High Pressure Aluminum Die Casting part for Gear Box
The part has requirement of powder coating treatment, so the density of the part is very important, unqualified part usually have a lot of void inside. So the mold design is very important, such as the layout of the location of the injection gate, runner, venting system etc. The technology of powder coating has process of curing in oven under about temperature of 200 degree, in this case, the porosity inside of the parts will expand to get out, leading to bubble on the part surface, such defect is unacceptable.
It is a part which is used as Mount head on Gearbox system. The technology for this part is high pressure Die Casting. Our factory specializes in this industry for more than 16 years. The material for this part is ADC-12, a most common aluminum alloy in die casting industry.
For this product, we should pay close attention to deformation
Features: the overall deformation of the casting geometry does not meet the design requirements.
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.
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.
What's more, for the design of the mold, should attach great attention to the parting lines, considering the convenience for operation of deburring, polishing.
By the way, as an experience die casting producer, we usually will run solidification analysis prior to the built of the die.
