Cov ntsiab lus hauv qab no yuav tsum tau them sai sai rau thaum tsim cov tuag castings nrog inserts:
(1) Ntxig thiab tuag castings yuav tsum txuas ruaj khov. Txhawm rau tiv thaiv qhov ntxig los ntawm kev txav, tig lossis rub tawm hauv qhov tuag casting thaum nws ntxhov siab, qhov saum npoo ntawm qhov ntxig ntxig rau hauv qhov tuag casting yog tsim los rau hauv qhov tsim nyog concave convex zoo, thiab feem ntau siv txoj kev. yog knurling, knurling, grooving, milling thiab flattening.
(2) Thaum muab tso rau hauv cov pwm, nws yuav tsum muaj qhov chaw txhim khu kev qha thiab tsim nyog kam rau ua nrog pwm.
(3) Lub thickness ntawm cov hlau txheej nyob ib ncig ntawm lub insert yuav tsum tsis txhob nyias heev, thiaj li mus txhim kho lub wrapping quab yuam ntawm lub casting ntawm lub insert thiab tiv thaiv cov kab nrib pleb nyob rau hauv cov hlau txheej. Lub thickness ntawm cov hlau txheej tuaj yeem xaiv tau raws li txoj kab uas hla ntawm cov ntxig
(4) Ib feem ntawm qhov ntxig ntxig rau hauv qhov casting yuav tsum tsis txhob muaj cov kaum ntse ntse los tiv thaiv qhov tuag casting los ntawm kev tawg ntawm cov kaum ntse ntse.
(5) Yuav tsum tsis muaj electrochemical corrosion ntawm qhov ntxig thiab tuag casting substrate, thiab sab nrauv ntawm qhov ntxig tuaj yeem coated yog tias tsim nyog.
(6) Kev kho cua sov yuav tsum raug zam rau kev tuag castings nrog cov ntxig ntxig, kom tsis txhob muaj qhov sib txawv ntawm qhov sib txawv vim qhov sib txawv thermal expansion coefficients ntawm ob cov ntaub ntawv, uas ua rau looseness ntawm inserts nyob rau hauv tuag castings.
