Qhov sib txawv tseem ceeb ntawm extrusion thiab txhaj tshuaj molding yog tias extrusion tshuab moulding koom nrog extruding rhuab khoom, whereas txhaj tshuab cov khoom yuav tsum txhaj cov khoom rhuab rau hauv pwm.
tshuab moulding yog txheej txheem ntawm kev tsim thiab koom ua ke cov khoom yas hollow. Peb kuj tuaj yeem siv nws rau kev tsim cov iav fwj lossis lwm cov duab hollow. Feem ntau, cov txheej txheem tsim khoom siv peb hom txheej txheem molding: extrusion tshuab moulding, txhaj tshuaj molding, thiab txhaj tshuaj stretch tshuab molding. Feem ntau, thawj kauj ruam ntawm cov txheej txheem tshuab moulding yog softening yas los ntawm cua sov thiab ua rau nws mus rau hauv ib tug parison, uas yog ib tug raj zoo li ib daim ntawm cov yas nrog ib lub qhov nyob rau hauv ib kawg, cia lub compressed cua mus los ntawm. Tab sis kev txhaj tshuaj lossis txhaj tshuaj ncab txoj hauv kev tsim ua ntej.
Extrusion Tshuab Moulding yog dab tsi?
Extrusion tshuab moulding tuaj yeem piav qhia raws li hom tshuab moulding uas cov yas yog yaj thiab extruded rau hauv lub raj hollow los tsim ib lub parison (ib lub raj zoo li cov yas nrog lub qhov hauv ib kawg). Tom qab ntawd, lub parison yog ntes nyob rau hauv ib tug dej-txias hlau pwm, thiab cua yog tshuab mus rau hauv lub parison, inflating nws mus rau hauv lub hollow lub raj mis los yog lub thawv. Tom qab txias cov yas kom txaus, peb tuaj yeem qhib pwm kom tshem tawm ib feem.
Daim duab 01: (1. reciprocating ntsia hlau; 2. compressed cua; 3. hopper; 4. granules; 5. chim; 6. heaters; 7. sib tsoo, sib tov; 8. actuator's hydraulic generator; 9. kos phaj; 10. core/punch)
Feem ntau, ncaj qha extrusion tshuab moulding tuaj yeem piav qhia raws li txoj hauv kev ntawm cov khoom txav mus tom ntej, thiab nws zoo ib yam li kev txhaj tshuaj molding ntawm qee cov kauj ruam. Hauv cov txheej txheem no, peb tuaj yeem siv txoj kev accumulator, qhov twg lub accumulator sib sau cov yas yaj. Thaum cov pwm yav dhau los tau txias thiab thaum cov yas txaus tau sau tseg, ib tug pas nrig yog siv los thawb cov yas yaj, thiab nws tsim cov parison. Nyob ntawd, cov ntsia hlau tuaj yeem tig tsis tu ncua lossis sib nrug. Txoj kev txuas ntxiv ua rau qhov hnyav ntawm parison rub nws tus kheej, thiab nws ua rau calibrating phab ntsa thickness nyuaj.
Kev Txhaj Tshuaj Molding yog dab tsi?
Txhaj tshuab moulding yog txheej txheem muaj txiaj ntsig rau kev tsim cov iav hollow thiab cov khoom yas hauv ntau qhov ntau. Nws tseem yog luv luv raws li cov txheej txheem IBM. Nyob rau hauv cov txheej txheem no, lub polymer yog txhaj molded mus rau ib tug tub ntxhais pin uas yuav tig mus rau lub tshuab molding chaw nres tsheb uas yuav tsum tau inflated thiab txias. Txawm li cas los xij, kev txhaj tshuaj tshuab moulding yog txoj kev siv kawg ntawm peb txoj kev tshuab moulding. Feem ntau, nws muaj txiaj ntsig zoo hauv kev kho mob me me thiab ib lub raj mis. Cov txheej txheem no muaj peb kauj ruam hu ua txhaj tshuaj, tshuab, thiab ejection.
Daim duab 02: Tshuab Moulding
Lub tshuab txhaj tshuaj molding tshuab muaj lub thoob extruder thiab ntsia hlau sib dhos uas tuaj yeem yaj cov polymer. Tom qab ntawd, cov molten polymer yog pub rau hauv qhov kub khiav manifold thiab raug txhaj los ntawm nozzles rau hauv cov kab noj hniav uas muaj cua sov nrog rau cov tub ntxhais tus pin.
Qhov txawv ntawm Extrusion thiab Txhaj Tshuab Moulding yog dab tsi?
tshuab moulding yog txheej txheem ntawm kev tsim thiab koom ua ke cov khoom yas hollow. Feem ntau, cov txheej txheem tsim khoom siv peb hom txheej txheem molding: extrusion tshuab moulding, txhaj tshuaj molding, thiab txhaj tshuaj stretch tshuab molding. Qhov sib txawv tseem ceeb ntawm extrusion thiab txhaj tshuaj molding yog tias extrusion tshuab moulding koom nrog extruding cov khoom siv cua sov, qhov kev txhaj tshuaj tshuab yuav tsum txhaj cov khoom cua sov rau hauv pwm. Thaum extrusion tshuab moulding feem ntau tsim cov khoom 2D, txhaj tshuaj molding feem ntau tsim cov khoom 3D.
Cov hauv qab no infographic nthuav tawm qhov sib txawv ntawm extrusion thiab txhaj tshuaj molding hauv daim ntawv tabular rau kev sib piv ntawm ib sab.
Summary – Extrusion vs Txhaj Tshuab Moulding
Qhov sib txawv tseem ceeb ntawm extrusion thiab txhaj tshuaj molding yog tias extrusion tshuab moulding muaj extruding rhuab cov ntaub ntawv, whereas txhaj tshuab moulding yuav txhaj cov khoom rhuab rau hauv pwm. Tsis tas li ntawd, extrusion tshuab moulding feem ntau tsim cov khoom 2D, thaum txhaj tshuaj molding feem ntau tsim cov khoom 3D.
