Kufakwa ilebula eku-inthanethi noma okungaxhunyiwe ku-inthanethi ekubunjweni kwe-extrusion blow
Ukufaka ilebuli ngemuva kwemishini yokubumba ngokushaywa kungaholela ekulebhuleni kwelebula, ngenxa yokugoba ibhodlela. Kunezindlela ezahlukahlukene zokuthuthukisa / zokuxazulula lezi zinkinga.
Amapharamitha
The i-shrinkage yezinto ezibonakalayo kuncike kakhulu ezintweni ezisetshenzisiwe (uhlobo lweplastiki, i-masterbatch, njll.) kanye nejometry yebhodlela. Ukunciphisa i-parison kukhulisa i-shrinkage futhi. Lapho kukhulu i-parison, lapho okuthe thuthu kungaswelwanga lapho kuvunguza lokho kunciphisa ibhodlela lokugoba. I-shrinkage ingenzeka kuze kube ngamahora angama-72 ngemuva kokushaya ibhodlela!
The ilebula ukushuba ibalulekile futhi, ubukhulu, lapho ilebula izogobeka khona, ubuncane ithuba lokuthola imibimbi ngaphezulu kwelebula.
The uhlobo lweglue elisetshenzisiwe kwilebula nakho kubalulekile. Kunama-glues akhethekile, avumela ukuthi ilebula isashintshe, ngaleyo ndlela inxephezela ukushwabana.
The ilebula izinto kunomthelela wayo ku-shrinkage, izinhlobo ezahlukahlukene ezitholakalayo, iphepha, ipulasitiki, lapho le yokugcina inenzuzo yokuphinda isebenze futhi, inqobo nje uma ingumbhalo ofanayo.
Amalebula epulasitiki ajwayele ukuba ne-shrinkage 'ukumelana kangcono kunelebula lephepha.
