Uburyo bwo guhuza hagati yimbere yimbere yimbere ya barrale yo gukuramo hamwe nububiko bigomba gutoranywa ukurikije umusaruro wibicuruzwa bya aluminium.Kuri horizontal extruder, uburyo bubiri bwo guhuza bukoreshwa muri rusange: uburyo bwo gufunga kashe, ni ukuvuga, gufunga hagati ya silinderi yo gusohora no mumaso yanyuma yurupfu biri muburyo bwo guhuza indege.Ibyiza ni uko byoroshye gutunganya, byoroshye gukora, igitutu cyumutwe kumpera yanyuma yububiko no kumurongo wimbere ni muto, kandi ntabwo byoroshye guhonyorwa no guhinduka.Ikibi nuko imikorere ya kashe ari mibi.Niba imbaraga zo gukomera zidahagije, cyangwa ubuso bwo guhuza ntiburinganiye, icyuma cyahinduwe kizahita cyuzura kuva hejuru kugirango kibe "capa nini".
Gerageza kugumisha umurongo wa silinderi yo gukuramo, cyangwa ukoreshe gasike kugirango usukure umurongo mugihe.Niba igikoresho cyo gukuramo cyambarwa cyane cyangwa hari umwanda mugihuru cya silinderi yo gukuramo, umurongo wimbere ntusukurwa hamwe nisuku mugihe, kandi ntusimburwe mugihe, bizatera kugabanuka (kumpera ya bamwe ibicuruzwa biva hanze, nyuma yubugenzuzi bubiri bubiri, hariho ibintu bimeze nkamahembe mugice cyo hagati cyambukiranya igice, bita kugabanuka).
Niba umurongo w'imbere wa silinderi ya extrait yambarwa cyane, ifumbire ntishobora gukosorwa neza, bikavamo eccentricité, bizatera uburebure bwurukuta rutaringaniye rwumwirondoro wasohotse.
