Isekurume y'intama igabanijwemo ubwoko bubiri: ubusa kandi bukomeye.Impfizi z'intama zidakoreshwa zikoreshwa mumashini ya truboni.
Impfizi y'intama muri rusange ni silindrike muri rusange, ishobora kugabanywamo impera, imizi n'imizi.
Kuri tonnage nini ya extruders, impfizi zintama zakozwe mubice bihinduka kugirango byongere imbaraga ndende.Muri iki gihe, silinderi yo gukuramo igomba kugira umwobo w'imbere hamwe n'impinduka zinyuranye.
Diameter yo hanze yintama yo gukuramo igenwa ukurikije diameter y'imbere ya silinderi.
Diameter yinyuma yintama yo gukuramo ya horizontal isanzwe ni nini kuruta iy'intama y'intama.Diameter y'imbere ya silinderi ni 4-10mm nto.
Uburebure bwimpfizi y'intama bingana n'uburebure bw'intama yo gushyigikira intama hiyongereyeho uburebure bwa silinderi yo gukuramo hiyongereyeho 5 kugeza kuri 10mm, kugirango usunike umuvuduko ukabije (reba ibikoresho bisigara bya extrusion) hamwe na gaze ya gaz isohoka muri silinderi.Ibikoresho byo gukuramo impfizi y'intama ni chrome-nikel-molybdenum na chrome-nikel-tungsten.Umubiri winkoni wateranijwe ukorwa muri chromium-nikel-tungsten-vanadium ivanze, kandi umuzi ugizwe na chromium-nikel-molybdenum.
Isekurume y'intama ikorerwa guhangayikishwa cyane no kunanirwa mugihe cyo gukora.Kubwibyo, gutuza no
imbaraga zintama zintama zigomba kugenzurwa mugihe cyo gukuramo.
