The brothers secured multiple patents to protect their frames, including the copper hinge design, which is also the inspiration for the company name.

The factory will also take over some of the manufacturing for Erker’s wholesale business.

But even though the machines make the process look easy, it’s been a long road. An improvement in technology helped make the concept a reality. Just five years ago, five machines were required to make the nose bump. Now, one does it, Jack Erker said.

It’s unique to have so much automation, the men said. Many of the overseas factories still rely heavily on workers.

In California, near Silicon Valley, Daniel Lau relies on his 10 workers to make frames by hand instead of using automation.

“We’re one of the survivors,” said Lau, 44, who took over the business from his father.

It’s a tough business, he said, but being American-made is a big draw for consumers. He sells about 50,000 to 60,000 eyeglasses each year under his own brand, Kala Eyewear.

Copper Hinge will have the ability to make at most 2,500 frames per employee per month, Jack Erker said. He and his brother hope to have 14 employees.
