Mu nganda zikora inganda, kwishyiriraho ibikoresho, no kubungabunga bisanzwe, gromets zikora nkumuhuza wingenzi no gutunganya ibice, kandi guhitamo kwabyo bigira ingaruka kumutekano no mumutekano. Guhitamo grommet iburyo bisaba gutekereza cyane kubintu bifatika, ibidukikije bisabwa, nibisabwa umutwaro. Ibikurikira bitanga ibyifuzo byo guhitamo umwuga.
Guhuza ibikoresho ni ngombwa. Ibicuruzwa bisanzwe bikozwe muri nylon, ibyuma (nk'ibyuma bitagira umwanda na aluminiyumu), na rubber. Ibikoresho bya Nylon biremereye kandi byangirika - birwanya, bigatuma bikenerwa muri rusange; ibyuma byibyuma birakomeye kandi birakwiriye ubushyuhe - ubushyuhe cyangwa hejuru - imizigo; na reberi ya reberi itanga ibintu byiza byo kwisiga kandi bikoreshwa mubikoresho byinyeganyeza. Ibikoresho bigomba guhuzwa nuburyo bukoreshwa. Kurugero, mu nganda zikora imiti, aside - na alkali - ibyuma birwanya cyangwa gromets zidasanzwe.
Ibipimo bifatika bigena kwizerwa. Imbere yimbere ninyuma, kimwe nubunini bwurukuta, rwa grommet igomba guhuza neza nibice bihujwe. Kurekura cyane grommet bizatera kurekura, mugihe cyane cyane grommet irashobora kwangiza ibikoresho. Emera kwihanganira bikwiye mugihe cyo gupima, reba amahame yinganda (nka ISO cyangwa ANSI ibisobanuro), kandi urebe niba bihuye binyuze mugupima icyitegererezo niba ari ngombwa.
Guhuza ibidukikije ni ngombwa. Ubushyuhe bwo hejuru - ubushyuhe, ubushuhe, cyangwa ibidukikije byangirika cyane bisaba kwitabwaho bidasanzwe: nikel - icyuma gikozwe mu byuma bisabwa gusabwa hejuru - ubushyuhe bukoreshwa; nylon hamwe na UV {{4} ating yihanganira gusabwa hanze; nibikoresho byujuje FDA nibindi byemezo byisuku birakenewe mubikorwa byibiribwa nubuvuzi.
Ikigeretse kuri ibyo, kubikoresho bikoresha imbaraga (nk'imashini zizunguruka), hagomba kwitonderwa kurwanya umunaniro wa gromets, hamwe nibikoresho - ibikoresho byo gukomera bikundwa kandi bigasuzumwa buri gihe kugirango byambare.
Guhitamo siyanse ya gromets ntabwo yongerera ibikoresho ubuzima gusa ahubwo binagabanya amafaranga yo kubungabunga. Abimenyereza bagomba gusuzuma byimazeyo ibikoresho, ingano, nibidukikije bishingiye kubikenewe byihariye kugirango umutekano ube mwiza.
