You tell the employees that they are working for a HDD factory. A small number of people at the top of the company are in on it and keep sales limited to one or a small number of clients, all of whom are the clandestine buyer.
That would be similar to the way in which the fake Swiss cryptographic machine manufacturer was run. Their only leak risks were from employees who realized that their cryptosystem was easily broken. An HDD manufacturer would not have that problem because all of its work would be perfectly legitimate.
