Graphite Molds

Graphite mold can be used for casting of various metal or non-metal materials, including continuous casting or semi-continuous casting. Our products have good high temperature resistance, self-lubricating properties and corrosion resistance. They are ideal for use in industrial applications, such as the casting molding of gold, silver, jewelry, glass, etc.

Graphite molds advantages

Graphite molds have a number of significant advantages.

Excellent high temperature resistance

It can withstand high temperature environments of up to 2000°C or more without deformation or damage. This makes it excellent in high temperature casting processes.

Excellent chemical stability

It has good tolerance to most chemical substances, which can effectively resist the erosion of corrosive media. And ensure the service life of the mold in a harsh chemical environment.

High thermal conductivity

This makes the graphite mold can transfer heat quickly and evenly during the heating and cooling process. Helping to improve production efficiency and product quality.

Good mechanical processing performance

It is easy to carry out cutting, drilling, grinding and other processing operations, which can meet the production needs of various complex shapes.

Superior release performance

It can effectively reduce the adhesion between the product and the mold. And improve the molding quality and production efficiency of the product.

Types of graphite mold

Graphite molds for metal casting:

These include use for metals such as gold, silver, copper and aluminum. You can specially use them in the metal casting industry. For example, in the casting of aluminum alloy auto parts, it can ensure the smooth flow of metal liquid in the mold and fill the cavity, casting parts with complex shapes and high precision requirements. This kind of mold can ensure the fluidity and filling of metal liquid. So that the casting has good surface quality and internal organization.

Graphite molds for glass:

Designed for glass production process, with good thermal and chemical stability. In the glass molding process, it can help the glass to accurately shape the desired shape. It can withstand the high temperature of the glass liquid and ensure the surface finish of the glass products.

Graphite molds for jewelry:

For the casting of jewelry, the precision and surface quality of the mold is very high. It can produce a variety of fine and complex jewelry shapes to help jewelry artisans realize unique design concepts. This type of mold usually needs to have good demoulding performance to ensure the integrity and beauty of the jewelry casting.

In addition, you can also choose graphite ring mold, graphite skull mold, graphite bar mold, graphite coin mold, graphite marble mold, etc. According to your specific needs, we can also make custom graphite molds. They will be processed to fit your size requirements.

Making a graphite mold

To make a graphite mold, the following steps need to be carried out:

Step 1. Selection of raw materials

Select high-quality graphite, such as high-purity graphite blocks processed from graphite ingot, usually without special additives or binders. After the initial treatment of these raw materials, they will become graphite mold blank, the basis for subsequent processing.

Step 2. Preliminary processing

According to the design, the graphite is cut into preliminary shape with cutting equipment to remove excess parts.

Step 3. Precision machining

With the help of CNC machine tools and other CNC equipment, precisely machine the detailed structure of the mold to ensure dimensional accuracy.

Step 4. Surface treatment

Improve the surface finish of the mold by grinding and polishing to meet the needs of use.

Uses of graphite mold

The application field of graphite mold is extremely wide, the following are some of the main application scenarios:

Metal casting industry:

In the metal casting process, you can use it to manufacture various metal parts. Such as the cylinder block and cylinder head of the automobile engine, gear and shaft parts in machinery manufacturing. Its high temperature resistance and good thermal conductivity contribute to the rapid cooling of metal liquid forming. And improve the quality and production efficiency of castings. The chemical stability of it can prevent the chemical reaction of the metal liquid with the mold during the casting process. And ensure the purity and performance of the metal parts.

Glass industry:

In the production of glass products, you can use graphite molds to make glass tubes, bottles, glassware and other products. The thermal stability of the graphite mold can adapt to the high temperature environment of the glass liquid. And in the glass forming process, the surface smoothness of the mold can ensure the appearance quality of the glass products. In addition, the durability of the graphite mold allows it to run stably for a long time on the glass production line, reducing production costs.

Jewelry industry:

It can accurately copy a variety of jewelry design patterns, through the casting process to make metal materials into exquisite jewelry. The high precision and good demoulding performance of the graphite mold ensure that the details of the jewelry castings are clear and the surface is smooth. This reduces the workload of subsequent processing and improves the efficiency and quality of jewelry production.

Aluminum casting:

Such as automobile wheels, aircraft parts, mechanical parts, etc. The use of graphite molds can improve the quality of castings and production efficiency, while reducing scrap rate and material waste.
