Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to painting technology, and relates to a method for producing a multi-color rim including a metallic color, which is coated in multiple colors by laminated coating.

[Conventional technology]

In recent years, lamp parts for automobiles and other vehicles are often finished in multiple colors, including chrome plating, due to design requirements.
As shown in Fig. 6, the surface of the molded synthetic resin rim 1 is painted one color at a time, including chrome plating, so that the black painted part 2, the red painted part 3, and the chrome plated part 4 are painted separately. I was getting multiple colors.

That is, a black painted part 2, a red painted part 3, and a chrome plated part 4.
In the case of a rim as shown in Figure 6, which is painted in three different colors, (1) First, chrome plating is applied to both the front and back surfaces of rim 1.

(2) Next, the portion to be left as the chrome plated portion 4 and the portion to be the red painted portion 3 are masked and painted black to form the black painted portion 1.

(3) Furthermore, while leaving the masking on the chrome plated part 4, peel off the masking corresponding to the red painted part 3, apply new masking to the black painted part 2, apply red paint, and then apply red paint. Painting is carried out through a variety of processes including metal plating processes such as forming part 3.

[Problem to be solved by the invention]

Therefore, if there are many steps to apply the paint, there is a problem in that the cost of plating increases and the production cost increases.

The present invention was devised in view of the above problem, and is capable of providing a multi-colored rim including a metal-plated portion such as chrome plating at a relatively low cost. The purpose is to propose a method for manufacturing rims.

[Means to solve the problem]

The method for manufacturing a multi-tone rim including metallic tone according to the present invention includes:
After a rim molded from synthetic resin is molded using a resin molding material having a first color, a part of the surface of the rim molded product is coated with a paint comprising a second color, and then a paint comprising a second color is applied to a part of the surface of the rim molded product. The gist of this method is to apply a paint having a third color in a layered manner to a part of the surface of the colored paint film, so that the painted portions appear in a plurality of tones.

Furthermore, the metal tone can be obtained by: (1) Generally painting the second or third color with a chrome tone paint.

(2) A rim is molded by mixing metal powder such as chromium or nickel into a resin molding material to form a metal-colored part.

(3) The second color tone can be formed by partially forming a film by ROM plating, etc.

[Effect]

The above-mentioned multi-colored rims are first molded from synthetic resin and then molded from a resin molding material with the first color, so the base color of the rim molded product itself must be one of the finishing colors. It is possible to reduce the number of steps needed to apply color. By mixing metal powder such as chromium or nickel into the resin molding material and molding the rim, the first color can be made into a metal-toned portion.

Further, by applying the second or third color by general coating with a chrome tone, the plating process can be omitted.

Even when the second or third color is applied by plating, the film can be formed by partial plating, and the cost of plating materials can be reduced.
