The difference between die casting and investment casting

What is the meaning of investment casting?

Investment casting is also known as lost wax casting or dewax casting. Making parts with investment casting is usually a more time-consuming process of making the original shape of the wax for the part, which is then repeatedly infiltrated into liquid porcelain. The porcelain hardens and the wax dissolves, leaving the ceramic mold behind. Molten metal is then poured into the porcelain cavity. Once the ceramic mold has solidified, it is broken and removed, leaving the metal casting behind. The wax mold can be used multiple times, but the ceramic mold is broken and lost during the production of each part.

Advantages of investment casting technology.

1. Forging of light and non-ferrous materials

2. Smooth surface finish reduces machining and finishing

3. Thin-walled parts can be produced in complex shapes

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

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

Investment mold precision casting process is widely used: Investment mold casting is highly practical and applicable to common ferrous and rare metals. So it is used to manufacture many high precision and high accuracy parts, such as aircraft systems, engines and emission systems, agricultural equipment, hand tools, building hardware, bathrooms, industrial parts and their medical equipment.

Die casting is the forced placement of hot red liquid metal into a mold, and the die casting process involves being under extreme pressure. In this case, a "mold" is built of steel just to shape the specific product being manufactured. Once the liquid metal is poured into the mold, it solidifies and is then removed from the mold. The gate material, which is the source of maintenance of the liquid metal, is removed once the liquid metal is cooled and the product is finished.

Die casting advantages: high productivity, good economy

Disadvantages of die-casting.

1. Heat treatment is not possible, and castings are easy to produce porosity

2. Die casting is difficult for complex concave castings.

3. High melting point alloys (such as copper). Die-casting type short life of light metals)

4. Not suitable for small batch production due to high cost of raw materials.

Die casting is widely used, generally for the production of small and thin metal parts. These parts are used in many industrial and commercial products such as vehicles and communication products.
