Txhaj Moulding txheej txheem ntawm HDPE
Cov txheej txheem txhaj tshuaj molding yog ib txoj kev siv dav siv los tsim cov khoom HDPE nrog kev ua haujlwm siab thiab ua haujlwm zoo. Cov kauj ruam muaj xws li:
Pub thiab Melting
Raw HDPE pellets yog loaded rau hauv lub hopper, los ntawm qhov chaw lawv muab pub rau hauv ib lub rhuab chim chim.
Nyob rau hauv lub chim, cov pellets yog maj rhuab, melted, thiab uniformly tov.
Txhaj tshuaj
Ib lub taub hau reciprocating tsav lub molten HDPE los ntawm lub nozzle rau hauv pwm kab noj hniav nyob rau hauv siab.
Lub pwm kab noj hniav yog tsim raws li qhov sib txawv ntawm cov khoom kawg, kom ntseeg tau qhov tseeb qhov tseeb.
Cooling thiab Solidification
Thaum cov molten polymer puv cov pwm, nws raug tso cai kom txias thiab khov.
Kev tswj kom txias kom ntseeg tau tias qhov chaw khaws cov pwm zoo, txo qis warpage lossis shrinkage.
Tshem tawm
Tom qab txaus txias, lub pwm qhib, thiab cov solidified ib feem yog ejected.
Tsim pwm tsim thiab ejection mechanisms tiv thaiv kom txhob lo los yog deformation thaum tso tawm.
Txheej txheem tswj
Cov tsis tseem ceeb xws li qhov kub thiab txias, siab, thiab lub voj voog lub sij hawm yuav tsum tau ua tib zoo saib xyuas.
Kev tswj xyuas qhov tseeb ua kom cov khoom siv tau zoo, qhov ruaj khov, thiab cov khoom zoo ib yam.
Cov txiaj ntsig ntawm HDPE Txhaj Moulding
Nqi Efficiency
HDPE yog ib qho ntawm cov yas siv ntau tshaj plaws hauv kev txhaj tshuaj molding vim nws pheej yig thiab lub sij hawm ceev ceev (20-60 vib nas this). Piv rau cov yas tshwj xeeb thiab cov khoom sib xyaw polymer, HDPE txo cov nqi tsim khoom tag nrho thaum tswj kom zoo ib yam. Qhov no ua rau nws zoo tagnrho rau siab - ntim khiav (10,000+ units), pab cov tuam txhab txo cov nuj nqis yam tsis muaj kev cuam tshuam kev ua haujlwm.
Durability thiab muaj zog
Nrog lub zog tensile siab (20-40 MPa) thiab kev cuam tshuam zoo heev, HDPE qhov chaw tuaj yeem tiv taus kev ua haujlwm hnyav. Los ntawm cov tso tsheb hlau luam rau cov khoom siv hauv tsheb, HDPE xa mus ntev - kav ntev ntev - yog ib qho ntawm cov laj thawj tseem ceeb uas nws tau txais kev pom zoo hauv cov ntawv thov.
Tshuaj tiv thaiv
HDPE tiv taus cov kua qaub, cov hauv paus, thiab cov kuab tshuaj, ua rau nws yog cov khoom siv zoo heev rau cov thawv ntim, cov kav dej, thiab lwm yam khoom siv hauv tshuaj lom neeg - hnyav hnyav. Cov cuab yeej no ua kom muaj kev nyab xeeb, kev ntseeg siab, thiab kev pab lub neej ntev.
Lub teeb
Vim nws qhov ntom ntom (0.94-0.97 g / cm³), HDPE tsim cov khoom sib sib zog nqus pwm. Qhov no pab txo cov nqi thauj khoom thiab kev siv cov khoom siv, tshwj xeeb tshaj yog muaj txiaj ntsig zoo hauv kev lag luam xws li tsheb, tsheb thauj mus los, thiab ntim khoom.
Kev rov ua dua tshiab
HDPE yog 100% recyclable, txhawb kev tsim khoom ruaj khov thiab ua raws li cov phiaj xwm kev lag luam ncig. Nws eco-profile tus phooj ywg ua rau nws yog ib qho kev xaiv zoo nkauj rau cov tuam txhab ua ntej lub luag haujlwm ib puag ncig.
Versatility hauv Design
HDPE txhaj molding tso cai rau cov geometry nyuaj, cov phab ntsa nyias, thiab cov haujlwm ua haujlwm xws li pob khawm thiab xov. Tsis tas li ntawd, nws sib raug zoo nrog ntau yam txheej txheem molding-xws li txhaj tshuaj, tshuab, thiab extrusion- ntxiv nthuav nws qhov yooj yim tsim.
Huab cua thiab UV Resistance
Thaum ua ke nrog UV stabilizers, HDPE tiv taus huab cua, tshav ntuj, thiab sab nraum zoov degradation. Qhov no ua rau nws zoo tagnrho rau kev siv sab nraum zoov xws li cov kav dej, cov khoom siv hauv chaw ua si, thiab cov khoom ua si.
Ua raws li FDA
Khoom noj khoom haus- qib HDPE ua tau raws li FDA cov qauv, ua kom muaj kev nyab xeeb hauv kev ntim khoom noj, khoom siv kho mob, thiab lwm yam kev noj qab haus huv- hais txog daim ntawv thov. Qhov kev ua raws cai no txhim kho nws tus nqi hauv kev lag luam uas yuav tsum tau muaj kev pom zoo nruj heev.
