1. Characterisation of Functional Pressing Die Surfaces
Abstract : The manufacture of dies and moulds is a critical aspect of many production systems since the manufacturing and try-out of new dies and moulds often is essential in determining the lead-time and quality of a new production system. In the automotive industry, many new car models are introduced each year and for each of these models, a new set of pressing dies has to be designed and manufactured. READ MORE

3. Experimental approaches to powder filling and lubrication in powder die pressing
Abstract : There is a continuous need to improve the mechanical properties of steel parts produced through powder metallurgy in order to ensure the market growth of this sector and competitiveness against alternative production techniques. One of the more promising routes able to achieve this is to aim for components with higher densities. READ MORE

4. Friction in metal powder pressing : measurement and characterisation
Abstract : The present work describes different methods for measuring and characterisation of friction in powder compaction process. A new test apparatus has been developed and presented which gives possibility of directly measurement of coefficient of friction during pressing from low to relative high density. READ MORE
