7. AdvantageWe have first-rate production line, the most professional staff, and the
advanced
Equipment and inspection method for casting.
Super quality, competitive priceand strict delivery time.
a. We adopt the advanced smelting and casting technology to
guarantee the reliability, accuracy and homogeny of the chemical
components of materials. It makes sure the mechanical property of
steel sleeve when adopted the advanced heating processing
technology. Machining uses the special steel sleeve process tools
and reasonable process technology to make sure the coaxiality,
cylindricity, symmetry and dynamic balance of the steel sleeve.
Specific tolerance and form and location tolerance are strictly
controlled over the scope of drawing requirements.
Manufacturing technique of sleeve:
molten steel → centrifugal casting → molding workblank →
normalizing → temper →rough finish hardening and tempering → finish
machining inner hole →process the end face , conical and excircle
inspect based on inner hole → strike trademark → issue the
certificate → pack wrap
b. Temperature resistance of steel sleeve: MAX 540°C
c. The steel sleeve proceeds the balance test on the premise of
satisfying the drawing, the value is not more than15 g.
d. The form and location tolerance are carried out according to the drawing.
e. The hardening and tempering of cast sleeve: hb240~280, tempering technology: water quenching and oil cooling, well type hardening
and tempering
