Graphite Top Plates

Semicorex Graphite Top Plates are high-performance fixtures specifically engineered for use in the hot glass industry, particularly during the forming and handling of glass bottles. These Graphite Top Plates play a critical role in the production process, providing reliable support and secure holding of glass containers under extreme temperature conditions. Designed to withstand the demanding environment of glass manufacturing lines, graphite top plates ensure both the structural integrity of the product and the operational efficiency of the production equipment.

Manufactured from high-density, fine-grain graphite, these Graphite Top Plates offer superior thermal stability and excellent resistance to thermal shock. Graphite’s low coefficient of thermal expansion allows the plates to maintain dimensional accuracy during repeated heating and cooling cycles. This stability is essential for maintaining precise alignment and grip on the hot glass bottles without introducing stress or deformation to the container.

Graphite materials can be used as various tools and models for blowing, pouring, pressing, stretching and other forming processes in glass production, such as scrolls and sleeves, melting crucibles, liners, plug-ins and forming molds. Moreover, many common shapes have been standardized.

For parts that operate at high temperatures and need to be lubricated, graphite products are used instead of metal. No lubricating oil is required during use, and maintenance is very convenient. For example, graphite bearings can be used for flat pull spokes and steering spoke bearings for producing flat glass, copper sleeves for tunnel kilns, and clamping spoke heads for edge drawing machines.

Compared with the metal shell of mobile phones, 3D glass processing is still somewhat difficult. In the 3D glass hot forming process, the glass needs to be softened by high-temperature heating and fixed in the mold to obtain the required shape. 3D glass hot bending has high requirements for graphite. Graphite is required to have high purity and high density. The high purity requirement is mainly to prevent the oxidation of graphite at high temperatures to produce bubbles, thereby affecting the surface finish; the high density requirement is to prevent the collapse of the graphite mold, to increase its mechanical strength as much as possible, and to ensure that the mold life is greatly improved. The surface finish of the mold cavity directly affects the surface effect of 3D glass. The surface of the mold cavity is not only related to fine polishing, but also closely related to the diameter of graphite particles. Only the smallest possible particle diameter can produce a sufficiently smooth mold cavity.

Features

1.Low thermal conductivity

Reduce cracking/crizzles and thermal shock, which can make fewer rejects and improve yield, increase "melt-to-pack" ratio.

2.Excellent flexural and compressive strengths

Improves wear performance and impact resistance,makes the handling parts longer life, which can

reduce product maintenance downtime and further reduce production costs.

3.Low porosity

Reduces contact cracking and absorption of contaminants,which effectively improves yield and reduce production costs.

4.Anti-oxidation treatment

Improve wear resistance,which can extend products life and reduce production costs.
