Nqus casting steel cua ntsawj ntshab iav vaj tse rau tsheb thauj khoom rau Lavxias teb sab kev lag luam nrog CNC machining thiab kev cai taillor-made cov kev pab cuam. Cam khwb cia hlau v txheej txheem castings txhais tau hais tias cov casting qhov chaw tsim los ntawmlub tshuab nqus tsev casting txheej txheemnrog cov ntaub ntawv ntawm cam khwb cia hlau.
Nqus molding casting, tseem hu ua tsis zoo siab molding txoj kev, nqus sealing molding txoj kev, los yog V txheej txheem rau luv luv. Qhov no yog ib yam tshiab ntawm lub cev qauv qauv. Txoj kev tsis zoo siab molding txoj kev siv lub siab sib txawv ntawm sab hauv thiab sab nraud ntawm cov pwm kom ceev cov xuab zeb qhuav thiab xoob xoob ua ke kom tau cov pwm nrog ib qho kev xav tau thiab muaj zog.
Qhov zoo ntawm Vacuum Casting txheej txheem
1) Lub tshuab nqus tsev castings muaj qhov tseeb qhov tseeb, cov qauv qhia meej thiab du nto.
Vim tias qhov saum npoo ntawm tus qauv yog npog nrog cov yas zaj duab xis, tsis tas yuav vibrate lossis khob thaum rub lub pwm. Lub suction thiab tsis zoo siab ua rau cov xuab zeb molding compact, thiab hardness ntawm cov xuab zeb pwm yog siab thiab uniform. Nyob rau hauv lub tshav kub ntawm molten hlau, cov kab noj hniav tsis yooj yim rau deform. Tsis tas li ntawd, qhov muaj nyob ntawm qhov tsis zoo siab yog qhov tsim nyog rau kev sau tag nrho ntawm cov hlau molten rau hauv cov qauv. Qhov nto roughness ntawm V txheej txheem castings tuaj yeem ncav cuag Ra = 25 ~ 2.5μm. Qhov siab kam rau ua theem ntawm castings tuaj yeem ncav cuag CT5 ~ CT7. Cov tsos zoo ntawm qhov tsis zoo siab castings yog qhov zoo, thiab qhov zoo ntawm sab hauv yog txhim khu kev qha.
2) Tsis muaj binders, dej thiab additives hauv cov xuab zeb molding, uas ua rau cov xuab zeb ua tau yooj yim.
3) Nws yog qhov yooj yim los ntxuav lubnqus castings. Tsawg cov pa phem raug tsim tawm thaum lub sij hawm casting txheej txheem.
4) Lub tshuab nqus tsev castings tuaj yeem siv rau ntau qhov kev lag luam. Nws tuaj yeem siv rau ib qho me me batch ntau lawm thiab ntau lawm, tshwj xeeb tshaj yog loj thiab nruab nrab castings thiab nyias-walled castings yog tsim nyog rau lub tshuab nqus tsev casting.
