Quality zinc die casting knuckle for Sale

Aluminium Alloy Precision CNC Die Casting Gear Reducer Parts with Competitive Price, 

The cavity number for this part is 2, according to the required tolerance and dimensions in terms of the prints, the part has difficulty on CNC machining, the wall thickness is small, not much machining allowance left. The part is a kind of motor housing, the bore is used to assemble the bearing, so the concentricity requirement is higher than the other parts. Meanwhile, as the housing for bearings, the part has definite mechanical property requirement. 

the material for this part is ADC-12, a kind of material, having good fluidity, which is good for filling while die casting. This material is a good material to produce end cover, housing, gearbox, bracket etc. The composition of ADC-12 is:(Cu)1.5~3.5,( 58218061, 54193430,Si)9.6~12.0,( 58218062, 54193431,Mg)≤0.3,( 58218063, 54193432,Zn)≤1.0,( 58218064, 54193433,Fe)≤1.3,( 58218065, 54193434,Mn)≤0.5,( 58218066, 54193435,Ni)≤0.5,( 58218067, 54193436,Sn)≤0.3,( 58218068, 54193437,Pb) ≤0.1,( 58218069, 54193438,Cd) ≤0.005,( 58218070, 54193439,Al) the remaining.

For this product, we should pay close attention to deformation

Features: the overall deformation of the casting geometry does not meet the design requirements.
Causes
1, the casting structure design is bad, cause uneven contraction.
2, mold opening too early, casting rigidity is not enough.
3, too small casting inclination.
4. Improper operation of casting.
5. Improper placement of push rod.

Exclusion measures

1, improve the casting structure, so that the wall thickness uniformity.
2, determine the best mold opening time, strengthen the casting rigidity.
3. Enlarge the inclination of casting.
4, take the casting should be careful, handle with care.
5. The application of special box for casting and the way of removing gate should be proper.
6. Some deformed castings can be eliminated by shaping.
