The present invention relates to a support bar capable of enhancing durability and productivity and saving material costs for the support bar by improving the structure of the support bar for a glass loading cassette. The present invention is formed by inserting a glass fiber extrusion panel or carbon fiber extrusion panel into glass fiber reinforced plastic and carbon fiber reinforced plastic in order to reduce material costs and enhance the durability of the support bar. An upper surface formed to be wider than a lower surface to enable easy form removal. The upper surface of a core is narrow and the lower surface of the same is wide, the upper width of a forming part of a mold to form the support bar is wide and the lower width of the same is narrow to insert the carbon fiber extrusion panel between the glass fiber reinforced plastic and the carbon fiber reinforced plastic. Therefore, the core is inserted into the forming part of the mold to manufacture the support bar through heating and cooling. According to the present invention, the lower surface is formed to be wider than the upper surface and the glass fiber extrusion panel or carbon fiber extrusion panel enhances the durability of the support bar. Since the support bar is formed with the narrow upper surface and the wide lower surface, the support bar is easily removed from the mold to prevent damage to the support bar and improve productivity. |
