Inkqubo intshayelelo
I-3/4 yeemveliso ezibunjiweyo zenziwe nge-extrusion yokubumba. Inkqubo ye-extrusion kukunyanzela umbandela ngomngxunya okanye ukufa ukuze wenze imveliso.

Inkqubo yokubumba yokuqhuma inamanyathelo ama-5: 1. I-preform yeplastikhi (i-extrusion yetyhubhu yeplastiki engenanto). 2. Vala isikhunta esikwi parison, bamba ukungunda kwaye usike iparison. 3. Vuthela ukungunda kudonga olubandayo lwendawo, uhlengahlengise ukuvulwa kwaye ugcine uxinzelelo oluthile ngexesha lokupholisa. 4. Vula isikhunta uze ususe iinxalenye ezivuthelweyo. 5. Coca umbane ukuze ufumane imveliso egqityiweyo.

Inkqubo yokubumba engenanto engenanto
I-extrusion engenanto yokubumba kukunyibilikisa kunye neplastikhi yeplastiki kwi-extruder, emva koko ukhuphe i-parison ye-tubular nge-tubular die. Xa iparison ifikelela kubude obuthile, iparison ishushu ngumoya wokubetha. Umoya ocinezelweyo emva koko uvuthelwa ngaphakathi ukuze wenze iparison isondele eludongeni lwesikhunta somngundo ukufumana ubume bomphunga, kwaye phantsi kwemeko yokugcina uxinzelelo oluthile, emva kokupholisa kunye nokubumba, imveliso evuthelweyo ifunyenwe ngokudilizwa. Inkqubo extrusion yokubetha ngegalelo ngolu hlobo lulandelayo.
Iplastikhi → ukufaka iplastikhi kunye nokukhutshwa → i-parison ye-tubular → ukuvalwa komngundo → ukunyuka kwamaxabiso → ukupholisa → ukuvulwa komngundo → kukhuphe imveliso
I-extrusion yokubetha ukubetha inokwahlulahlulwa ngokwala manyathelo mahlanu alandelayo, njengoko kubonisiwe kumzobo 1-1.
I-polymmer iyanyibilika nge-extruder, kwaye unyibilike ubunjwe sisidudu ngethumbu.
Xa iparison ifikelela kubude obumiselwe kwangaphambili, ukungunda kuvaliweyo, iparison ixinaniswe phakathi kweziqingatha ezibini zokubumba, kwaye iparison iyanqunyulwa isiwe kwesinye isikhululo.
Faka inaliti yomoya oxineneyo ungene parison ukuze uyenze iparison ukuyenza isondele kwisakhelo sokubumba.
④ Phola.
PVula ukungunda kwaye ukhuphe imveliso ebunjiweyo.
