Daga mahangar samar da samfuran filastik, ana amfani da nau'in busa extrusion don haɓakawa, sanyaya, da kuma tsara parison, yayin da yake baiwa mai zanen siffar da girman da ake so.The extrusion busa mold yana da wadannan halaye.

(1) Extrusion busa gyare-gyaren gyare-gyare, sai dai na musamman na musamman irin su samfurori masu bango biyu, kawai suna da rami na ƙirar mace kuma babu wani namiji.Idan aka kwatanta da gyare-gyaren da aka yi amfani da su a wasu kayan filastik, tsarin ya fi sauƙi.

(2) Tun da ƙirar ƙirar ba ta da ƙirar namiji, yana iya ƙaddamar da samfuran filastik tare da raguwa mai zurfi da siffofi masu rikitarwa.

(3) The mold rami ba shi da wani narke kwarara tashar, kuma mold aka rufe bayan parison shiga mold.Narkewar parison ya dogara da matsa lamba fadada iska don cika rami.

(4) Idan aka kwatanta da ƙirar allura, kogon busa mold ɗin extrusion yana ɗaukar ƙananan matsa lamba.Ana iya amfani da abubuwa masu nauyi don yin ƙura, kuma rami baya buƙatar taurare.The mold kudin ne in mun gwada da low.

(5) Ci gaba da samarwa, haɓakar haɓakar haɓakawa, da samfuran dogayen samfuran ana iya kera su;

(6) Ana iya samar da samfurori tare da sassa daban-daban;

(7) Haɗe tare da wasu kayan aiki, zai iya kammala cikakken aiki na matakai daban-daban.Alal misali, injin zane da na'ura na calending sun hada kai don samar da fim din;

(8) Shugaban extruder da pelletizer na iya yin aiki tare don pelletize;

(9) Wurin yana da ƙanƙanta kuma yanayin samarwa yana da tsabta.
