1. High precision requirement: the processing precision of fuel cell mould is very high, especially for the bipolar plate, which is a key component. The thickness of the bipolar plate is usually only 0.4mm, which is manufactured by stamping in the mould, requiring high processing precision to ensure that the hydrogen can smoothly pass through the tiny grooves on the bipolar plate to carry out the electrochemical reaction.
2. Efficient machining method: Traditional machining methods include roughing with ball and fillet rectified hard milling cutters, semi-finishing and finishing with round nose cutters, and the whole process takes up to seven days. Through technological optimisation, the use of shaped non-standard tools for machining and a significant increase in machining efficiency through larger step-overs can ultimately shorten the machining time for a piece of mould to 3 days, increasing efficiency by more than a factor of 1.
3. The use of innovative materials: the traditional bipolar plate consists of graphite plate or composite plate composed of graphite and metal, while the pure metal bipolar plate has become the direction of development due to its smaller size, lighter quality, lower temperature resistance, lower cost and other advantages. Our 3 materials bipolar plate moulds can be customized according to customer requirements.
