I used to have a laser engraving in my last company. I really didn’t know how to operate it at first, but with the training of the team leader, I’m familiar with laser engraving. Last time my husband said they bought a laser engraving. But a lot of people don’t know how to use it, and my husband knows how to use it. He’s in charge of everything in his company, including printing materials and carving products. It’s really over time. Now he’s also very familiar with laser engraving. It can even be a professional operator, bringing great benefits to the company.
