Simple but not easy,the 3D light box letters and numbers are upgraded on the basis of the traditional light box letters and numbers.The biggest nemesis of the traditional light box letters and numbers is 'Deformation', and the 3D light box letters and numbers are as meticulous as they are,no flaws. How to do it without deformation, First of all, the first step process must be laser-cut, and the optical fiber in laser cutting is precisely cut quickly, with high precision, faster speed, less pollution, cutting edgeless tooth plating, and no deformation to ensure shape perfection.
Welding and crimping technology is the most important. It must be matched with imported professional edge-bending machines,rejecting manual crimping, and adopting lower heat welding to ensure better fusion between different materials and same materials. The grinding depth is no more than 0.2mm., you can achieve.
