Differences between Die Casting and Investment Casting

What does Investment Casting mean?

Investment casting is also called lost wax casting or dewaxed casting. Making parts by investment casting is usually a more time-consuming process, that is, making the original wax shape of the parts, and then repeatedly penetrating into the liquid porcelain. The porcelain hardens, the wax dissolves, leaving behind ceramic moulds. The molten metal is then poured into the porcelain chamber. Once the ceramic mold has congealed, it is broken and removed, leaving the metal casting behind. The wax mold can be used for many times, but the ceramic mold will be broken and lost in the production process of each part.

Advantages of investment casting technology:

1. Forging of light metal and nonferrous metal materials

2. Smooth surface treatment reduces machining and finishing

3. Thin wall parts can produce complex

4. High precision can directly produce goods with accurate specifications without post-processing

Disadvantages of investment casting: investment casting has high price and cost, and long delivery time

investment casting process is widely used: investment casting has high practicability, and is suitable for ordinary black and rare metals. Therefore, it is used to manufacture many high-precision and high-precision components, such as aircraft systems, engines and emission systems, agricultural machinery equipment, hand tools, building hardware, toilets, Industrial Parts and medical equipment.

Die Casting is to force hot red liquid metal into the mold, and the die casting process includes extreme pressure. In this case, the steel mold established by "mold" is only to shape the specific product being manufactured. Once the liquid metal is poured into the mold, it will condense and then be taken out of the mold. As the gate material of liquid metal maintenance source, once the liquid metal is cooled, it will be removed and the goods will be completed.

Die casting advantages: high productivity and good economic benefits

Disadvantages of die casting:

1. Heat treatment is not allowed, and castings are easy to produce air holes

2. Die casting is difficult for complex concave castings.

3. High melting point alloys (such as copper), light metals with short die casting life)

4. Due to the high cost of raw materials, it is not suitable for small batch production.

Die casting is widely used to produce small and thin metal parts. These components are used in many industrial and commercial products, such as vehicles and communication products.
