Imishini yokumaka emgwaqweni ingamadivayisi afaka izimpawu emigwaqweni, njengemigqa, imicibisholo, izimpawu, njll. Isetshenziselwa isiqondiso sethrafikhi, ukuphepha, kanye nezinjongo zokuhlobisa.Imishini yokumaka emgwaqeni ingasebenzisa izinhlobo ezahlukene zezinto, ezifana ne-thermoplastic, upende obandayo, ipulasitiki ebandayo, njll. Kuye ngezinto ezibonakalayo kanye nendlela yokufaka isicelo, ukushuba komugqa kungahluka kusuka ku-1 mm kuya ku-4 mm noma ngaphezulu.

Enye yezinto ezithinta ukushuba komugqa yibhokisi le-screed noma idayi.Lena ingxenye yomshini ebumba impahla ibe umugqa njengoba ikhishwa eketelani noma ethangini.Ibhokisi le-screed noma idayizi linembobo enquma ububanzi nobukhulu bomugqa.Ngokulungisa usayizi wokuvula, ubukhulu bomugqa bungashintshwa.Isibonelo, ukuvuleka okuncane kuzokhiqiza umugqa omncane, kanti ukuvuleka okukhulu kuzokhiqiza umugqa omkhulu.

Esinye isici esithinta ukushuba komugqa ijubane lomshini.Uma umshini uhamba ngokushesha, umugqa uzoba mncane, futhi ngokuphambene nalokho.Lokhu kungenxa yokuthi izinga lokugeleza kwempahla lihlala njalo, kodwa ibanga elimbozwe umshini ngesikhathi seyunithi liyahlukahluka.Isibonelo, uma umshini uhamba ngo-10 km/h futhi usebenzisa u-10 kg wezinto ezibonakalayo ngomzuzu, ukujiya komugqa kuzohluka kunalapho uhamba ngo-5 km/h futhi usebenzisa inani elifanayo lempahla ngomzuzu.

Isici sesithathu esithinta ukushuba komugqa izinga lokushisa lempahla.Izinga lokushisa lithinta i-viscosity kanye ne-fluidity yezinto, okubuye kuthinte indlela esakazeka ngayo emgwaqeni.Isibonelo, impahla ye-thermoplastic idinga ukushiselwa ezingeni lokushisa eliphezulu (cishe u-200°C) ukuze ibe uketshezi futhi igeleze kahle ebhokisini le-screed noma idayizi.Uma izinga lokushisa liphansi kakhulu, impahla izoba nkulu kakhulu futhi kube nzima ukuyikhipha, okuholela emugqeni omkhulu futhi ongalingani.Uma izinga lokushisa liphezulu kakhulu, impahla izoba mncane kakhulu futhi igijime, okuholela emugqeni omncane futhi ongajwayelekile.

Ukufingqa, imishini yokumaka umgwaqo ingalungisa ukushuba komugqa ngokushintsha ibhokisi le-screed noma usayizi wokuvula ukufa, isivinini somshini, kanye nezinga lokushisa lempahla.Lezi zici zidinga ukulingana futhi zilinganiswe ngokuya ngemininingwane nezidingo zephrojekthi ngayinye.
