Tshuab moulding, tseem hu ua hollow tshuab moulding, yog kev tsim cov yas ua sai sai.Tshuab molding txheej txheem Thaum Ntiaj Teb Tsov Rog II, tshuab tshuab tau pib siv los tsim cov polyethylene vials tsawg.Thaum xyoo 1950, nrog rau kev yug me nyuam ntawm high-density polyethylene thiab kev loj hlob ntawm tshuab moulding tshuab, tshuab moulding tshuab hauv Kunshan tau siv dav.Lub ntim ntawm hollow ntim tuaj yeem ncav cuag ntau txhiab litres, thiab qee qhov kev tsim khoom tau txais kev tswj hwm lub computer.Plastics haum rau tshuab moulding muaj xws li polyethylene, polyvinyl chloride, polypropylene, polyester, thiab lwm yam., thiab cov tau hollow ntim tau lug siv raws li industrial ntim ntim.
Raws li parison manufacturing txoj kev, tshuab moulding yuav muab faib ua extrusion tshuab moulding thiab txhaj tshuaj molding.Cov tsim tshiab muaj xws li ntau txheej tshuab moulding thiab stretch tshuab moulding.Lub tubular yas parison tau los ntawm extrusion los yog txhaj molding ntawm thermoplastic resin yog muab tso rau hauv ib tug phua pwm thaum nws kub (los yog rhuab mus rau softening mob), thiab compressed cua yog nkag mus rau hauv lub parison tam sim ntawd tom qab lub pwm raug kaw los tshuab yas parison. .Nws nthuav thiab lo ze rau sab hauv phab ntsa ntawm pwm, thiab tom qab txias thiab demolding, ntau yam khoom hollow tau txais.Kev tsim cov txheej txheem ntawm cov tshuab cua tshuab yog qhov zoo sib xws hauv cov hauv paus ntsiab lus rau tshuab molding ntawm cov khoom hollow, tab sis nws tsis siv pwm.Los ntawm kev xaav ntawm cov yas ua tshuab kev faib tawm, cov txheej txheem molding ntawm cov tshuab tshuab feem ntau suav nrog hauv extrusion.Cov txheej txheem tshuab moulding tau pib siv los tsim cov polyethylene vials tsawg-density thaum Ntiaj Teb Tsov Rog II.Thaum xyoo 1950s, nrog rau kev yug me nyuam ntawm high-density polyethylene thiab kev loj hlob ntawm tshuab moulding tshuab, tshuab moulding tshuab tau dav siv.Lub ntim ntawm hollow ntim tuaj yeem ncav cuag ntau txhiab litres, thiab qee qhov kev tsim khoom tau txais kev tswj hwm lub computer.Plastics haum rau tshuab moulding muaj xws li polyethylene, polyvinyl chloride, polypropylene, polyester, thiab lwm yam., thiab cov tau hollow ntim tau lug siv raws li industrial ntim ntim.
