How to store aluminum alloy die castings correctly? Usually, we provide a large number of aluminum alloy die castings, but a large number of zinc alloy die castings cannot be assembled quickly. Therefore, this is related to the storage of die castings; The following are the problems that should be paid attention to by yuhuasheng die casting manufacturer and prepreg:
1. Aluminum alloy die castings need to be placed in a ventilated and dry environment when stored;
II. Avoid chemical contact with other die casting elements. Contact with other chemical elements will bring other changes to aluminum alloy die casting;
3. As aluminum is an active metal, it is easy to oxidize after exposure to a certain temperature. Always avoid direct sunlight when placing aluminum alloy die castings;
Fourth, if the aluminum alloy die castings can be placed in a specific position, it is best to ensure that the aluminum alloy die castings are not damaged and will not have any other changes;
Prepreg:
The prepreg solution is (2 ~ 8)% NaCN solution, which is used to purify and activate the surface; Immersion die castings can be directly pre plated without cleaning, which can not only prevent the coarseness and blistering caused by the displacement reaction of the workpiece before energization in the groove, but also reduce the impurity pollution of the pre plated layer- Plating solution to improve the quality of pre coating.
