TL;DR — Ibintu by'ingenzi byafashwe

1. Abakora mu modoka bashyira ibizingo bya rubber mu byiciro A (bigaragara, zeru flash), B (bikora, flash ≤0.1mm), C (bifite ubuziranenge bwo hejuru, zeru munsi ya 10× magnification), na D (bifite umutekano, nta tunyangingo).

2. Gukuraho ibyuma bikoresha ikoranabuhanga na cryogenic deflashing bifasha mu buryo butandukanye — bikoresha ikoranabuhanga rijyanye na EPDM/NBR mu gihe cy’amasegonda 20-40, mu gihe cryogenic ikoresha icyuma gifata icyuma gikoresha icyuma cya silikoni na FKM kuva kuri -100°C kugeza kuri -130°C.

3. IATF 16949 ikurikiza ibisabwa bisaba ubushobozi bwo gukora inyandiko, mu gihe ASTM D2000 na SAE J300 bitanga urwego rwo gushyira mu byiciro ibikoresho byo gusibanganya ibifunga by'imodoka.

Sisitemu zo gufunga imodoka - imitako y'inzugi, imitako y'amadirishya, imitako ya moteri, n'impeta za O - zisaba imiterere ihamye kandi zitunganye neza. Ibisigazwa by'umukara bisigaye ku mitako ya rubber bishobora gutera ibibazo byo guteranya, inzira zo kuvaho, no kwangirika vuba.gusohora irabuinziraikuraho ibi bikoresho birengeje urugero bitabangamiye ubuziranenge bw'ibice, kandi kubera ko ikigo gishinzwe gutwara imodoka gishyira mu bikorwa amarembo meza cyane, gukuraho icyuho mu modoka bigena neza niba agace k'imashini karanyura cyangwa kananiwe kugenzura.

Ikibazo kiri mu kuringaniza imikorere myiza yo gusohora ifumbire no kubungabunga ibice byayo. Ifumbire z'imodoka akenshi zikorwa mu bikoresho bya elastomer bitanga umusaruro mwinshi nka EPDM, NBR, silicone, na fluoroelastomer (FKM) — buri kimwe gisubiza mu buryo butandukanye uburyo bwo gusohora ifumbire mu buryo bwa mekanike n'ubw'imashini. Kubera ko imiterere y'ibikoresho nk'imbaraga zo gucika n'ubushyuhe bw'ikirahure bitandukanye cyane, uburyo bwo gusohora ifumbire bugomba guhuzwa na elastomer ndetse n'ubuziranenge busabwa.

Iyi ngingo irasuzuma amahame ngenderwaho y’ubuziranenge akoreshwa kurigusohora irabu ku byuma bifunga imodoka, ikubiyemo ibipimo ngenderwaho byo kwemerwa n'urumuri, ibisabwa mu kurangiza ubuso, n'ubushobozi bw'ibikoresho bikenewe kugira ngo huzuzwe ibisabwa na OEM.
