The casting and forming processes use molds and dies to shape the molten metal and the plastic materials. The release of the product from the mold is an important consideration, and the mold release agent is used to facilitate the release and improve the surface quality. Graphite is used as a mold release agent and a lubricating coating because of its high-temperature stability, self-lubricating properties and chemical inertness. The graphite release agent provides the release in the high-temperature casting processes.
The graphite mold release agent is applied to the mold surface before the casting, forming a thin lubricating layer. The graphite layer prevents the adhesion of the molten metal to the mold and facilitates the release of the cast product. The graphite also provides a smooth surface, improving the surface quality of the product. The graphite release agent is used in the metal casting, the glass forming and the composite processing.
The material forms of the graphite release agent include the graphite powder, the graphite paste, the graphite spray and the graphite coating. The graphite powder is applied by the dusting or the brushing. The graphite paste and the spray are applied in a liquid form, which dries to form the coating. The selection of the form depends on the application and the mold type. The graphite coating can be formulated with the additives to improve the adhesion and the durability.
The application of the graphite release agent requires the proper preparation of the mold surface and the control of the coating thickness. The mold surface should be clean and dry before the application. The coating thickness should be controlled to provide the release without the contamination of the product. The graphite release agent is reapplied periodically to maintain the release performance.
The technical requirements for the graphite release agent include the high-temperature stability, the release performance, the surface quality and the compatibility. The graphite must withstand the casting temperature. The release performance depends on the lubricating properties. The surface quality of the cast product is affected by the graphite. The compatibility with the product material is important.
