Everyone knows that with the development of the manufacturing industry, there are more and more application fields of aluminum alloy die castings, and the requirements for surface treatment are also changing with each passing day. So what are the details of the surface treatment of aluminum alloy die castings?
Details of the surface treatment of aluminum alloy die castings:
1. The surface of aluminum alloy die castings needs to be polished to a certain extent, mainly to remove water marks and pits on the surface of die castings, and then spray oil after polishing, the effect will be better;
3. The polished and deburred die castings need to be ultrasonically cleaned before spraying to remove the polishing wax and some impurities on the surface, so that the sprayed die castings have a better texture;
4. For die-casting parts that need to be assembled with other counterparts, fixture shielding treatment is required before fuel injection. Because the coating of fuel injection is a bit thick to avoid poor assembly with counterparts, this link cannot be omitted.
