Basics of Permanent Mold Casting

Permanent mold casting is a process that includes the use of permanent or reusable molds. Chill casting is another term used to refer to the same process. In this article, we will learn about this process. Read on to find out more.

In permanent mold casting in aluminum die casting mold, there is the involvement of a two-piece mold. However, these pieces are made up of iron or steel and these parts are put together. To receive molten metal there is a hole on the top of the mold. Both of the pieces are separated once they are cooled down. In case the casting structure is too complex there are high chances that the mold has some slits on it. They have to perform tooling to fix this problem.

They need to preheat the mold at the beginning of the process. From the mold this stage removes moisture and in the molten metal, it maintains the temperature. Another advantage of preheating is that thermal expansion prevents the mold from damage. When the molten metal is poured into it this expansion happens.

To pour molten metal in the mold from aluminum die casting mold manufacturers, different means are used. However, there are a few common methods. This method is the best as far as cost is concerned as it doesn't require a lot of equipment. 

In such a case, into the mold, the liquid is inserted with pressure. The vacuum insertion method can also be used at alternate times. The right method is used based on the needs so that the best results can be achieved.

Special Features of Permanent Mold Casting

• The need for other machining operations is reduced
• It allows the casting of thin walls
• It even allows the casting of other pins and inserts
• The production of lighter parts is also allowed
• It has some better mechanical characteristics
• Great dimensional accuracy is offered
• It is economical and cost-effective 
• Unlike other methods, it offers a smoother surface finish
