahuye, imihangayiko yimbere izabyara, biganisha kuri deformasiyo.
4) Igishushanyo mbonera: Igishushanyo mbonera cya ejector nticyumvikana, gitera ibicuruzwa guhinduka mugihe cyo gusohora.
3. Kwihangana guke no kwikuramo
phenomenon: Igicuruzwa ntigishobora gusubira muburyo bwacyo nyuma yo guhagarikwa, bikavamo indentations zihoraho.
Impamvu:
1) Imiterere y'utugari: Ikigereranyo kirenze urugero - igipimo cy'akagari nimpamvu nyamukuru itera kwikuramo burundu.
)
3) Imiterere yihariye ya reberi: Ibikoresho byatoranijwe bya silicone mbisi ya rubber ifite imbaraga nke.
