Examples of automotive engine components that are being coated are fuel injection parts like injection needles, high pressure plungers, orifices valves, piston rings, valve train components like rockerarms and tappets, piston pins, roller and sliding bearings, gears and many others. Lately, in order to reduce emissions even further, industry is investigating other engine parts as well, like dynamic seals (friction reduction), batteries and fuel cells (electrification of powertrains).
Bipolar Plate Coating Solutions
Hauzer has applied its long experience on carbon-based coating processes and technologies to metallic bipolar plates for PEM type fuel cells. Good results in terms of adhesion, conductivity and corrosion resistance have been obtained by implementing plasma surface cleaning and a special adhesion layer in the total coating solution. Cost of ownership values for pilot and high volume production are highly attractive and well in line with Industrial roadmaps. More detailed information on the coating performance tests by Fraunhofer and ZBT and high volume manufacturing cost models are available.
Hauzer’s carbon coating for bipolar plates has been developed at its competence center in the Netherlands. Dedicated equipment is available to test various processes on customer products.
Hauzer can provide coating services at partner facilities. This service can be used by customers who would like to coat a large quantity of products on frequent basis or gradually want to ramp up production volume.
R&D and Pilot Equipment
Hauzer is off ering batch tools that can be used for R&D and for pilot scale production. The Flexicoat® 850 is the smallest tool that can be equipped with various deposition technologies for process and coating development. The Flexicoat® 1500 is the largest batch tool that can be used for pilot production – up to 500,000 bipolar plates can be coated annually (A4 size, both sides coated).
Hauzer Inline machines coat millions of components every day. They are built for 24/7 mass production of two or three dimensional components and can easily be integrated in highly automated factories. The equipment can be expanded whenever production growth is needed. The Metalliner® can be configured for an output range of 1 million (entry level) up to 10+ million coated bipolar plates per year. Platforms for steel coil coating will be launched when market demands have grown to substantial levels.
