Hauv kev lag luam niaj hnub no, cov txheej txheem molding rau cov khoom yas muaj ntau yam thiab ntau yam. Cov tuam txhab feem ntau xaiv txoj kev tsim molding zoo tshaj plaws raws li cov khoom siv, cov khoom siv, thiab ntim ntau lawm. Ntxiv nrog rau cov txheej txheem thermoforming ib txwm muaj uas peb paub, kev nce qib siab ntawm -kev tsim khoom kawg tau ua rau kev tsim cov khoom siv hluav taws xob zoo tshaj plaws - tshwj xeeb CNC machining- piv txwv tias muaj lub luag haujlwm tseem ceeb hauv kev ua cov khoom yas yas. Cov ntu hauv qab no muab cov txheej txheem txheej txheem ntawm cov txheej txheem ua cov yas thiab lawv cov yam ntxwv tseem ceeb.
Tshuab moulding yog cov cuab yeej tseem ceeb rau kev tsim cov khoom yas hollow; tseeb tiag, tshaj li ib -feem peb ntawm tag nrho HDPE (High-Density Polyethylene) cov khoom raug tsim los ntawm txoj kev no. Cov txheej txheem no tsim cov kev cai tshwj xeeb ntawm cov khoom hais txog lub zog yaj, ib puag ncig kev ntxhov siab tawg tsis kam (ESCR), thiab toughness. Extrusion, conversely, yog ib tug heev npaum, tas mus li ntau lawm txheej txheem lug siv nyob rau hauv kev tsim cov kav dej, nplooj ntawv, thiab zaj duab xis. Cov ntaub ntawv tsim los rau extrusion feem ntau muaj qhov qis Melt Index (MI) kom ntseeg tau tias muaj zog yaj txaus; Nyob rau tib lub sijhawm, kev nthuav dav Molecular Weight Distribution (MWD) pab txhawb kev tsim khoom nrawm dua, txo qhov tuag- lub taub hau siab, thiab txo qhov nyiam ntawm cov pob txha tawg. Txawm hais tias los ntawm tshuab moulding los yog extrusion, cov tswv yim no yog cov txheej txheem classic rau kev tsim khoom loj ntawm cov khoom lag luam yas.
Txoj kev sib hloov molding feem ntau cuam tshuam nrog melting thiab tsim cov hmoov yas hauv lub voj voog thermal; nws nquag ua haujlwm nyob rau hauv kev tsim cov tank loj lossis cov khoom siv sab nraum zoov. Cov txheej txheem no feem ntau siv dav dav -cov hom phiaj qib ntawm MDPE lossis HDPE, uas muaj qhov ntom ntom ntawm 0.935 txog 0.945 g / cc thiab nqaim molecular hnyav faib, kom ntseeg tau tias cov khoom tiav tiav muaj kev cuam tshuam lub zog thiab tiv thaiv warping. Hauv qhov sib piv, kev txhaj tshuaj molding yog qhov zoo dua rau kev tsim cov ntim me me, zoo li cov tshuaj vials thiab tshuaj zawv plaub hau. Ib qho txiaj ntsig tseem ceeb ntawm kev txhaj tshuaj molding yog tias cov fwj uas tau tshwm sim tau raug tshem tawm ntawm -flashed (trimmed), tshem tawm qhov xav tau ntawm cov ncej tedious - kev ua kom huv si feem ntau xav tau hauv tshuab molding. Rau cov khoom uas nto tiav yog ib qho tseem ceeb yuav tsum tau, cov qib tshwj xeeb nrog tailored molecular hnyav distributions feem ntau xaiv los tsim ntau yam kev cai yas qhov chaw.
Kev ua cov PE zaj duab xis feem ntau siv cov txheej txheem tshuab tshuab extrusion lossis tiaj tus-txoj kev extrusion; ntawm cov no, zaj duab xis- qib HDPE cov ntaub ntawv tau dav siv vim lawv lub zog tensile zoo dua thiab cov khoom thaiv. Casting yog txheej txheem feem ntau siv los tsim cov khoom hluav taws xob rwb thaiv tsev, lub zog, pulleys, thiab cov vaj huam sib luag zoo nkauj; nws leverages lub siab fluidity thiab tsawg shrinkage yam ntxwv ntawm cov kua resin sib tov kom tiav tsim nyob rau hauv atmospheric siab los yog tsawg kawg nkaus siab. Kev txhais dav dav, "moulding" yog ib lo lus sib sau xa mus rau txhua tus txheej txheem uas cov ntaub ntawv yas tau zoo li tus qauv siv pwm, nyob rau hauv cov xwm txheej uas muaj cua sov thiab siab. Cov txheej txheem molding ntau yam no tau nthuav dav dav ntawm cov txheej txheem kev xaiv muaj rau cov qauv yas thiab cov khoom me me -batch, yog li txaus siab rau qhov zoo nkauj thiab kev ua haujlwm ntawm ntau yam kev lag luam.
