Graphite Mold for Glass

Advantages of Graphite Mold for Glass

Glass graphite mold can be processed into various shapes according to different glass production requirements, and its advantages are very remarkable.

Excellent high-temperature resistance

It can remain stable in the high-temperature glass forming environment of 1000℃-1600℃ without deformation or damage.

Extremely stable chemical properties

It hardly undergoes chemical reactions with molten glass and ensures the purity and quality of glass products.

Uniform heat conduction

It enables the glass to cool and form rapidly and evenly in the mold which effectively enhances production efficiency.

Excellent demolding performance

Its surface is smooth, so it can reduce the adhesion between glass products and molds, lower the scrap rate. And it also facilitates the cleaning and reuse of molds.

High mechanical strength and excellent wear resistance

Even after multiple uses, it can still maintain good shape accuracy and extend the service life of the mold.

Types of Graphite Mold for Glass

Forming mold:

Specifically used for giving glass products specific shapes, such as the forming of bottles, bowls, plates, etc. The design of this type of mold needs to be precisely processed according to the final shape and size of the glass product. To meet the appearance and usage requirements of the product.

Annealing mold:

It is used in the glass annealing process, which main function is to support and fix the glass products. It can eliminate internal stress during the slow cooling process of the glass and prevent defects such as cracks.

Uses of Graphite Mold for Glass

Glassware manufacturing:

You can use graphite mold to produce various glass vases, wine glasses, tableware and other glassware. It can precisely shape the forms and details of the vessels. Its excellent demolding performance makes the surface of glassware smooth and the contour clear after forming. This reduces the subsequent grinding and processing procedures, and improves production efficiency and product quality.

Architectural glass production:

In the production of flat glass, insulating glass and other architectural glasses, you can use it for the forming and shaping of the glass. Because of its excellent thermal conductivity, you can cool and shape the glass rapidly, ensuring the flatness and dimensional accuracy of the glass. And meet the strict requirements of the construction industry for the quality and specifications of glass.

Optical glass processing:

You can use it to manufacture optical lenses, prisms and other optical glass products, high-precision. Its stable chemical properties and high-precision processing dimensions can ensure that optical glass is not contaminated during the forming process. And it has excellent optical performance, providing high-quality glass components for the manufacturing of optical instruments.

Special glass production:

You can also use it for some special-performance glasses, such as high-temperature resistant glass and radiation-resistant glass. Graphite mold can be used normally under complex conditions such as high temperatures and special chemical environments. It ensures the stability of the forming and performance of special glasses. So it plays an important role in the manufacturing of special glass in fields such as aerospace and nuclear industry.
