1. Khulisa umthamo womjovo, ofaneleka kakhulu ukukhiqizwa kwemikhiqizo enezimbotshana eziningi.Kwenziwe ngokwezidingo ezahlukahlukene, kunenzuzo enkulu ekukhiqizeni ukupakishwa, umgodi ojulile kanye nemikhiqizo ye-PET preform esheshayo.
2. Isikulufu esikhethekile se-PET sikhulisa isivinini sokuncibilika kanye nevolumu yomjovo, sinciphisa izinga lokushisa le-plasticizing, sithuthukise ngempumelelo ukushwabana kwe-preform futhi sithuthukise ukubonakala.
3. Khulisa i-thimble force kanye ne-ejection stroke, efaneleka kakhulu ekubunjweni kwe-PET preform ye-cavity ejulile.
