Graphite Block For Casting

Advantages of graphite block for casting

It comes in various shapes such as rectangular, cubic, and irregular blocks, and it has quite remarkable advantages.

Excellent high-temperature resistance

It maintains structural stability in a high-temperature casting environment ranging from 1200°C to 1800°C. And it will not deform or crack due to metal liquid impact or high temperature.

Low thermal expansion coefficient

During high-temperature heating and cooling, it can ensures the forming accuracy of the casting and reduces casting deformation errors.

Stable chemical properties

Graphite blocks are not prone to chemical reactions with non-ferrous metal liquids at high temperatures. Thus avoiding contamination of the casting and ensuring the purity of the casting.

Smooth surface is smooth and does not stick to the metal liquid

This reduces defects such as sand sticking and burrs on the casting surface, improving the surface quality of the casting.

Good mechanical processing performance

You can precisely process the casting into an irregular structure according to its shape, which adapts to various casting requirements.

Long service life

It is resistant to wear and impact, so it can be reused for multiple casting productions, reducing casting costs.

Uses of graphite block for casting

Non-ferrous metal casting field

The cavity of die-casting molds

You can use it in the production of precision aluminum alloy parts such as car wheels and laptop computer casings. It can reduce the demolding resistance and ensures a smooth surface of the castings.

The core chaplet

You can use graphite blocks in the casting of copper alloy valves and pipe fittings to form internal through-hole structures. It avoids the occurrence of defects such as shrinkage cavities and porosity in the castings, enhancing the mechanical properties.

Special alloy casting field

In the casting of aircraft engine blades

You can use graphite blocks to create precise cores with their high-temperature resistance and low impurity properties. It supports the formation of the high-temperature alloy liquid, ensuring the accuracy of the complex cooling channels inside the blades.

In the casting of special steel components in the nuclear power field

It acts as auxiliary blocks for molds to control the cooling speed of the castings, reducing internal stress.

Precision casting field

In jewelry casting

You can process graphite block to form the cavity of jewelry molds, and pour precious metal liquids into it. The high-precision processing performance ensures that the jewelry has clear patterns and precise dimensions.

In the casting of medical device parts (such as artificial joint components)

You can use it as core blocks to form the complex internal structure of the parts. Its chemical stability ensures that it does not contaminate biocompatible alloys.

General mechanical casting field

In the casting of general mechanical parts

In the casting of cast iron or cast steel parts

You can use it as auxiliary positioning blocks to cooperate with the mold, reducing the eccentric error of the castings.

In the casting of agricultural machinery parts (such as gears and bearing housings)

You can use it to make simple core block, reducing the production difficulty of complex castings.
