Two-tone baked paint is a unique parts painting technique that is gradually gaining attention in the automotive and custom parts fields. By covering the part surface with two different colored paints and baking to form an excellent appearance. This technology can give parts a unique visual effect and higher durability, enhancing the connotation and value of the product. This article will explain in detail the steps and skills to achieve two-tone baked paint, as well as the advantages and precautions of this technology.

The Significance of Two-Tone Baked Paint

Compared with single color painting, two-tone baked paint can make the part surface show two different colors, achieving a richer sense of visual hierarchy. This not only makes the product appearance more stylish and technological, but also meets more consumers' personalized preferences. In addition, two-tone baked paint can also serve as a business marketing tool, attracting eyeballs and enhancing its value through unique painting.


Implementation Methods of Two-Tone Baked Paint

1. Segmented Spraying Method

Spray different areas of the parts with different colors according to the color requirements, and use baffles or shields for relevant segmentation. This process is operated before the paint dries, which requires precise shielding and spraying control technology.


2. Multi-step Baking Paint Method

First spray one color on the workpiece surface and bake once. After curing, mask the first sprayed surface, spray the second color and bake again. This requires strict control of the baking parameters.


3. Gradient Color Spraying Method

Use gradient colors in the intersection of the two colors to achieve a smooth and natural transition. This requires dedicated gradient color spraying technology.


4. Coding Technology

Coding equipment can directly spray patterns of two or more colors on the part surface. This technology is flexible and convenient to operate.


5. Film Covering Method

Cover different colored films on the cured base color to achieve a two-tone effect. This requires high-quality films with good surface processing.


How to Achieve Two-Tone Baked Paint

Realizing two-tone baked paint requires a series of careful steps and professional techniques. The specific implementation process is as follows:

1. Design Scheme and Color Selection

Before starting a two-tone baked paint project, you first need to clarify your design plan and choose suitable color combinations. You can choose colors that form a striking contrast, or more harmonious tones. It is important to ensure that the design scheme matches the purpose and style of the parts and adds unique charm.

2. Surface Preparation and Treatment

Before spraying, it must be ensured that the part surface is clean, flat and free of any impurities. Thoroughly clean the parts, removing oil, dirt and old paint. Gently sand the part surface with appropriate sandpaper to ensure the paint layer adheres more firmly.

Shielding and Protection

Before spraying, it is necessary to carefully shield and protect each area of the parts to prevent unnecessary overspray. Use professional masking tape and plastic film to protect areas that do not need to be painted, ensuring that the paint is only sprayed in the designated area.

3. Apply Primer

The first step is to apply primer. Choose one of the colors and spray evenly on the part surface, ensuring a thin and uniform coating. Use high-quality spray equipment and techniques to ensure optimal results.

4. Bake Primer

After applying the primer, the parts need to be placed in a professional baking room to allow the paint layer to dry and cure quickly. The baking time and temperature should be determined according to the paint used and the material of the parts to ensure the coating achieves the best effect.

5. Mask the First Sprayed Area

After coating the primer, it is necessary to mask and protect the completed areas for spraying the second color. Use tape and plastic film to protect the primer, ensuring that the new paint only covers the designated area.

6. Apply the Second Color Paint

After the first sprayed area is masked, you can start spraying the second color paint. Use the same method as coating the primer to spray the second color evenly. Ensure a smooth and natural transition, avoiding unclear color boundaries.

7. Bake the Second Color Paint

Similar to the first color paint, the second color paint also needs to be baked to ensure coating curing and durability. Place the parts in the baking room and bake according to the manufacturer's recommendations for the paint.

8. Apply Clear Coat

After all spraying is complete, applying a layer of high-quality clear coat is critical to ensuring the durability of the two-tone baked paint. Clear coat not only protects the painted surface, but also adds gloss and depth.

9. Fine Grinding and Polishing

The final step is fine grinding and polishing of the parts. Remove possible flaws and sanding marks to add a smoother effect to the two-tone baked paint surface.

Quality Control Points

  • The adhesion between color layers cannot be too high or too low, otherwise it will easily peel off or mix colors.

  • The transition of the color boundary must be smooth and natural to prevent obvious boundaries.

  • The baking equipment needs to precisely control the time and temperature parameters.

  • The two-color layers should be equally thick to prevent uneven appearance.

  • The color difference needs to be controlled within an acceptable range.

In summary, two-tone baked paint can greatly enhance the appearance and added value of products. By choosing a suitable two-tone baked paint method according to the product characteristics and controlling key quality parameters, the desired two-tone baked paint effect can be obtained.
