1 tug los tsis xws luag
Tej yam twg puas tshwm saum nplaim die-castings, mas feem ntau yuav pom visually. Tsawg nrum thiab kaum tsev los tsis xws luag xws li tsis sau ceev hais txog; Txaus tias yuav tshwm sim ib ncig koj lub rooj vag, nyob sab nraum cov nyhuv laminar, thiab tuag kub; Matt deg, txias nqawm kho raws los mas yog kub yaj yog ib yam nkaus thiab tsawg, prone rau yis kom deb ntawm lub rooj vag loj thiab ob tug alloy interchanges txaus, thaum hloov lub rooj vag los yog yuav muab eliminated muaj dej kub.
Tswj tej tsis xws luag, ntxiv rau qhov gating zog tsim, tseem ceeb kom paub xaiv txoj kev casting tsim nyog tuag. Tsis tshua muaj pa kub siab ceev casting tuag casting txoj kev cai lij choj, siab ceev tuag casting txujci thiab uas tsis muaj kev kub ceev uas tsis muaj tuag casting txujci. Casting tsis kub yuav txo qhov kub ntawm cov kua alloys thiab lawv yaig, high-speed shooting zoo nto yuav yog tau, thaum muaj kub high-speed tuag-cam khwb cia tooj liab alloys, zus tau tej cov txhuas nyias-walled alloy kom zoo dua yog cuab kev; Phab ntsa thickness ntawm txoj kev tuag casting mas siv kub tsis tig phiv feem, yooj yim sau thiab tub ntxhais ntawm casting, kub muaj peevxwm yuav ua raws li daim ntawv yuav tsum tuag, sab sau ceev yuav txo tau tej yam txaus rau cov tub ntxhais tiam sis; Contradiction yog cov stomata uas tuab-walled xeem thiab siab noj, siv los kub qes qes-ceev tuag cam khwb cia.
2 pwm tso los tsis xws luag
Ib hom, deformation yog ib qho pwm tso los tsis xws luag. Stripping nqes hav thaum lub alloy txaus kom ua rau qhov chaw uas kab noj hniav so vim overheating, thiab tso cov-so, deformation, kab nrib pleb thiab puas lwm yam, yog launched los ntawm kev taw qhia txog cov chaw hauj lwm uas sis tsis ncaj, kub alloy hydraulic kev kub siab casting pwm tim lwm ntev. Tom qab stripping qhov pom tias kev raug mob rau ntawm lub casting deg thiab txawm deformed, koj yuav tsum tau ua lub siab casting pwm xub ciab txheej qaij, los yog. Thiaj li yuav tswj tau kho raws, tsuas yog los xyuas kom lub community launch sector uas niaj hnub zoo txog tej hlab los community launch tis li, lub sijhawm ntawm lub rooj vag tsim kuj fa tshwj xeeb cov alloy kua tsev rau hauv cov kab noj hniav ntawm cov kev qhia, li no sim ua kom tsis txhob molten alloy txaus muaj feem nrog tus tub ntxhais, thaum tsim tuag casting txheej txheem tsis thiab ib casting ntev ntev me ntsis.
3 tsis xws luag blowhole
Blowhole los tsis xws luag yog hom tshaj ntawm casting tsis xws luag seem nyias-walled rau tus npuas rau lub deg thiab pom micro-qhov mas thaum koj tuag castings polishing, txheej, yuav ua tau foaming ntawm txheej; Nyob tuab-walled feem rau ntawm lub qhov toj, txha loj heev, mas shrinkage yuav mus. Porosity los tsis xws luag rau ntau yam, co foremost yog tus sau ntawm lub tso tseem impeded thiab qhwv. Txoj kev los tswj thiab tiv thaiv hom flaws, mas yuav kom tsim nyog pa hauv kev die-casting, ntseeg nkaws, xa los yog txo lub tsev thaum sau muaj kab noj hniav alloy crashing kua. Yuav tsum uas sau cov ntsiab lus nram qab no: (1) tam sim no hauv designs featured Ingate tsim qauv ntawm cov ntaub ntawv ntau heev, tiam sis lub rooj vag seem yog qhov tseem ceeb approximate uas yog payment. Thaum lub sij hawm ntawm rooj vag puab tsim, yuav tsum tawm mus kho hom raws li cov kev kawm txawj xwb, yog li ntawd, yog hloov mus sib tom qab. Kev lawm hais tias lub rooj vag loj yog tus loj, kom kis tau tus mob hauv siab, yooj yim rau cov ntaub ntawv raug mob los ntawm cov kev txhaj tshuaj ceev haum. (2) xyuas cov kab txeej kabke uas tuag casting mould thiab du. (3) xaiv yuav tuag casting tsis taug txoj cai, hauv cov premise uas koj ntsib tus thawj txoj cai, yuav tsum txhob txo casting kub, txhaj ceev, txhaj siab. (4) tuag casting thickness ntawm tus txheej yuav mob loj tsawv, teeb thickness.
4 kub zoo tsis xws luag
Kub los tsis xws luag feem ntau ua ib zoo nrog muaj quas ntawm casting siv lead ua loj loj, hlau tawv me ntsis thiab nonmetallic zog ntxiv zog. Rau crystalline tsis xws luag, Al-Si alloy yog hloov txoj kev yuav siv tau, thiab lwm lub alloys no mas tswj alloy melting kub thiab tuav lub sij hawm. Qhov uas hnov xov taw tes yog tsis allergic ntawm alloys, khoom siv, xws li hlau, uas tsis yog-nws yog xim hlau zog ntxiv no mas cov xim muaj hlau siv khoom xuab zeb, qhov cub xob. Tswj kho raws yam no mas los xyuas kom meej tias muaj pes tsawg leeg raw khoom muas kis nruj me ntsis tswj cov cai thaum smelting txheej txheem, tswj cov tshuaj muaj pes tsawg leeg hloov, thiab has cov tswj kev siv khoom, tov impurities yog nruj me ntsis txwv.
