Printers Prime Group of Nottingham transformed its operations and hired an additional 30 people ready to make up to a million visors per month, or 35,000 per day.
But the firm is frustrated that despite contact with the authorities a month ago, no orders have been placed.
It has already delivered 350,000 to the front-line NHS and to healthcare workers here for free or at cost.
But boss Jon Tolley revealed they couldn’t get a big order from the NHS after investing £ 250,000 on the materials.

Instead, he dealt with NHS trusts for orders of 1,000 to 30,000 visors.
By the end of this week, there will be 100,000 in stock with no designated buyers, which may end up being sold overseas.
It needs an agreement to guarantee the jobs of its own workers.
Jon said, “I have the equipment to make another 500,000. I have to decide whether or not to sell this material in Europe because there is a demand. They are already making our creations. “
He decided to make the visors after his wife, an intensive care nurse, told him about shortages.
“My wife changed jobs in March and told me she was in desperate need of PPE,” said Jon, 47, whose visors have been approved by clinicians.
“We had nurses contacting us in tears to tell us ‘please help us, we are desperate’.
“We say to the government, rather than importing from abroad, come to us.”
The government reports that it has received more than 8,000 offers of support from PPE providers.
Health Secretary Matt Hancock said, “We are accelerating progress to get back to all of these companies with a substantial response.”
