Graphite and metal dies are the most commonly used materials for press machines, with graphite being particularly popular for hot pressing equipment due to its low cost, ease of machining, and good thermal stability over a wide temperature range. Graphite dies offer low density, low resistance, and sufficient mechanical strength, with compressive strengths ranging from 35-45 MPa, and up to 70 MPa for high-strength graphite. However, graphite dies have limitations such as low mechanical strength under high pressure and reactivity with certain materials like oxides, transition metals, nitrides, and silicides.
Metal dies, especially copper alloy dies, are also widely used, particularly for making polycrystalline optical materials like magnesium fluoride, magnesium oxide, and lead selenide. Oxide and ceramic dies are less common due to their poor thermal stability, difficulty in processing, and compatibility issues with the pressed material.
Hydraulic presses, which are versatile and efficient machines used in various industrial processes including metalworking, plastics processing, and woodworking, utilize these dies. They are designed to generate compressive force using fluid power and can perform operations such as forging, punching, blanking, deep drawing, and forming. The choice of die material in hydraulic presses depends on the specific requirements of the application, such as the material being processed and the conditions under which the press operates.
