Graphene film can be used as a heat sink in electronic components. The heat sink is usually attached to the surface of electronic components that are prone to heat to evenly disperse the heat generated by the heat source. The one with the highest thermal conductivity and the best heat dissipation effect is made of polyimide. The artificial graphite heat-conducting film obtained by the graphitization process of the film requires a 1,000-ton graphene vacuum forming hydraulic press to produce the graphene heat-conducting film.

500-ton and 1,000-ton graphene vacuum forming hydraulic machines are commonly used to make graphene heat conduction film, and the size and model can be customized. Graphene heat conduction film sheet flat press machine, suitable for different thicknesses of graphene heat dissipation film, graphene shielding film, graphene conductive film vacuum flat pressing to improve product compactness, improve product thermal conductivity, heat dissipation, electrical conductivity coefficient of performance and diaphragm Density, the graphene conductive thermal film flat press machine currently developed can solve the common difficulties in the industry such as diaphragm bulging, material layering, low density, and low performance. Features of Hydraulic Press Machine for Graphene Film Vacuum Forming: 1. The hydraulic press can adopt the overall frame or four-column structure, which can be customized according to product requirements. 2. The appearance of the hydraulic press adopts a fully enclosed structure to achieve a vacuum environment. The vacuum degree in the vacuum chamber of the machine is -0.1MPa, combined with a vacuum sensor and PLC man-machine interface for overall control. 3. The hydraulic press adopts a flexible pressurization control system, and is extruded by a flexible press process. The pressure can be increased in a curve of 0.1MPa, and the boosting time and holding time can be set arbitrarily. 4. The hydraulic system of the hydraulic press adopts a servo flexible oil circuit, and the boosting speed and time can be freely set according to the process requirements. 5. The control pressure of the electrical control part adopts precise multi-stage pressure. After setting the process, it can automatically pressurize according to the set process. Graphene thermally conductive film is easy to make a thermally conductive film with a large thickness (~100 μm), and has a good application prospect in the thermal management system of new electronic devices. Therefore, the research of graphene heat conduction film is also mainly along two directions, one is to improve the in-plane thermal conductivity of graphene heat conduction film, so as to approach or exceed the level of artificial graphite film. The second is to increase the thickness of the graphene heat conduction film to expand the heat conduction flux while maintaining good heat conduction performance. It can be seen that the design and development of graphene conductive heat film flat press needs to develop in a more precise, higher-end and more advanced direction.
