Yin sarrafa extrusion na karfe wata hanya ce mai mahimmanci ta matsa lamba bisa ga asalin ?arfe ?in filastik.Metruder ?arfe shine mafi mahimman kayan aiki don ?arancin ?arfe.

Extrusion yana ?aya daga cikin manyan hanyoyin don samar da ?ananan ?arfe da ba?in ?arfe da kayan ?arfe da ?ir?irar sassan. Hakanan hanya ce mai mahimmanci don shiri da sarrafa abubuwa daban-daban na ci gaba kamar su kayan ha?i da kayan foda.

Daga extrusion mai zafi na manyan sifa, ?arfe mai zafi na manyan sifofin tubular mashaya, extrusion mai sanyi na ?ananan ?angarori masu daidaito, ?arfafa kai tsaye da ?irar kayan ha?i tare da foda da ?ananan abubuwa kamar kayan ?asa, zuwa kayan aiki mai wahala irin su kamar yadda maha?an ke?a??u da kayan ha?in kai, aka yi amfani da fasahar extrusion ta zamani.

Hanyoyin sarrafa extrusion sune mafi ingancin extrusion, baya extrusion, lateral extrusion, gilashin lubrication extrusion, hydrostatic extrusion, ci gaba da extrusion.Extrusion sarrafa yana halin mai karfi uku-hanyar compressive compression, wanda yake taimakawa don inganta nakasawar filastik na ?arfe, inganta ingancin samfurin, inganta ?ananan kayan ciki da aikin samfurin.

Kari akan haka, sarrafa kayan masarufi kuma yana da aikace-aikace da yawa, sassaucin samarwa, sauki tsari da karancin saka jari ga kayan aiki.

Abubuwan da ba ?arfe ba tare da ?ananan narkewar narkewa, kamar gami na aluminum da allo, sune kayan da aka fi amfani da su a ciki sarrafa extrusion.
