OEM graphite ring seals crucible for photovoltaic 

Product Description           First of all, graphite molds can be used for the pressing of cells during the preparation of solar cells. Solar cells are usually composed of multiple layers of material, including silicon, conductive layers and so on. Graphite molds can be manufactured into molds of various shapes according to design requirements, which are used to press and shape these materials so that they have the desired shape and size.           Secondly, graphite molds can also be used in the sintering process of solar cells. Solar cells need to be sintered at high temperatures during the preparation process to make the material more dense and stable. The graphite mold can withstand high temperatures and has good thermal conductivity, which can be used in the sintering process of solar cells to ensure the quality and performance of the battery.           In addition, graphite molds can al…
