The difference between die casting and investment casting

What does investment casting mean?

Investment casting is also called lost wax casting or dewaxing casting. Making parts with investment casting is usually a more time-consuming process, that is, making the wax original shape of the part, and then repeatedly penetrating into the liquid porcelain. The porcelain hardens and the wax dissolves, leaving the ceramic mold. The molten metal is then poured into the porcelain cavity. Once set, the ceramic mold is broken and removed, leaving the metal casting. Wax molds can be used multiple times, but ceramic molds are broken and lost during the production of each part.

The advantages of investment casting technology:

1. Forging of light metal and non-ferrous metal materials

2. Smooth surface treatment reduces machining and finishing

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

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

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

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, construction hardware, toilets, industrial parts and medical equipment.

Die casting is to force the hot red liquid metal into the mold. The die casting process includes extreme pressure. In this case, the "mold" is created by the steel mold just to shape the specific product being manufactured. Once the liquid metal is poured into the mold, it will condense and then be removed from the mold. As the gate material of the liquid metal maintenance source, once the liquid metal is refrigerated, it will be removed and the commodity will be completed.

Die casting advantages: high productivity, good economic benefits

Disadvantages of die casting:

1. Can not be heat treatment, casting is easy to produce pores

2. Die casting is difficult for complex concave castings.

3. High melting point alloy (such as copper). die-cast light metal with short life)

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

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