Nyob rau hauv cov yas txhaj tshuaj molding, lub thoob thiab ntsia hlau, raws li cov khoom tseem ceeb ntawm cov txheej txheem txhaj tshuaj, ncaj qha txiav txim siab plasticizing zoo, metering raug, thiab pwm filling stability ntawm cov yaj, yog li cuam tshuam rau qhov tseeb qhov tseeb, qhov zoo sib xws, thiab kev ua haujlwm ntawm cov khoom tiav. Nrog rau kev xav tau ntawm kev lag luam ntau ntxiv rau siab -zoo, complex- cov khoom tsim, lub luag haujlwm ntawm lub thoob thiab cov ntsia hlau hauv kev txhim kho molding raug thiab kev ua tau zoo tau dhau los ua qhov tseem ceeb, dhau los ua qhov tseem ceeb rau kev nce qib ntawm kev txhaj tshuaj molding tshuab.
Lub thoob ua lub luag haujlwm tseem ceeb hauv kev ntim khoom zoo li qub thiab kev tswj xyuas thermal thaum lub sijhawm molding txheej txheem. Nws cov qauv cylindrical nrog qhov ntev ntev - txog - txoj kab uas hla muab qhov chaw sov txaus rau cov khoom siv yas, cia cov khoom siv maj mam hloov mus rau hauv homogeneous yaj thaum thauj. Los ntawm ntau-theem ywj siab cua sov thiab cua txias tshuab, lub thoob tuaj yeem tsim kom muaj qhov tseeb thiab tswj tau qhov kub thiab txias raws li cov kev taw qhia axial, ua tau raws li qhov xav tau ntawm thermal ua haujlwm ntawm cov khoom sib txawv thaum tsis txhob muaj cua sov hauv cheeb tsam uas ua rau degradation lossis underheating ua rau siab viscosity ntau dhau. Sab hauv phab ntsa tau hnav- tiv taus thiab corrosion- tiv thaiv kev kho mob thiab siab - precision machining, kom ntseeg tau ntev - lub sij hawm seem thiab kub hloov stability nyob rau hauv siab - kub thiab siab - siab ib puag ncig. Qhov no txo cov kev hloov pauv hauv cov dej tsis kam los ntawm cov phab ntsa sab hauv, muab kev txhim khu kev qha thermal ciam teb rau cov ntsia hlau plasticizing thiab metering txheej txheem.
Cov ntsia hlau ua lub luag haujlwm tseem ceeb hauv kev txhim kho molding raug thiab ua haujlwm zoo. Nws txoj kev sib hloov hloov pauv lub zog tsav mus rau hauv lub zog sab hauv thiab lub zog kinetic ntawm cov khoom, ua tiav tag nrho cov txheej txheem ntawm conveying, compacting, melting, mixing, thiab metering nyob rau hauv cov ntsia hlau channel. Qhov tsim nyog ntev - rau - txoj kab uas hla thiab qhov sib piv ntawm qhov sib piv tsim kom ntseeg tau tias cov khoom yog cov yas tag nrho thiab ncav cuag qhov zoo tshaj plaws viscosity nyob rau hauv ib qho kev mob stroke. Kev ua kom zoo ntawm cov ntsia hlau channel qhov tob thiab lub suab tswj lub zog shear thaum ua kom cov khoom xa tuaj, tiv thaiv cov shearing ntau dhau uas tuaj yeem ua rau cov khoom degradation lossis kub khiav. Cov qauv ntsia hlau tshwj xeeb xws li barrier-hom, tus pin- hom, lossis corrugated screws tuaj yeem tsim kho kom txhim kho qhov sib xyaw ua ke ntawm cov khoom ua tiav, ntau- cov khoom, lossis nyuaj - rau-plasticize tshuab, yog li txhim kho cov khoom zoo thiab kev ua tau zoo ntawm cov khoom tiav.
Cov nyhuv synergistic ntawm lub thoob thiab cov ntsia hlau tsim ib qho kev kaw, tswj tau, thiab zoo li plasticizing channel. Qhov ruaj khov thermal ib puag ncig ntawm lub thoob thiab lub zog lub zog ntawm cov ntsia hlau ua haujlwm ua ke los xyuas kom meej tias cov yaj muaj qhov kub thiab txias, viscosity, thiab lub xeev siab ua ntej kev txhaj tshuaj, txo qis qis qis thiab qis qhov sib txawv thaum lub sij hawm pwm filling, thiab txhim kho qhov zoo ntawm qhov tseeb thiab qhov zoo ntawm cov khoom tiav. Nyob rau tib lub sij hawm, optimized plasticizing efficiency shortens lub voj voog molding, tsub kom cov zis ib chav tsev lub sij hawm, thiab txo lub zog noj thiab ntau lawm nqi.
Kev nce qib ntawm cov ntaub ntawv thiab kev tsim cov txheej txheem rau niaj hnub txhaj tshuaj molding tshuab chim thiab screws, xws li daim ntawv thov ntawm siab - lub zog alloys thiab nto hardening tshuab, pab kom lawv muaj zoo heev hnav tsis kam thiab qaug zog kuj nyob rau hauv siab - ceev, siab - torque tej yam kev mob, ua kom ntev - lub sij hawm ua hauj lwm stability. Modular thiab hloov cov qauv tsim tso cai rau cov cuab yeej teb sai sai rau cov kev hloov pauv ntawm cov khoom sib txawv thiab cov khoom tshwj xeeb, txhim kho kev ua tau zoo thiab hloov pauv kev ua haujlwm.
Zuag qhia tag nrho, kev txhaj tshuaj molding tshuab chim thiab ntsia hlau ua lub luag haujlwm tseem ceeb hauv kev txhim kho molding raug thiab kev ua haujlwm zoo los ntawm kev tswj xyuas thermal ruaj khov, meej plasticizing, thiab kev ntsuas tau zoo. Kev ua kom zoo tsis tu ncua ntawm nws cov qauv tsim, kev tsim khoom, thiab kev saib xyuas yuav muab kev txhawb nqa zoo rau kev txhim kho ntawm kev txhaj tshuaj molding mus rau qhov siab dua, kev ua haujlwm siab dua, thiab cov txheej txheem ntse.
