Ukusuka kwimbono yokuveliswa kweemveliso zeplastiki, i-extrusion blow mold isetyenziselwa ukunyuka, ukupholisa, kunye nokubumba i-parison, ngelixa unika umyili umzobo kunye nobukhulu obufunwayo.I-extrusion blow mold inezi mpawu zilandelayo.

(1) Izinto zokubumba zokubumba ezivuthelweyo, ngaphandle kobunjwa obukhethekileyo njengeemveliso ezinodonga oluphindwe kabini, zinendawo yokungunda yabasetyhini kwaye akukho ngundo yindoda.Xa kuthelekiswa nokubumba okusetyenziswe kwezinye iimveliso zeplastiki, isakhiwo silula kakhulu.

(2) Ekubeni i-mold structure ingenayo i-mold yendoda, inokuthi ifake iimveliso zeplastiki kunye neendawo ezinzulu kunye neemilo ezinzima.

(3) Umngxuma wokungunda awunamjelo wokunyibilika, kwaye ukungunda kuyavalwa emva kokuba i-parison ingene kubumba.I-parison yokunyibilika ixhomekeke ekwandisweni komoya okucinezelweyo ukuze kuzaliswe umngxuma.

(4) Xa kuthelekiswa ne-injection mold, i-extrusion blow mold cavity ithwala uxinzelelo oluphantsi.Izinto ezilula zingasetyenziselwa ukwenza isikhunta, kwaye i-cavity ayifuni ukuqina.Ixabiso lokungunda liphantsi.

(5) Imveliso eqhubekayo, ukusebenza kakuhle kwemveliso, kunye neemveliso ezinde zingenziwa;

(6) Iimveliso ezinamacandelo ahlukeneyo zinokuveliswa;

(7) Idityaniswe nezinye izixhobo, inokugqiba inkqubo ebanzi yeenkqubo ezahlukeneyo.Ngokomzekelo, umatshini wokuzoba kunye nomatshini wokubhala i-calendering uyasebenzisana ukuvelisa ifilimu;

(8) Intloko ye-extruder kunye ne-pelletizer zinokusebenzisana ukwenza i-pellets;

(9) Indawo incinci kwaye indawo yemveliso icocekile.
