作業に手数を要し。For example, when painting the exterior parts of an automobile bumper made of urethane foam, there are parts that do not require painting for various reasons. Widely used methods have been to cover areas that do not need to be painted using a metal masking mold, or to completely cover areas that do not need to be painted using paper tape. The boundary line with the painted area cannot be clearly defined, resulting in a significant loss of appearance.Furthermore, after the painting process, the exterior product moves to the next baking and drying process, but in this process, the exterior Due to the large difference in thermal expansion coefficient between the product and the metal masking mold, curved deformation occurs on the exterior product, and this type of painting process mainly adopts the conveyor production method. Therefore, a large number of metal masking molds were temporarily required, and the cost of these metal masking molds could not be ignored, and there remained a problem in this respect as well. In addition, in the latter method, in order to make the painting boundary line clear, 10~20 rxm is placed near the boundary line.
A wide tape is pasted on the shield, and the other non-painted areas are covered with wide tape or covering paper, and this is fixed with tape, etc., but this method does not require the application of tape or other covering materials. It takes a lot of effort.
またテープ、被覆紙の再利用ができず、ために材料費が
嵩むなどの欠点が残った。In addition, the tape and covering paper could not be reused, resulting in increased material costs.

用いて具体的に説明する。It also provides a partial coating method using the overmask method for 1° plastic molded products that does not cause curvature deformation of the molded product even during the baking and drying process. Paint the molded product described in t using a plastic masking material that has a coefficient of thermal expansion similar to that of the molded product described in L and has an inner wall surface that approximately matches the external shape of the parts of the molded product that do not require painting. It is characterized in that the masking material is applied to unnecessary parts, and the entire length is fixed with tape over the edge of the masking material and the molded product. Next, an example of this invention as a plastic molded product will be described. This will be explained in detail using drawings.

ている。FIG. 1 shows an exterior product made of urethane resin for an automobile bumper, which is a plastic molded product according to the present invention, and FIG. 2 is an enlarged end view taken along the line AA in FIG. 1. This exterior product (1) has areas (2) (2) that require painting and a convex area (3) that extends in the longitudinal direction at approximately the center of the exterior product, and this area that does not require painting. (3) is the relevant part (
The painted area (2) is covered with a plastic masking material (4) that has an inner wall surface that approximately matches the external shape of the painted area (2).
) and areas that do not require painting (3), a tape (6) is pasted along the entire length of the masking material (4) and part of the exterior part, and the tape (6) A clear painting boundary line (5) is displayed at the adhesive edge with the product, and this tape (6) firmly fixes the masking material (4).
