Nyob rau xyoo 2011 ncig 30% ntawm lub ntiaj teb cov khoom yas siv rau kev txhaj tshuaj molding, thiab kev siv tshuaj molding tshuab account rau li ntawm 40% ntawm tag nrho cov kev siv cov yas machinery, thiab tau ua ib lub yas ua thiab kev lag luam machinery, machinery khoom nyob rau hauv cov ceev tshaj plaws, ntau yam kev qhia, zus ntawm ntau tshaj plaws ntawm cov cav tov hauv ib qho.
2. Yas Extruder
Nyob rau hauv yas extrusion molding khoom, yas extruder yog feem ntau hu ua tus tswv tsev, thiab nws ancillary rov qab siv cov khoom yas extrusion tshuab hu ua auxiliary tshuab. Yas extruder Tom qab ntau tshaj li 100 xyoo ntawm txoj kev loj hlob, tau muab los ntawm tus Thawj Ib Leeg ntsia hlau ntsia hlau, ntsia hlau ntsia, thiab txawm tsis muaj hau ntswj thiab ntau hom qauv. NET, phaj (daim) khoom, profile, granulation, cable cladding thiab lwm yam yas moulding ntaws tshuab txuam, sib sau ua ntau hom ntawm plastering ntau lawm cov kab, ntau lawm ntau yam khoom yas. Yog li ntawd, yas extrusion machinery, tam sim no los yog yav tom ntej, yog dav siv nyob rau hauv kev lag luam yas kev lag luam ib qho ntawm lub tshuab.
3, Yas tshuab moulding tshuab
Tshuab Moulding khob Ua tshuab muaj ob theem pib no: Ua ntej moulding billet, thiab siv cov pa luam yeeb hlais {nrog tensile pas nrig] rau radial cua tshuab {thiab axial tensile} ntaus pob, kom nws txuas mus rau {stretch} Tshuab pwm kab noj hniav , pwm kab noj hniav zoo thiab qhov loj ntawm qhov khoom, thiab tos kom txias. Raws li molding txoj kev ntawm Parison, tshuab molding faib ua ob hom: extrusion tshuab molding thiab txhaj tshuab molding. Extrusion tshuab molding khoom (tshwj xeeb tshaj yog cov pwm) nws cov nqi thiab lub zog noj tsawg, qhov no yog ib qho ntawm nws qhov zoo, tuaj yeem tsim cov ntim loj ntim thiab cov qauv duab ntawm cov khoom, txhaj tshuaj tshuab moulding, muaj ntau dua qhov tseeb, tsis yog feem ntau seam, Feem ntau yuav tsis tsim cov tsos ntawm seem, zoo txuag khoom siv.
4. Zov Quav Tshuab Moulding
Muaj ntau txheej tshuab moulding ntawm lub khob tshuab raj, feem ntau, tag nrho cov extrusion tshuab molding thiab tag nrho kev txhaj tshuaj tshuab molding ob, ncab tshuab molding muaj kev txhaj tshuaj ncab tshuab molding thiab extrusion stretch tshuab molding ob hom. Lub tensile tshuab moulding tau muab faib ua ib kauj ruam thiab ob kauj ruam. Nyob rau hauv ib kauj ruam, molding, cua txias, cua sov, ncab thiab tshuab ntawm lub rooj sib hais thiab tshem tawm ntawm lub thawv raug ua tiav hauv ib lub tshuab, cov nqi khoom siv thiab kev siv zog tsawg tsawg, tuaj yeem siv rau cov khoom me me, ob kauj ruam, vim hais tias lub molding ntawm Parison thiab lub reheating ntawm billet, ncab thiab tshuab molding ntsig txog ob cov cav tov, high yield, tsim rau loj qhuav. Yas tshuab moulding tshuab tuaj yeem hais tias txoj kev lag luam ua rau kev loj hlob zoo tshaj plaws, dav siv nyob rau hauv ib qho ntawm lub tshuab, kev ntsuam xyuas kuj yog siab.
5, nias thiab hloov molding tshuab
Yas molding thiab hloov molding ntawm lub khob ua tshuab yog lub ntsiab molding txoj kev ntawm cov thermosetting plastics. Feem ntau rau cov compression molding xovxwm thiab hloov Moulding hloov molding tshuab yog thermosetting yas ua los ntawm ntau hom khoom yas, cov khoom siv tseem ceeb. Lub luag haujlwm ntawm cov xovxwm yog los ntawm cov pwm yas ntawm cov yas siab, yog siv hom tsau, tab sis kuj muaj qhov qhib thiab kaw pwm thiab lub luag haujlwm ntawm cov khoom ejector. Lub presses rau molding raug muab faib ua ob pawg: lub cev muaj zog presses thiab hydraulic presses. Vim hais tias ntawm cov neeg kho tshuab xovxwm ntawm lub chaw ua khoom, kev lag luam thiab kev kho yog ntau tshaj qhov hydraulic xovxwm, thiab tsis haum rau compacting loj yas qhov chaw, yog li maj tshem tawm. Tam sim no siv presses yeej hydraulic presses. Lub siab nruab nrab ntawm hydraulic xovxwm feem ntau muaj ob hom roj thiab dej, tus qub yog dav siv nyob rau hauv nruab nrab thiab me me-tsuas equipments. Hloov mould khoom siv tau nrog cov qub hydraulic xovxwm molding, tab sis kuj yuav siv tau rau kev hloov tshwj xeeb molding tshuab. Hloov cov tshuab molding yog ua tau ob chav siab hydraulic xovxwm nrog ob hydraulic kheej kheej. Raws li nws cov qauv tau faib ua qis thiab sab ob theem siab thiab txoj cai kaum ob hom.
