I'm no authority, but I 'm told Chinese New Year is in full swing over there. And apparently NOTHING interferes with Chinese New Year.
I sent out multiple emails to JBT competitors and Chinese metal alloy companies who manufacture heat sinks a couple of weeks ago , to make them aware of Bourque and Kryron. I received just 2 replies so far.
Both said they were out of office for an extended time due to Chinese New Year and would get back to me (still havent)
Not trying to explain away your lack of response, but apparently they take their New Year festivities as more than a day or 2 away from work. I'm sure someone here has some experience with the Chinese culture who can tell us more.