Raws li kev xav tau thoob plaws ntau qhov kev lag luam tau hloov zuj zus thiab siv zog, CNC yas machining txheej txheem tau tshwm sim los ua kom tau raws li cov kev cov nyom tshiab no. Tsis zoo li cov txheej txheem thermoforming, CNC machining yog cov txheej txheem tsim khoom; nws yog qhov zoo tshwj xeeb tshaj yog- haum rau kev ua cov khoom tshwj xeeb engineering yas uas muaj cov tawv tawv siab thiab ntom ntom- xws li Teflon (PTFE), Polyacetal (POM), thiab Polyether Ether Ketone (PEEK). Txhawm rau kom ua raws li cov kev xav tau ntawm cov khoom siv siab no, feem ntau yuav tsum tau siv cov cuab yeej tshwj xeeb uas suav nrog siab - steel cutters, carbide cutters, cov cuab yeej tig, thiab ntau hom ntawv milling cutters. Los ntawm cov kev pabcuam yas CNC machining, siab - precision manufacturing ntawm complex structural Cheebtsam yuav ua tau tiav, zoo bridging qhov tsis muaj nyob rau hauv ib txwm pwm-raws li manufacturing hais txog prototyping thiab me me -batch customization.
Nyob rau hauv lub realm ntawm CNC machining, nyias txiav cov tswv yim yog ua hauj lwm los hais txog cov cim geometric nta ntawm txawv qhov chaw. Yas CNC Milling feem ntau yog siv rau machining tiaj tus, grooves, thiab complex peb -dimensional contours, whereas CNC tig tsom tshwj xeeb rau machining lub sab nraud diameters thiab sab hauv bores ntawm rotational qhov chaw, ua kom muaj txiaj ntsim ntau lawm ntawm high -precision tig Cheebtsam. Tsis tas li ntawd, cov txheej txheem yas CNC txiav yog lub luag haujlwm rau kev txiav cov ntaub ntawv raw mus rau qhov ntev los yog ua qhov kev nplua -tuning ntawm cov txheej txheem. Kev txiav txim siab ua ke ntawm cov txheej txheem ntau yam no yog qhov tseem ceeb rau kev ua kom zoo ntawm cov khoom kawg.
Tsis yog tag nrho cov yas yog tsim rau CNC machining; Yog li ntawd, kev xaiv cov khoom yuav tsum tau ua tib zoo xav txog yam xws li hardness, kub deflection kub, thiab mechanical zog. Cov ntaub ntawv yas uas haum rau CNC machining muaj xws li Polycarbonate (PC), Nylon (PA), Acrylic (PMMA), raws li tau hais dhau los PEEK thiab POM. Piv txwv li, thaum ua Polycarbonate CNC Machining, txiav tsis yuav tsum nruj me ntsis tswj kom tsis txhob muaj cov khoom tawg. High- zoo engineering plastics tsis tsuas yog ua kom muaj kev ruaj ntseg thaum lub sij hawm machining txheej txheem tab sis kuj tso cai rau cov khoom tiav nrog cov khoom zoo dua qub.
Txhawm rau kom tau txais qhov zoo - CNC qhov chaw ua los ntawm engineering plastics, xaiv cov ntaub ntawv thiab cov txheej txheem yog qhov tseem ceeb; Txawm li cas los xij, kev xaiv ntawm cov cuab yeej txiav thiab kev teeb tsa ntawm kev txiav tsis yog qhov tseem ceeb sib npaug. Vim yog cov thermal conductivity tsis zoo ntawm cov yas-thiab lawv txoj kev nyiam ua raws li cov cuab yeej txiav-machining feem ntau xav tau kev siv cov cuab yeej ntse carbide, ua ke nrog cov txheej txheem txias kom tsim nyog. Txawm hais tias koom nrog CNC milling lossis tig cov ntaub ntawv yas, cov txheej txheem meej tswj tau zoo tiv thaiv qhov tsis xws li burrs thiab deformation, yog li ua kom cov khoom xa tuaj ntawm cov khoom siv precision uas nruj me ntsis ua raws li cov qauv tsim.
Thaum lub sijhawm txhim kho cov khoom lag luam, cov tuam txhab feem ntau yuav tsum tau ua kom tiav cov qauv tsim ua haujlwm sai; qhov no yog qhov kev cai CNC yas prototypes ua lub luag haujlwm tseem ceeb. Los ntawm CNC machining, prototypes uas ze ze tsom iav qhov tsos thiab kev ua haujlwm ntawm huab hwm coj- cov khoom tsim tuaj yeem tsim tau - ua ntej pwm fabrication - ntawm tus nqi qis dua thiab nrog ceev tshwj xeeb. Cov qauv hloov tau yooj yim thiab muaj txiaj ntsig zoo ntawm cov kev pabcuam yas machining ua rau txo qis cov khoom lag luam kev loj hlob, ua rau cov tuam txhab tau txais kev sib tw hauv kev lag luam sib tw hnyav.
