Tseem yuav muaj kev txuag nyiaj los ntawm kev txo qis cov kev xav tau sib dhos, tshwj xeeb tshaj yog tias koj tsim ntau txhiab tus txawm tias ntau lab ntawm cov khoom.
Dab tsi yog cov yas siv hauv kev txhaj tshuaj molding
Cov hom yas siv ntau tshaj plaws yog high-density polyethylene (HDPE) thiab low-density polyethylene (LDPE). Polyethylene muaj ntau yam zoo xws li cov qib ductility siab, lub zog tensile zoo, muaj zog tiv thaiv, tiv thaiv kom tsis txhob ya raws, thiab rov ua dua tshiab.
Lwm yam kev txhaj tshuaj molded yas muaj xws li:
Acrylonitrile Butadiene Styrene (ABS)
Cov yas tawv tawv, qhov cuam tshuam-resistant no yog siv dav hauv kev lag luam. Nrog rau kev ua haujlwm zoo rau cov kua qaub thiab cov hauv paus, ABS kuj muaj cov nqi qis qis thiab siab ruaj khov.
Polycarbonate (PC)
Qhov no muaj zog, cuam tshuam resistant yas muaj tsawg shrinkage thiab zoo seem stability. Cov yas pob tshab uas muaj nyob rau hauv ntau qib optically ntshiab, PC tuaj yeem muab cov khoom zoo nkauj zoo nkauj thiab ua kom sov zoo.
Aliphatic Polyamides (PPA)
Muaj ntau ntau hom PPA (los yog nylons), txhua tus muaj nws qhov zoo. Feem ntau hais lus, nylons muaj lub zog siab thiab kub ua haujlwm nrog rau cov tshuaj tiv thaiv, sib nrug los ntawm cov kua qaub thiab cov hauv paus. Qee cov nylons muaj kev puas tsuaj los tiv thaiv thiab muab cov tawv tawv zoo thiab nruj nrog lub zog zoo.
Polyoxymethylene (POM)
Feem ntau hu ua acetal, cov yas no muaj siab hardness, nruj, lub zog thiab toughness. Nws kuj muaj lubricity zoo thiab tiv taus hydrocarbons thiab organic solvents. Zoo elasticity thiab slipperiness kuj muab qhov zoo rau qee qhov kev siv.
Polymethyl Methacrylate (PMMA)
PMMA, tseem hu ua acrylic, muab cov khoom kho qhov muag zoo, siab gloss thiab khawb tsis kam. Nws kuj tseem muaj qhov shrinkage tsawg thiab tsawg dab dej rau geometries nrog nyias thiab xav seem.
Polypropylene (PP)
Cov khoom siv pheej yig no ua rau muaj kev cuam tshuam loj hauv qee qib tab sis tuaj yeem ua rau qhov txias txias (hauv cov ntaub ntawv ntawm propylene homopolymer). Copolymers muaj kev tiv thaiv ntau dua rau kev cuam tshuam thaum PP kuj hnav-tiv taus, hloov tau thiab tuaj yeem muab cov elongation siab heev, nrog rau ua rau cov kua qaub thiab cov hauv paus.
Polybutylene Terephthalate (PBT)
Cov khoom hluav taws xob zoo ua rau PBT zoo tagnrho rau cov khoom siv hluav taws xob nrog rau kev siv tsheb. Lub zog sib txawv los ntawm nruab nrab mus rau siab nyob ntawm iav sau, nrog rau cov qib tsis tau ua tiav yog tawv thiab hloov tau. PBT kuj qhia tau tias roj, roj, roj thiab ntau cov kuab tshuaj, thiab nws kuj tsis nqus tsw.
Polyphenylsulfone (PPSU)
Ib qho khoom siv ruaj khov nrog lub siab tawv, kub thiab kub tsis kam, PPSU tseem tiv taus hluav taws xob tsis muaj hluav taws xob, alkalis thiab tsis muaj zog acids.

PEI (los yog Ultem) muaj qhov kub thiab txias tsis kam, nrog rau lub zog zoo, qhov ruaj khov thiab tshuaj lom neeg.
Ua-up ntawm lub tshuab txhaj tshuaj molding
Lub tshuab txhaj tshuaj molding yog tsim los ntawm cov khoom siv hopper, chim, txhaj tshuaj ram / tig ntsia hlau, cov khoom siv cua sov, cov qauv txav tau, ejectors, thiab pwm hauv pwm kab noj hniav. Feem ntau, cov tshuab ua haujlwm nyob rau hauv kab rov tav.
Lub luag haujlwm ntawm lub tshuab clamping yog qhib thiab kaw qhov tuag, thiab ejection ntawm qhov chaw. Muaj ob hom kev clamping - ib hom toggle qhia thiab ncaj-hydraulic hom, uas tso cai rau cov pwm qhib ncaj qha thiab kaw nrog lub tog raj kheej hydraulic.
Lub hopper nyob rau ntawm ib kawg ntawm lub chim, thiab hydraulic rotating ntsia hlau khiav los ntawm hluav taws xob lub cev muaj zog. Cov ntsia hlau yog tig kom yaj cov yas qhia los ntawm lub hopper. Tom qab qhov xav tau ntawm cov yas molten tau sau, cov txheej txheem txhaj tshuaj pib. Nyob rau sab nraud ntawm lub thoob, ib qho pwm txuas nrog.
