[0045] Example 1:
[0046] see figure 1 , a new type of infiltration treatment process for die-casting sheet, comprising the following steps:
[0047] S1. Use high-pressure water to spray the surface of the die-casting sheet to remove the dirt attached to the surface, then dry and polish;
[0048] S2. Degrease and degrease the die-casting plate, then rinse it twice with clean water, and dry it with heated oxygen in a closed space;
[0049] S3. After drying, a magnetic field is applied on one side of the die-casting sheet surface, and the other side is covered with reducing iron powder, and the reducing iron powder enters the micropores on the surface of the die-casting sheet under the action of the magnetic field;
[0050] S4. Cover both sides of the die-casting sheet with a double-effect film and take it out of the closed space. After standing for 20 minutes, start the magnetic field again, and inject the infiltrating liquid into the double-effect film at the same time to t...

[0062] Example 2:
[0063] A new type of impregnation treatment process for a die-casting plate, comprising the following steps:
[0064] S1. Use high-pressure water to spray the surface of the die-casting sheet to remove the dirt attached to the surface, then dry and polish;
[0065] S2. Degrease and degrease the die-casting plate, then rinse it with clean water for 3 times, and dry it by hot blowing with heated oxygen in a closed space;
[0066] S3. After drying, a magnetic field is applied on one side of the die-casting sheet surface, and the other side is covered with reducing iron powder, and the reducing iron powder enters the micropores on the surface of the die-casting sheet under the action of the magnetic field;
[0067] S4. Cover both sides of the die-casting sheet with a double-effect membrane and then take it out of the closed space. After standing for 25 minutes, start the magnetic field again, and inject the infiltrating liquid into the double-effect membrane a...

[0073] A new type of impregnation treatment process for a die-casting plate, comprising the following steps:
[0074] S1. Use high-pressure water to spray the surface of the die-casting sheet to remove the dirt attached to the surface, then dry and polish;
[0075] S2. Degrease and degrease the die-casting plate, then rinse it with clean water for 3 times, and dry it by hot blowing with heated oxygen in a closed space;
[0076] S3. After drying, a magnetic field is applied on one side of the die-casting sheet surface, and the other side is covered with reducing iron powder, and the reducing iron powder enters the micropores on the surface of the die-casting sheet under the action of the magnetic field;
[0077] S4. Cover both sides of the die-casting sheet with a double-effect membrane and then take it out of the closed space. After standing for 30 minutes, start the magnetic field again, and inject the impregnating liquid into the double-effect membrane a...
