Lub tshuab tshuab moulding, raws li lub npe qhia, yog lub tshuab siv los tshuab lub raj mis. Hauv cov ntsiab lus yooj yim, nws yog lub tshuab uas siv cov yas softened (xws li kua) los yog ua ntej - ua lub raj mis preforms thiab, los ntawm kev txawj ntse ntawm cov kws tshaj lij, tshuab rau hauv lub raj mis. Tam sim no koj nkag siab cov lus piav qhia yooj yim no, koj yuav tsum muaj kev nkag siab yooj yim ntawm tshuab moulding tshuab. Tom ntej no, cia saib cov yam ntxwv ntawm tshuab moulding tshuab. Tshuab tshuab moulding siv cov roj siab heev-pab airbag molding tshuab, tsis zoo li cov qauv molding cov qauv. Cov tshuab no tsis xav tau roj, txo cov roj noj thiab txo cov nqi. Tsis tas li ntawd, airbag molding thev naus laus zis muab kev sib khi zoo, muaj zog xauv lub zog, siab nruj, thiab tsis muaj zog thaum ua haujlwm. Qhov no kuj ua rau lub neej ntev dua rau tshuab moulding tshuab piv rau cov khoom qub.
Yuav kom nkag siab tiag tiag lub hauv paus ntawm tshuab moulding tshuab, cov txheej txheem thev naus laus zis koom nrog yog ib qho tseem ceeb ntawm cov khoom. Qhov tshwm sim ntxov tshaj plaws ntawm tshuab molding tshuab tuaj yeem taug qab mus rau Ntiaj Teb Tsov Rog II. Nyob rau lub sijhawm ua tsov ua rog, tib neeg pib tsim cov fwj me me ntawm - ntom polyethylene. Txawm hais tias cov txheej txheem tsim khoom ntawm cov fwj no zoo li yooj yim heev thiab tam sim no, tsis muaj tus nqi zoo nkauj, nws yog lub sijhawm ntawd cov neeg pib tshawb nrhiav txuas ntxiv ntawm tshuab moulding tshuab. The late 1950s saw the peak development of blow molding technology, due to the emergence of high-density polyethylene, which allowed for better shaping of the bottles. Los ntawm kev ua haujlwm ntev - lub sijhawm tsim khoom, cov txheej txheem tshuab moulding tau raug txhim kho thiab nthuav dav.
