I-injection molding machine screw barrel idlala indima ephambili kwinkqubo yokubumba i-injection ye-PE (i-polyethylene) kunye ne-PP (i-polypropylene).Ukusetyenziswa kwayo kwezi zinto zimbini zidweliswe ngezantsi: Ukunyibilika kunye nokuxuba izinto eziphathekayo: I-screw barrel idlula kwi-screw ejikelezayo kunye nommandla wokufudumala ukufudumala ngokupheleleyo kwaye ucinezele i-PE okanye i-PP particles ukuze inyibilike kwi-melted flowable.Ngexesha elifanayo, indawo yokuxuba kwi-screw barrel inokuxuba izinto zeentlobo ezahlukeneyo ngokulinganayo ukuhlangabezana neemfuno zeemveliso ezithile.Uxinzelelo kunye nenaliti: Ngaphantsi kwesenzo se-screw barrel, i-PE etyhidiweyo okanye i-PP imathiriyeli ifakwe kwi-mold cavity ukwenza ubume bemveliso obufunwayo.Uxinzelelo kunye nesantya senaliti ye-screw barrel inokulungelelaniswa ngokweemfuno zemveliso ukuqinisekisa umgangatho weemveliso zokubumba inaliti.Ulawulo lobushushu kunye nokupholisa:
I-screw barrel idla ngokuxhotyiswa ngenkqubo yokulawula ubushushu ukuqinisekisa ukuba izinto ezityhidiweyo zihlala kwiqondo lokushisa elifanelekileyo.Ngelo xesha, emva kokuba i-injection igqityiwe, imveliso kufuneka idlule kwinkqubo yokupholisa ukuqinisa izinto kunye nokugcina imilo yayo.
Ukulawula kunye nokubeka iliso kwinkqubo yokubumba i-injection: I-screw barrel idla ngokuxhotyiswa ngenkqubo yokulawula kunye nokubeka iliso ukujonga iiparitha ezifana nobushushu, uxinzelelo kunye nesantya se-injection kunye nokulungelelanisa njengoko kufuneka.Oku kufaka isandla kumgangatho wemveliso ongaguqukiyo kunye nokusebenza kakuhle kwemveliso.
Ngamafutshane, i-screw barrel yomatshini wokubumba inaliti idlala indima ebalulekileyo kwinkqubo yokubumba i-PE kunye ne-PP, iqinisekisa ukuba izixhobo zinyibilika ngokupheleleyo kwaye zixutywe, kwaye ulawulo lwenkqubo yokubumba echanekileyo lufezekisiwe ukuvelisa umgangatho ophezulu. isitofu ukubumba iimveliso.
