Cov txheej txheem txhaj tshuaj molding yog tsim rau huab hwm coj ntau ntawm cov khoom zoo dua thiab cov khoom siv ntau dua. Cov txheej txheem txhaj tshuaj molding feem ntau nyob ntawm tus qauv tsim thiab cov khoom siv hauv kev tsim khoom. Yog li ntawd, cov tuam txhab nrhiav cov txheej txheem yooj yim dua los tsim cov khoom zoo dua ntawm tus nqi qis tig mus rau txhuas txhaj tshuaj molding.
Ib txwmaluminium tuag-casting cov khoomkuj tuaj yeem tsim tau. Txawm li cas los xij, lawv tseem muaj ntau yam tsis txaus, cov khoom kam rau ua yog qhov loj, thiab qee qhov yuav tsum tau ua tiav theem nrab thiab qib theem. Vim nws yog ib qho nyuaj rau lawv los lav kev tsim khoom sai. Peb yuav tham txog qhov zoo, qhov tsis zoo, thiab cov yam ntxwv ntawm txhuas txhaj tshuaj molding.
Kev txhaj tshuaj yog dab tsipwm aluminium tom qab?
Nrog rau kev nce qib ntawm kev sib raug zoo thiab thev naus laus zis thiab kev loj hlob ntawm kev lag luam thoob ntiaj teb, lubhmoov metallurgy kev lag luamtxhim kho sai vim nws muaj ntau yam zoo, thiab nws cov cuab yeej siv tau dav siv hauv kev ua tub rog, kev thauj mus los, tshuab, hluav taws xob, aerospace, aviation, thiab lwm yam.
MIM (hlau txhaj tshuaj molding)kev pub mis yog lub hauv paus ntawm cov txheej txheem ntawm cov hlau txhaj tshuaj molding khoom npaj, uas yog cov hmoov hlau thiab molding tus neeg sawv cev raws li ib qho kev faib ua feem ntawm qhov kub thiab txias, nyob rau hauv lub tshuab sib tov rau ib lub sij hawm kub sib tov. Tom qab ntawd los ntawm cov ntsia hlau extrusion txiav granulation, rau hauv kev txhaj tshuaj molding pub.
Txawm hais tias cov khoom siv aluminium muaj qhov ntom ntom, nws cov khoom muaj zog yog qhov siab, uas yog nyob ze lossis tshaj ntawm cov hlau zoo. Nws muaj zog plasticity, zoo thermal conductivity, corrosion kuj, thiab thermal conductivity. Qee cov aluminium alloys tuaj yeem tau txais cov khoom zoo thiab cov khoom siv lub cev los ntawm kev kho cua sov, thiab tuaj yeem tau txais kev tiv thaiv corrosion zoo dua los ntawm anodizing.
Vim hais tias ntawm cov tsoos aluminium alloy qhov chaw tsim cov txheej txheem, tsis tshua muaj kev ua tau zoo, kev ua haujlwm nyuaj, thiab cov qauv kev ua haujlwm ntawm cov khoom lag luam tsis tuaj yeem tawm, tau ua tiav tsis tuaj yeem ua tau raws li qhov xav tau ntawm txoj kev loj hlob sai ntawm kev lag luam niaj hnub kev lag luam.
Yog li ntawd, nws yog ib qho tsim nyog los muab ib qho txhuas mim hlau txhaj tshuaj molding pub haum rau covhlau txhaj molding txheej txheem.
Dab tsi yog Hlau txhaj tshuaj molding txhuas siv tshuab siv cov ntsiab lus?
Raws li qhov no, nws yog ib qho tsim nyog yuav tsum muab cov txhuas txhaj tshuaj molding pub, txhuas txhaj tshuaj molding qhov chaw, thiab cov txheej txheem kev npaj, suav nrog aluminium alloy txhaj tshuaj molding pub, txhuas txhaj tshuaj molding pub kev npaj, aluminium alloy txhaj molding qhov chaw, thiab txhuas txhaj tshuaj molding qhov chaw npaj txoj kev.

Ib txoj kev npaj rau kev txhaj tshuaj molding aluminiumsuav nrog cov kauj ruam hauv qab no: suav nrog ib txoj hauv kev npaj kev txhaj tshuaj molding pub ntawm aluminium alloy raws li tau piav qhia saum toj no thiab, tom qab txiav thiab pelleting pub, cov kauj ruam: sib sau, degreasing, thiab sintering.
