Abstract
Microproduction is one of the fastest growing fields of industry with increasing demands from the market. A key factor in microproduction is micro-tooling. There exist various micro-tooling techniques, such as LIGA, electroplating, etc., which are very accurate but on the other hand also very expensive and time consuming. This contribution presents an alternative, which cannot compete with the above-mentioned technologies regarding the accuracy, but is time efficient and far more cost effective. The proposed micro-tooling strategy consists of producing the electrode for Micro Sinking Electrical Discharge Machining (MEDM) using Water Jet (WJ) technology. The final tool is produced by MEDM to be used for replication processes like hot embossing, molding, and others. Results obtained during this investigation indicate the appropriateness of the proposed micro-tooling strategy for the development and design of microfluidic devices, due to the specific characteristics of the involved technologies.

K.U.Leuven is one of the three divisions of the department of Mechanical Engineering. PMA is active in the following areas: manufacturing processes, machine and instrument design, structural dynamics, acoustics, CAD/CAM/CIM, robotics, assembly automation, mechatronics, micro- and precision engineering, and metrology. The PMA division work includes original fundamental work as well as successful industry-oriented projects carried out in collaboration with small, medium and large companies and with international organisations like the European Space Agency. An important role of the research activities of the PMA division is based on international collaboration as shown by the participation of the division in more than 40 EC funded projects. The PMA division has also been nominated as Centre of Excellence by the Belgian Government.
