Auto Parts Factory Introduces The Production Process Of Die Casting Parts

The traditional die-casting process mainly consists of four steps, or it is called high-pressure die-casting. These four steps include mold preparation, filling, and sand falling, which are also the basis for the improved die casting process. During the preparation process, a lubricant needs to be sprayed into the mold cavity. In addition to helping to control the temperature of the mold, the lubricant can also help de-mold the casting. Then you can close the mold and inject molten metal into the mold with high pressure. The pressure range is about 10 to 175 MPa. When the molten metal is filled, the pressure will be maintained until the casting solidifies. Then the pushrod will push out the casting. Since there may be multiple cavities in a mold, multiple castings may be produced during each casting process.

The doffing process requires the separation of residues, including mold openings, runners, gates, and flash. This process is usually done by extruding the casting with a trimming die. Other methods of doffing include sawing and sanding. If the gate is fragile, the casting can be beaten directly, which can save manpower. The excess mold opening can be reused after melting.

High-pressure injection results in a fast filling of the mold so that the molten metal can fill the entire mold before it partially solidifies. In this way, even thin-walled parts that are difficult to fill can prevent surface discontinuities. However, this can also lead to air entrapment because it is difficult for air to escape when filling the mold. This problem can be reduced by placing the exhaust port on the parting line, but even the precise process will leave pores in the casting part.

Auto Parts Factory introduces that automobile die-casting is a kind of pressure casting part. It uses a pressure-casting mechanical die-casting machine equipped with a casting mold to pour liquid copper, zinc, aluminum, or aluminum alloy into the feed of the die-casting machine. The mouth is die-cast by a die-casting machine to cast copper, zinc, aluminum parts, or aluminum alloy parts of the shape and size restricted by the mold. Such parts are usually called die castings.

Through the above introduction, Motorcycle Parts Factory hopes that you can simply refer to the content of this article in future use.
