Do I need a lens protector iPhone?
Everyone knows the importance of mobile phone film, it can effectively prevent screen broken screen. But few people pay attention to the lens film, leaving the phone lens exposed to danger.
Many people do not accept phone back lens glass film because they are afraid that after attaching the film, the picture taken will not be able to show the original camera's shooting effect, and it will appear blurry and distorted. It is true that there are many low-quality lens films on the market, and after they are attached, there will be color distortion and even glare. However, if a high-aluminum mobile phone stickers glass film is added, this problem can be effectively avoided. Because the high-alumina glass has high transparency, it can basically fully present the real scene of the original picture, and the color and light will only slightly change, which is almost the same as the original shooting effect.
The current high-quality phone camera sticker protector will use a five-layer structure to protect the phone lens in all directions. Although a high-quality lens film has a five-layer structure, today's advanced technology can integrate these five layers together, so the general lens film is only about 0.2 mm, which is very light and thin.
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.
