What is the role of Lens Protector?
1.Is to increase the light transmission, can reduce the multiple reflections of light inside the lens, the second is to a certain extent, so that the color reproduction more realistic, thus improving the quality of imaging.
2.To protect the Lens Glass Film from damage, do not worry about the wear and tear of the phone lens.
Mobile Phone Lens Film is fully transparent, does not change the color of the body, the use of laminating technology, for the Phone Camera Sticker position to play a very good protection, especially for people who are used to using the bare phone or just want to protect the lens surface is the most suitable.
However, if you want to keep the lens away from dust, you must ensure that the hole is accurate. If small bubbles or white edges are generated when the tpu hydrogel camera lens screen film is applied, dust can still easily enter through these "holes". Therefore, when you choose a lens film, it is best to buy a camera screen protector with automatic adsorption function, so that bubbles and white edges can be avoided, and dust can be drilled seamlessly.
What is the difference between a die cutting machine and a laser cutting machine?
1. Die cutting machine
Advantages: fast cutting speed, low cost, suitable for simple protective film with low precision, blade cutting, smooth edges without burrs. No pollution and easy operation.
Disadvantage: Unable to cut harder films.
2. Laser cutting machine
Advantages: It can cut high-demand explosion-proof films, privacy films, hardened materials, etc., and has a good cutting effect on complex shapes such as small-angle holes. At the same time, the laser cutting machine does not need to make a knife mold, and can quickly make a good sample.
Disadvantages: high cost, one is about the price of three die-cutting machines. The cutting speed is slow, about five to six hundred slices per hour. Harmful gas and a lot of dense smoke will be generated during cutting, and the edges of cutting are prone to yellow edges and burrs.
