Abstract: Laboratory heat press consists of furnace part equipped with dilatometer which is placed beneath removable double-acting pneumatic cylinder anchored on four shafts, of power supply and of computer which regulates process and collects data, while in the working space is situated graphite press die with sample, which is placed on sliding piston holder and the device is equipped with control electronics. Heating equipment is graphite element, and around the element are situated graphite shields made from solid graphite and graphite wool insulation. Outer shell of furnace and both flanges are water cooled. Flanges are equipped with holes for thrust pistons and the furnace shell contains hole for connecting the vacuum pump and hole for installation of the pyrometer. Graphite pressing die with sample is equipped with pistons, which are influenced by power from double-acting pneumatic cylinder, while on the both graphite pistons are graphite radiative rings and between them is graphite wool.
