The thermoforming and the hot embossing are the forming processes for the plastic and the composite materials. The thermoforming heats the plastic sheet and forms it over a mold. The hot embossing presses a heated mold into the material to create a pattern. The mold is a key component of these processes, and the mold material must withstand the forming temperature and provide the precision. Graphite is used as the mold material because of its high-temperature stability, good thermal conductivity and precision.
The graphite mold for the thermoforming provides a uniform temperature distribution, which improves the quality of the formed product. The graphite mold for the hot embossing provides the precise pattern and the release. The graphite material for the molds must have good thermal conductivity, high-temperature stability and appropriate strength. The design of the mold, including the cavity shape and the surface finish, determines the quality of the product.
The technical requirements for the graphite molds include the high-temperature stability, the thermal conductivity, the dimensional accuracy and the surface quality. The material selection considers the forming temperature and the product requirement. The high-density fine grain graphite provides a good surface quality. The precision machining of the mold ensures the accurate dimensions and the pattern.
The application of the graphite thermoforming and hot embossing molds is found in the packaging, the automotive and the electronics industries. The forming of the plastic and the composite materials for these industries uses the graphite molds. The development of the industries drives the demand for the high-quality graphite molds.
