Injongo yesi sahluko kukwazisa umfundi ngokubaluleka kwe extrusion uyafa uyilo kunye nobunzima obufanayo nomsebenzi. Ukukhutshelwa kubaluleke kakhulu kuyo yonke iplastiki. Ukongeza ekuboneleleni ngesitokhwe esiluhlaza njengephepha le-thermoforming kunye neepellets zokwenza inaliti yokubumba kunye nolunye ugcino lwangaphandle, iimveliso zokusetyenziswa ezininzi zenziwa nge-extrusion enjengefilimu, i-tubing, kunye neenkangeleko ezahlukeneyo. Nangona iintlobo zeemveliso ezikhutshiweyo zingahluka ngokumila ngokumangalisayo, kukho iseti yemithetho eqhelekileyo elawula uyilo lokufa olusisiseko. Umzekelo, kubalulekile ukulungelelanisa ukuhamba ukusuka kwindawo yokungena ukuya ekuphumeni, kwaye njengenyathelo elisebenzayo, ukucoca ibhalansi yokuhamba kunye nemilinganiselo yemveliso, izixhobo zokuhlengahlengisa ukuhamba zinokufakwa kuyilo lokufa. Iimveliso ezininzi ezizodwa zenziwa ngokukhutshwa kunye nokusweleka okufunekayo ukwenza ezi mveliso zihlelwe njenge: 1) iphepha liyafa; 2) ifilimu ethe tyaba kunye nefilimu evuthelweyo iyafa; 3) umbhobho kunye netyhubhu iyafa; 4) iprofayili extrusion iyafa; kunye ne-5) co-extrusion iyafa. Ngaphaya koko, uhlobo ngalunye lwemveliso lunezixhobo ezizodwa eziwela ezantsi kumgangatho wokufa ukuze zimise kwaye zipholise ukunyibilika okukhutshiwe. Ukunceda umfundi, imifanekiso eneenkcukacha yoyilo lokufa kunye nokuhambelana okupholileyo emazantsi kunye nokubumba izixhobo zekhompyutha kuyaboniswa. Ukuxela kwangaphambili iprofayili yokufa ukuze ufezekise ubungakanani bemveliso obunqwenelekayo ngumsebenzi onzima kakhulu kwaye ufuna ulwazi oluneenkcukacha ngeempawu zezinto ezibonakalayo kunye nokuhamba kunye neziganeko zokudlulisa ubushushu, kunye namava amaninzi ngokulungiswa kwe-extrusion. Uyilo lokufa lokukhutshelwa lusengaphezulu kobugcisa kunenzululwazi, nangona le yokugqibela iya isiba ngakumbi nangakumbi ngokufanelekileyo kulwakhiwo loyilo ngenxa yenkqubela phambili yamva nje kubalo olunamandla kunye nemodeli yokuhamba okuntsonkothileyo kunye neenkqubo zokudlulisa ubushushu, ngaphambi, emva, nasemva afe.
