Many customers have such questions when choosing silent tires:
- “Why is there less silent sponge in your silent tires than other brands, but the effect is better than theirs?”
- “Is your silent sponge factory-provided or upgraded later?”
- “Will the silent sponge fall off?”
Today, let’s go to the tire factory warehouse of tiptop laser service project to check in and visit the entire production process of silent tires.
Entering the tire factory warehouse, what comes into view is a sea of tires. In the warehouse of about 3,000 square meters, various types of tires are neatly placed. And in an inconspicuous corner, there are several mysterious devices. This equipment explains all the secrets of silent tires for us. Now let’s uncover the secret of tire silence.
When we first saw this machine, we all thought it was an experimental cabin. But in fact, it is a tire inner wall cleaning machine, but unlike the previous high-pressure water gun cleaning, this machine uses laser to clean tires.
What is the principle? In fact, experienced people know that tires made of rubber will have some smell, and the source of this smell is the original rubber layer of the tire. This rubber layer will affect the adhesion of the glue inside the tire. The simple high-pressure water gun cleaning method in the past cannot be completely cleaned, and it will also damage the surface structure inside the tire. The so-called laser cleaning technology is to use the high temperature of the laser to burn the surface inside the tire, eliminate the gelatin layer, and make the surface smoother.
After the laser cleaning is completed, it can be clearly seen that the cleaned surface is significantly different from the uncleaned surface. You can clearly feel that the cleaned surface feels smoother and more delicate by touching it with your hands.
Then you can directly see the core technology of the silent tire-sticking cotton. In fact, compared with other tires, the difference of the silent tire is only that there is an extra layer of silent cotton, which plays a role in shock absorption and sound absorption. It sounds simple, but the core of this step depends on three points: silent cotton, glue and sticking method.
The quality of the silent cotton is directly related to the silent effect. In fact, different brands use different silent sponges. This core technology is generally confidential and belongs to technical patents. Another is glue. The quality of glue directly affects the pasting effect of silent sponges and whether it is easy to fall off. Good glue is also a patented technology, which can quickly bond silent sponges and tires. The editor tested that after sticking it on, it really couldn’t be pulled off by manpower. Finally, it is the pasting process. Many people may think that it is just to apply glue to the surface and then stick it on. In fact, it is not the case. The glue is a patented formula, which is invaluable, and the comprehensive application is not necessarily the best. It may cause glue overflow and affect the bonding effect.
Tire manufacturers use original laser positioning technology and interval pasting technology. Professional technicians apply glue and paste according to the positioning of the laser. While keeping the silent sponge firm, the effective space inside the tire is retained to the greatest extent, making driving more stable. This is the secret weapon of tire silence!
