Poob ua npuas ncauj casting (tseem hu ua cov pwm tiag tiag) yog ua los ntawm cov yas ua npuas ncauj (EPS, STMMA lossis EPMMA) cov khoom siv polymer rau hauv pwm tiag tiag nrog cov qauv zoo ib yam thiab loj raws li cov khoom yuav tsum tau tsim thiab cam khwb cia, thiab yog dip-coated. nrog refractory txheej (muaj zog), du thiab breathable) thiab qhuav, nws yog faus rau hauv qhuav quartz xuab zeb thiab raug rau peb-dimensional kev co qauv. Cov hlau molten yog poured rau hauv molding xuab zeb lub thawv nyob rau hauv qhov tsis zoo siab, yog li ntawd cov khoom siv polymer yog rhuab thiab vaporized, thiab ces muab rho tawm. Ib txoj kev tshiab casting uas siv cov hlau ua kua los hloov cov txheej txheem pwm ib zaug ua tom qab txias thiab khov kho los tsim cov castings. Poob ua npuas ncauj casting muaj cov yam ntxwv hauv qab no: 1. Castings yog qhov zoo thiab tus nqi qis; 2. Cov ntaub ntawv tsis txwv thiab haum rau txhua qhov ntau thiab tsawg; 3. High precision, du nto, tsawg tu, thiab tsawg machining; 4. Cov teeb meem sab hauv raug txo qis heev thiab cov qauv ntawm cov casting zoo tuaj. ntom ntom; 5. Nws tuaj yeem paub qhov loj thiab ntau lawm; 6. Nws yog tsim rau loj ntau lawm castings ntawm tib castings; 7. Nws yog qhov tsim nyog rau kev ua haujlwm ntawm phau ntawv thiab kev sib dhos ua ke ntawm cov kab ntau lawm thiab kev tswj xyuas kev ua haujlwm; 8. Cov xwm txheej ntawm cov kab ntau lawm ua tau raws li qhov yuav tsum tau muaj ntawm kev tiv thaiv ib puag ncig kev ua haujlwm. ; 9. Nws tuaj yeem txhim kho qhov chaw ua haujlwm thiab kev tsim khoom ntawm cov kab ntau lawm, txo kev siv zog, thiab txo kev siv zog.
Tus tsim yog hloov tau thiab muab kev ywj pheej txaus rau kev tsim cov qauv tsim. High complex castings tuaj yeem nrum los ntawm kev sib xyaw ua npuas ncauj pwm.
Txo cov peev txheej thiab cov nqi tsim khoom, txo qhov hnyav ntawm cov khoom seem casting, thiab muaj cov nyiaj ua haujlwm me me. (1) Batch kom muaj nuj nqis ntawm castings (2) Casting khoom (3) Casting loj (4) Casting qauv
Tsis muaj cov xuab zeb hauv cov tsoos casting, yog li yuav tsis muaj qhov tsis sib xws ntawm phab ntsa ntawm cov hlau castings tshwm sim los ntawm qhov tsis raug cov xuab zeb core loj los yog qhov tsis raug cov tub ntxhais txoj hauj lwm hauv tsoos xuab zeb casting.
. Castings muaj siab precision. Poob ua npuas ncauj casting yog txheej txheem tshiab uas yuav luag tsis muaj npoo thiab raug molding. Cov txheej txheem no tsis xav tau pwm noj, tsis muaj qhov sib cais, thiab tsis muaj cov xuab zeb, yog li cov castings tsis muaj flash, burrs, thiab cov kaum sab xis, thiab Dimensional yuam kev tshwm sim los ntawm kev sib xyaw ua ke raug txo. Qhov nto roughness ntawm cov castings tuaj yeem ncav cuag Ra3.2 txog 12.5μm; qhov tseeb qhov tseeb ntawm cov castings tuaj yeem ncav cuag CT7 txog 9; qhov nyiaj pub rau machining yog 1.5 mus rau 2 hli feem ntau, uas tuaj yeem txo tus nqi ntawm machining. Piv nrog rau cov tsoos xuab zeb casting txoj kev, nws yuav raug txo los ntawm 40% mus rau 50% ntawm machining lub sij hawm.
Kev tsim khoom huv si, tsis muaj tshuaj binders hauv cov xuab zeb molding, ua npuas ncauj plastics yog ib puag ncig tus phooj ywg ntawm qhov kub thiab txias, thiab qhov rov ua dua ntawm cov xuab zeb qub yog tshaj 95%.
