{{03. Mould Kev Tswj Xyuas: Precision Drives Cov Khoom Uas Tsis Zoo
China's mold industry exhibits stark quality differences: large manufacturers (e.g., Dongguan Yixin, Suzhou Baoma) use slow wire EDM (precision ±0.005mm) and vacuum heat treatment (HRC60±2), achieving mold life up to 800,000–1,000,000 cycles. Small workshops, however, often use low-grade materials (e.g., T10A instead of Cr12MoV) and shortcut processes, leading to thread pitch diameter deviations (e.g., M8 nuts exceeding the 6.912mm ±0.05mm standard) and hexagon diagonal errors (>0 {{. 36 hli ib gb).Tswj raws txoj kev cai:

5. galvanizing txheej txheem: zoo-tuning rau qhov kev ua tau zoo
Kev tswj tsis raug cai ntawm kub-dip galvanizing tsis ua rau cov tsis txaus ntseeg:

Tsis muaj tseeb flux sib tov (ZNCL2<50g/L): Txo cov txheej adhesion, ua rau delamination .
Cov Txheej Txheem Qauv:
Kev Kho Mob Ua Ntej: Acid pickling + ultrasonic ntxuav (10-15 feeb los tshem tawm cov oxides yam tsis muaj tshaj-corrosion).
Galvanizing: Saib Zinc Da Dej ntawm 445-455 degree, nrog ntsw lub sijhawm kho los ntawmtxiv ntooThickness (8-10S rau M6-M10, 12-15S rau M12-M24) {{{} Thaum rho tawm 45℃{}}
