Construction Machinery Casting chi hrang hrang

Construction machinery castings tih hian in sakna hmanrua, excavator, loader, crane, bulldozer, etc.-a hman thin metal casting a kawk a, an chi hrang hrangte chu materials, casting process, leh structural functions te atanga thliar hran theih a ni.

Thupui hmanga siam:
Gray Iron Castings: HT250, HT300 ang chi, machine tool bed, gearbox housing, axle, etc.-a hman lar tak, wear resistance leh damping property tha tak nei.

Ductile Iron Castings: Key components load sang tak phur thei, crankshaft, connecting rod, gearbox housing, etc. te tan hman a ni a, grey iron aiin a chakna leh a toughness a sang zawk.

Cast Steel Castings: Structurally complex components impact load sang tak nei, crawler chassis leh boom connector te tan hman a ni.

Aluminium Castings: No-load-bearing emaw semi{2}}load-bearing component rit lo tak tak, housing, cover, hydraulic valve body, etc. atan hman a ni.

Note: Construction machinery-ah chuan iron castings (a bik takin grey iron leh ductile iron) te hian an man tlawm ber, an hnathawh theihna tha tak, leh vibration damping performance tha tak an neih avangin an tam ber a ni.

Casting Process hmangin:
Sand Casting: Green sand casting, dry sand casting, leh resin{0}}bonded quick-setting sand casting te a huam a, single-piece emaw small-batch siamna atana tha a ni construction machinery-a thil tih dan ber a ni.

Lost Foam Casting (Solid Pattern Casting): Complex thin-walled structures, engine block leh hydraulic parts te tan hman a ni a, dimensional accuracy sang tak leh surface quality tha tak a ni.

Die Casting: Aluminium leh magnesium alloy hmanga siam part te tak te, chiang tak tak, gearbox housing leh motor housing te tan hman a ni ber.

Permanent Mold Casting: Aluminium alloy parts, wheel hub leh bracket ang chi, volume sang tak-volume siamna atana hman thin.
