Awhile ago, I posted a request for information on purchasing a hot embosser. I have finally summarized what people emailed me and what I learned while purchasing this machine. There is only a single supplier of hot embossers designed for micromachining applications; Jenoptik (they have a web page). There are other companies that supply hot embossrs, but they are for more tradiational industries. It is unclear if these other machines will do what the MEMS community needs. I received e-mail from people who were considering building their own machines, but I don't know how that has progressed. The feeling in the MEMS community is that the present Jenoptik machines are R and D/small production run machines, not machines for mass production. This isn't surprizing considering the infancy of the plastic MEMS field. I would assume as soon as someone needs a production machine, that a comapny somewhere will offer it.
