Nqus Castings

Nqus Casting (Neegative Pressure Sealed Casting, Reduced Pressure Casting lossis V Process Casting) siv cov xuab zeb qhuav thiab tsis zoo los tsim cov pwm pwm. Lub tshuab nqus tsev tsis zoo siab casting yog ib hom ntawm cov xuab zeb qhuav qhuav thiab yuav tsum tau siv cov khoom siv cua tshem tawm kom tshem tawm cov huab cua hauv cov pwm pwm, thiab tom qab ntawd siv qhov sib txawv ntawm qhov sib txawv ntawm cov pwm sab hauv thiab sab nraud ntawm cov pwm los npog cov yas zaj duab xis rhuab ntawm lub tshuab nqus tsev. cov qauv thiab cov qauv. Lub casting pwm yuav muaj zog txaus los tiv thaiv cov hlau molten thaum lub sij hawm casting. Tom qab tau txais lub tshuab nqus tsev casting pwm, sau lub thawv xuab zeb nrog cov xuab zeb qhuav yam tsis muaj binder, thiab tom qab ntawd muab cov xuab zeb ntim rau saum npoo nrog cov yas zaj duab xis, ua raws li lub tshuab nqus tsev kom cov xuab zeb ruaj khov thiab nruj. Tom qab ntawd, tshem tawm cov pwm, muab cov xuab zeb cores, kaw lub pwm kom txhua yam npaj txhij rau pouring. Thaum kawg, lub casting yog tau tom qab lub molten hlau yog txias thiab solidified.
