Before we started this technology development we wanted to set some targets and as far as real world kind of targets. We wanted to standardize to ten thousandths and twelve thousandths diameter wires. We wanted to focus on technology using brass and coated wires and paraffin or non paraffin types of wires and maybe many of you may not know what that is but paraffin is wax that's applied to the wire to decrease the amount of dust particles you get through your machine. Non paraffin wires basically take the paraffin off and you are able to grip the wire but you do add some maintenance to your machine and also high zinc. So what we wanted to accomplish is try to offer technology for no matter what wire you are using you'll be able to use this technology, to cover all our bases. We also wanted to provide practical high speed EDM performance in the most difficult, real world die mold or production medical aerospace or job shop application. We also wanted to develop this technology for thickness ranging from one inch to six inch to cover most of the work that's being done in these kinds of applications. We have also collaborated with many wire manufacturers to offer better solutions to improve upon the brass EDM process, to improve upon some of the shortcomings of coated wires. So we are developing very close relationships with some of these manufacturers to offer better solutions to you the customer. And of course this is an ongoing technology development. Not only do we have technology for this application but we are adding new as we speak more trim cuts per say total work pieces so different material. So you'll see some ongoing development as a result of this HEAT technology.
