To gain the theoretical and practical knowledge which is necessary to project and design technology and dies for powder forming.

Students can apply the gained theoretical and practical knowledge to design technology, dies and to select machine tools for powder forming.

Analysis of powder compression, process parameters and their optimization. Modeling and simulation (MKE) of powder compression as a function of die design and machine selection. Dies for powder compression, floating die, elements for motion of die components, powder dispenser. Extrusion dies for powder forming, calculation and design. Injection pressing dies for powder compression. Rolling dies for powder forming. Dies for cold and hot isostatic forming of powder. Dires for hot and cold calibration of powder parts. Forging dies for powder forming.Machine tools and other needed equipment for powder forming and their classification. Presses for powder forming (mechanical, hydroulic, hyfromechanical).Adapters for load transfer to mobile die elements, powder dispensers, machine control system. Rolling machines , injection pressing machines, presses for osostatic pressing, presses for calibration of sintered parts, presses for forging of powder parts. Automatic lines for forming of powder parts , ancillary equipment, powder mixing machine, transport system for green parts. Methods for powder forming, hot and cold forming, continuous methods, cyclic methods, isostatic compression. Accuracy of powder parts, net shape technology. Afterwards forming of sintered parts. Methods of hot and cold calibration. Theory of the metal powder forming. Density and porosity of powder parts, research methods. Deformations and stresses in metal powder compression. Radial and axial stresses. Friction, lubrication. Determination of loads and stresses. Limit possibilities of powder pressing, destruction. Analysis of powder forming and its optimisation. Dies and machines and ancillary equipment.

Lectures are realized with active student participation in lectures and practical classes. Possible issues are discussed in consultations in separate term.
