Silicon carbide (SiC) is a ceramic, typically sintered-multicrystalline. Single-crystal SiC has semi-conducting properties superior to silicon allowing smaller and thinner transistors and integrated circuits (Semi-Conductors), able to work at higher temperature and higher current/frequency. A key application is power electronics, which are important for e...

Many industries, including electronics and medical are interested in miniaturisation, but this requires the ability to machine increasingly small components with superior geometries and surface topologies. Our conventional electro-chemical machining (ECM) machines are sold to customers globally and operate at the macro-scale, attaining surface roughness ~...

In addition to our original scope, we now also wish to also investigate the following in our final quarter: Credit cards require a security secure holographic hot foil print on the reverse side of the card. The hot foil printing on to a rigid substrate is extremely difficult and holographic foil compounds this difficulty. We wish to investigate in this fi...

Current art electrochemical machines (ECM) are: (1) High cost; (2) Single axis; (3) Not modular i.e. additional axis modules and associated bearing rails/gears cannot be implemented limiting a diverse range of components that can be manufactured from a single ECM machine. (4) Current operations waste expensive material as 2-3 solid metal cathodes are manu...

Electro Chemical Machining (ECM) has advantages over conventional manufacturing (milling/turning) i.e. less material waste, able to machine any conductive metal & higher quality surface finish. pECM systems Ltd (PSL) believe ECM technology could be advanced. Current cathode development is lengthy & high cost, machined to high surface finish from materials...

Pulsed Electrochemical Machining (pECM) uses the principles of ECM but pulsed voltage/current providing; lower current improving energy usage, lower material removal rate & better surface finish, vastly improved dimensional accuracy machining hard/high strength, temperature resistant materials, smaller machining gaps between cathode & workpiece to produce...
