Loj- nplai hollow yas tshuab moulding tshuab yog cov cav tov uas sib xyaw cov yas txhaj tshuaj molding tshuab nrog lub tshuab moulding thiab clamping mechanism ntawm lub hollow tshuab molding tshuab, absorbing thiab leveraging lub zog ntawm ob hom tshuab.
Qhov no ua rau muaj qhov hnyav parison repeatability, siab plasticizing muaj peev xwm, luv xim thiab cov khoom hloov lub sij hawm, thiab siab zog nyob rau hauv lub melt fusion cheeb tsam. Extrusion tshuab moulding tshuab feem ntau siv ib qho chaw cia- hom tuag lub taub hau, uas muaj cov txheej txheem sab hauv thiab ntau qhov chaw. Yog li ntawd, vim muaj cov yam ntxwv tseem ceeb ntawm kev khaws cia- hom tuag taub hau, lawv inevitably raug kev txom nyem los ntawm qhov tsis zoo xws li cov xim ntev thiab cov khoom hloov pauv sijhawm thiab qhov ntsuas tsis raug. Txhaj tshuab moulding tshuab, ntawm qhov tod tes, cais cov cia thiab txhaj tshuaj / extrusion parison ua haujlwm ntawm qhov chaw cia- hom tuag lub taub hau, uas yog tom qab ntawd los ntawm kev txhaj tshuaj plasticizing mechanism. Qhov no muab lub taub hau tuag qhov zoo ntawm lub taub hau tuag tas li, ua kom yooj yim xim thiab cov khoom hloov pauv.