Qhov kev tsim kho muaj feem xyuam rau ib qho txhuas txhaj tshuaj molding ib feem uas tau npaj los ntawm txoj kev npaj ib qho ntawm cov aluminium alloy txhaj tshuaj molding qhov chaw uas tau hais los saum no.
Qhov saum toj no-hais aluminium txhaj tshuaj molding feedstock, aluminium alloy txhaj tshuaj molding qhov chaw, thiab cov txheej txheem kev npaj yuav siv tau rau zus tau tej cov aluminium alloy khoom nrog complex qauv, uas hloov cov shortcomings ntawm tsoos aluminium alloy ua nyuaj, ntev ua lub voj voog thiab siab ua nqi, zoo heev txo cov tsim thiab ua nqi ntawm complex aluminium alloy qhov chaw, thiab innovates hom ntau lawm ntawm tag nrho cov txhuas alloy kev lag luam. Nws tau nce qib ntawm kev tsim kho thev naus laus zis thiab kev tsim khoom hauv kev tsim khoom hauv tsev. Ntxiv mus, los ntawm cov txheej txheem tshiab, kev npaj tshiab thiab ua cov txheej txheem, qhov zoo ntawm qhov tau txais aluminium alloy txhaj tshuaj molding qhov chaw zoo heev, tshwj xeeb tshaj yog tsim rau cov khoom loj, kom txo tau tus nqi thiab txhim kho kev ua haujlwm ntawm kev tsim cov txhuas molding qhov chaw.
Dab tsi yog qhov zoo ntawm aluminium hlau txhaj tshuaj molding pwm?
· Nqi
Thaum nws los txog rau kev txhaj tshuaj pwm, txhuas txhaj tshuaj pwm yog pheej yig dua li cov hlau txhaj tshuaj pwm. Piv txwv tias tag nrho lwm cov kev mob sib npaug, cov pwm ua los ntawm txhuas tuaj yeem rov qab tau cov pwm peev nyiaj tau sai heev.
· Lub sij hawm tsim khoom
Aluminium pwm ua kom cov khoom lag luam sai dua. Los ntawm kev tsim pwm mus rau cov khoom tiav lawm, steel txhaj molding yuav siv sij hawm 1-2 lub hlis. Txawm li cas los xij, nrog txhuas txhaj tshuaj pwm, kev tsim cov pwm, cov qauv thiab cov khoom tiav siv sijhawm 7-14 hnub xwb.
· Siv tau rau cov khoom tsawg
Aluminium yas txhaj pwm yog tus nqi ntau dua rau kev ua cov khoom hauv cov khoom me me. Qhov no yog vim tus nqi pib nws muaj peev xwm txo tau, thaum tsuas yog ua ntau txhiab qhov txhim khu kev qha.
· Lub sijhawm sib tsoo
Steel pwm tsis dissipate tshav kub sai li aluminium prototype pwm. Yog li ntawd, lawv tuaj yeem ua kom sov thiab txias sai dua. Hauv kev txhaj tshuaj molding txheej txheem, lub sijhawm txias txias rau lub voj voog ntawm tag nrho cov txheej txheem molding. Yog li ntawd, xaiv txoj kev tsim aluminium tuaj yeem ua rau lub sijhawm luv luv thiab yog li ua kom cov khoom lag luam nrawm.
· Boutique
Cov cua kub tsis sib xws thiab cua txias yog ib qho ua rau muaj qhov tsis xws luag xws li cov cim dab dej, voids thiab hlawv nti. Qhov zoo tshaj plaws tshav kub dissipation ntawm aluminium pwm tso cai rau cov pwm yuav tsum tau rhuab thiab txias sai sai thiab tusyees, txo tus naj npawb ntawm cov khoom puas thiab seem.
· Yooj yim Kho thiab Retrofits
Lub hardness ntawm steel yog siab heev, yog li lub sij hawm kho ntawm deformed los yog puas steel pwm yog ntev thiab kho tus nqi siab, uas nyob rau hauv lem cuam tshuam lub sij hawm ntawm cov khoom. Txawm li cas los xij, txhuas yas txhaj tshuaj pwm yog tsim los ntawm cov ntaub ntawv softer, thiab cov yam ntxwv no ua rau kev kho thiab hloov tau yooj yim yog tias muaj teeb meem nrog cov txhuas txhaj tshuaj pwm.