Thaum cov yas molten yog ntws hauv pwm, lub tshuab txhaj tshuaj molding tswj qhov ceev ntawm cov ntsia hlau (los yog txhaj tshuaj ceev). Nws kuj tseem tswj tau lub siab raws li cov yas ntim cov kab noj hniav. Kev tswj ceev thiab kev tswj siab yog teeb tsa qhov chaw ntsia hlau thiab txhaj tshuaj siab mus txog qhov muaj nqis.
Pwm rau kev txhaj tshuaj yas muaj cov khoom siv hlau uas muaj zog heev uas tau raug tshuab ua haujlwm hauv ob halves. Cov yas molten ntws mus rau hauv pwm los ntawm cov kab noj hniav thiab sau cov kab noj hniav los ntawm kev khiav thiab rooj vag. Tom qab ntawd, cov pwm qhib tom qab cov txheej txheem txias thiab ejector pas nrig ntawm lub tshuab txhaj tshuaj molding thawb lub ejector phaj ntawm pwm kom eject moldings.
Cov txheej txheem ntawm kev txhaj tshuaj pwm yog qhov tseem ceeb txhawm rau ua haujlwm kom zoo thaum lub sijhawm txhaj tshuaj molding txheej txheem. Txawm hais tias pwm feem ntau muaj ob ntu, ib sab kab noj hniav thiab ib sab tseem ceeb, feem ntau muaj ntau ntau qhov kev ua tau zoo uas ua rau ib nrab.
Yuav luag tag nrho cov khoom siv pwm pwm uas ua haujlwm los tsim ib qho kev cai molded yog machined rau kam rau ua tsawg tshaj li +/- 0.001 "los yog 0.025mm, ib feem peb ntawm cov thickness ntawm ib. daim ntawv luam.
Dab tsi yog Txoj Kev Txhaj Tshuaj Molding
Lub voj voog ntawm kev txhaj tshuaj molding yog luv heev, feem ntau kav ntev li ntawm rau vib nas this thiab ob feeb. Cov txheej txheem muaj cov theem hauv qab no:
Clamping:Ua ntej kev txhaj tshuaj ntawm cov khoom siv yas rhuab rau hauv pwm, ob qho tib si ntawm cov pwm yuav tsum xub muab kaw kom ruaj ntseg los ntawm chav tsev clamping. Lub zog loj heev ntawm lub clamping unit thawb cov pwm ib nrab ua ke thiab khaws cov pwm kom zoo kaw thaum cov khoom txhaj tshuaj. Lub sij hawm yuav tsum tau kaw thiab clamp lub pwm yog nyob ntawm lub tshuab - cov cav tov loj nrog qhov qhib loj yuav tsum tau siv sij hawm ntau dua.
Txhaj tshuaj:Cov khoom siv yas nyoos, feem ntau yog ua cov pellets me me, tau muab tso rau hauv lub tshuab txhaj tshuaj molding thiab xa los yog augered rau pwm los ntawm chav txhaj tshuaj. Cov khoom yas heats li kub thiab compression raws li cov ntsia hlau conveys cov yas pellets los ntawm rhuab aav ntawm lub tshuab chim. Tus nqi ntawm cov yas yaj uas raug xa mus rau pem hauv ntej ntawm lub hau ntswj yog ib feem uas yuav dhau los ua qhov kawg tom qab txhaj tshuaj. Tus nqi ntawm cov khoom uas txhaj tshuaj yog hu ua txhaj tshuaj, thiab ib zaug tag nrho clamped, lub tshuab txhaj cov khoom rau hauv pwm. Lub sijhawm txhaj tshuaj tuaj yeem kwv yees los ntawm qhov ntim txhaj tshuaj, txhaj tshuaj, thiab ib feem geometry.
Cua txias:Cov yas molten hauv pwm txias sai li sai tau thaum nws ua rau kev sib cuag nrog cov pwm sab hauv. Cov txheej txheem txias ua kom cov duab thiab rigidity ntawm cov yas molded tshiab. Nws yog ib qho tseem ceeb kom nco ntsoov tias qhov shrinkage yuav tshwm sim thaum lub sij hawm txias.
Lub pwm tuaj yeem qhib tsis tau kom txog thaum lub sijhawm txias yuav tsum tau dhau mus. Lub sij hawm txias yuav tsum tau ua rau txhua qhov yas molded yog nyob ntawm cov khoom siv thermodynamic ntawm cov yas, phab ntsa thickness ntawm ib feem, thiab qhov yuav tsum tau muaj qhov ntev rau qhov tiav.
Kev tshem tawm:Thaum ib feem tau txias hauv pwm, nws tuaj yeem raug tshem tawm ntawm cov pwm los ntawm kev tso tawm. Cov yam ntxwv ntawm kev txhaj tshuaj molding tshuab thawb ib feem ntawm cov pwm siv lub zog tsim nyog rau ejection. Thaum lub sij hawm tus txheej txheem no, lub tshuab tau npaj ib tug tshiab txhaj tshuaj yas, thiab ib zaug ib feem yog tag nrho ejected, lub pwm yog npaj txhij rau ib feem tom ntej.
Tom qab txhaj tshuaj molding txheej txheem, cov ntawv thov tom qab ua tiav feem ntau yuav tsum tau ua. Qhov no yuav suav nrog cov txheej txheem thib ob rau kev kho kom zoo nkauj lossis lub hom phiaj ua haujlwm. Nrog rau kev txhaj tshuaj molding, muaj rau ntau hom kev txhaj tshuaj molding tom qab ua tiav daim ntawv thov.
