How to dry bake car film Car film baking technique skills Car film baking film common technique skil

1. The practice of combining wet and dry stereotype:

1) The combination of dry and wet setting method is a method used when it is impossible to determine whether the consistency of the film and the curvature of the glass is consistent after dry baking.

2) After the dry baking is completed, the film is lifted, the installation liquid is evenly sprayed on the hand excitation glass, and then the film is put down, and the water is squeezed out with a plastic scraper.

3) When you encounter residual bubbles, bake them flat with the wet roasting method.

2. The practice of stretching and shaping:

1) Clean the glass with a scraper first, and blow dry the residual moisture on the surface of the glass with a heat gun.

2) Use a wet paper towel to draw a wet line about 3 cm wide in the middle of the glass (for fixing the film).

3) Spread the roughly cut film on the glass surface, leaving 5-8cm more up and down.

4) Cut a few small holes on the upper and lower sides of the film with bubbles, when baking the film, lift the film by hand, at an angle of about 15 degrees with the glass, pull it down hard, rotate the baking gun evenly, from top to bottom, and observe the degree of film shrinkage with your eyes.

5) Pay attention to the temperature of the baking gun and the degree of heating of the film when baking the film, adjust the temperature with distance or speed, and make the bubbles evenly heated when baking the bubbles.

6) After baking, cut off the remaining ingredients, the edge can be properly baked, and leave the baking gun for 1-2 seconds to shrink the membrane edge.

7) You can also spray water again to wet roast, if there are residual bubbles, bake flat according to the method of wet roasting.

3. The operation method of the internal irrigation and shaping method:

1) Clean the glass first, and evenly spray the installation solution on the outer surface of the glass.

2) Place the roughly cut film on the glass and position it with a plastic scraper. Divide the bubbles evenly.

3) The first third of the bubbles is the need to bubble caused by the wide brother belt of the membrane, do not do any treatment, bake lightly at the third of the bubble, and make a knot.

4) On the mouth of the bubble, use a heat gun to pour between the film and the glass, when the edge of the bubble is attached to the glass (you can press and hold both sides of the bubble with your hands), quickly heat the bubble with a heat gun, and use a plastic scraper to quickly scrape the bubble flat.

Generally, junior technicians can only apply film to the side windows, while only intermediate and senior technicians can apply film to the front windshield with a large curvature.

Before the film, it is necessary to check whether the installation of the window glass is intact and the integrity of the car glass to ensure that the subsequent film work can operate normally.

Be sure to cover the necessary parts of the car before applying the film to prevent liquid from penetrating. Sprayed cleaning fluids and lubricating fluids can affect trim parts such as automotive electronics and interior seats.

Wash the interior and exterior surfaces of the windows before applying the film (focusing on the interior surfaces and glass sealant areas). This is mainly to eliminate the dirt or other object construction quality problems between the film and the window glass after the film, and ensure that the film and glass can be perfectly combined.

The membrane is pre-cut. Use a ruler to measure the size of the front and rear windshields, and cut the film according to the measured size. (The professional rubber film mechanism is through the computer, and the computer is tailored according to the model).

Spray the installation fluid. Dust spots can be avoided and corrosion at the edges can be reduced, resulting in the desired viscosity and better application results.

Dry roasting, wet roasting shaping. The film is dry-roasted first so that the film can be fully pre-shrunk. In order to further improve the adhesion of the heat insulation film, it is also necessary to wet bake and shape the heat insulation film.

Extrusion of the installation fluid: In the process of using the wiper to remove the installation fluid, try to scrape the installation fluid between the heat insulation film and the window glass, which can reduce the drying time of the heat insulation film and obtain a better bonding effect, overall performance and visual effect.

Check after sticking. "Three looks and one attention": look at the entire heat insulation film to see if there is any dust and bubbles, see whether the corners are firmly glued, and sit in the car to see if there are any places that affect the line of sight (especially the front windshield and side windshield). After the film, it is recommended not to raise or lower the glass arbitrarily within 48 hours.

The most important thing to pay attention to when applying the film is the use of hair dryer, if you blow this place for a long time, it will cause the glass to crack due to uneven heating. Therefore, the film should find those professional authorized stores, so that the quality of the film will be ***, and the danger of glass cracking can be avoided.

Also, the car film is best in rainy weather, and when it is pasted on rainy days, there is very little dust in the air, which has certain benefits for aesthetics.
