Forming process steps of die-casting aluminum alloy

Die casting is actually a method of obtaining castings by filling the cavity of a die casting mold with liquid or semi liquid metal at a higher speed under high pressure, and forming and solidifying under pressure. It has the advantages of high production efficiency, high dimensional accuracy of castings, and good surface quality. 

Most die-casting alloys are free of iron, such as zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys and their alloys. Depending on the type of die casting, different materials of release agents are required.

The die-casting process method includes the following steps:

1. Cleaning the mold: Clean the mold thoroughly and spray release agent;

2. Mold closing: Control the mold to close and form a die-casting cavity and runner;

3. Oxygen filling process, using industrial oxygen cylinders to charge industrial oxygen into the injection chamber;

4. Pouring metal liquid: Pour the metal liquid into the injection chamber;

5. Punch injection: Control the injection punch to squeeze into the injection chamber, filling the metal liquid in the injection chamber into the die-casting cavity through the runner;

6. Metal liquid solidification: After the metal liquid is completely filled in the die casting cavity, the injection punch maintains a certain pressure until the metal liquid cools and solidifies;

7. Mold opening and parts removal: After the metal liquid solidifies, control the mold to open, reset the injection punch, and remove the die casting.

The correct selection of die casting release agent effectively improves the product release effect and production efficiency. The recommended MK-TD1 die cast aluminum alloy release agent can help you solve the following problems: 1.

1.Excellent release performance,

2. Special grade surface finish,

3. Fully protect the mold,

4. No carbon deposition performance,

5. Excellent high-temperature resistance,

6. Good cooling effect,

7. High safety performance.
