一般に多く用いられている。However, on the other hand, it has drawbacks such as a cheap feel, a cold feel, and the appearance of fakes, and there has been a strong demand for it to have decorative properties and a soft feel. Conventionally, various studies have been made to obtain composites with functions that satisfy these demands, but it has been found that a single material can maintain free formability and strength while improving the surface properties of the above-mentioned drawbacks. It is difficult to have the same properties, and at present, laminates made of a combination of multiple materials with different functions are commonly used.

合の保持性には限界があり問題であった。(Problems to be Solved by the Invention) Although the above-described conventional methods can produce a laminate without wrinkles or tears in the skin material even for molded products with considerably complex shapes, they are not necessarily sufficient. Furthermore, there is a problem in that there is a limit to the ability to maintain the good texture of the skin material before and after molding.

A textured skin material is produced by melting on the mold surface to form a molten film, which is then cooled and solidified in the first step.

This is a method in which a core material molten resin is supplied between the material molding mold and the other mold, and both molds are closed to complete the molding of the core material resin and obtain a laminate in which the skin material is integrated. .

Immediately, the integrated container and mold are rotated and revolved by a two-axis rotation device, and the powder αυ is transferred to the mold (Fig. 1).
2) The powder is supplied into the container and adhered to the surface of the mold having an uneven shape, and after stopping the rotation, the mold is removed from the container, and the adhering powder is heat-treated to form a molded film, which is then cooled to form a skin. (Produce one piece (Figure 2).

転写度を保持又は向上させる効果を有する。Next, the powder molding mold (2) is transferred to the core material coloring stage while retaining the skin material (1z), and the mold base (8) is transferred to the core material coloring stage.
The lower mold for forming the core material (4) is then raised to form the lower mold for forming the core material (4) and the core material. After closing the molding earthen mold (5), core material molten resin is supplied between the skin material (121) on the lower mold and the upper mold (6) through the resin passage (6), and the core material resin is molded. At the same time, while the skin material a'a is not closed, supply the core material molten resin between the skin material α and the core material molding upper mold (5) through the resin passage (6). Finally, as shown in FIG. 8), both molds are closed to complete the molding of the core resin and obtain a laminate α9 integrated with the skin material α3. (Figure 4) After the molding is completed, lower the lower mold to open the mold and take out the product. By using this method, powder molding mold (2)
Since the skin material (12+) to which the uneven pattern has been transferred is used for molding the core resin while being held in the mold, the uneven pattern does not collapse during molding of the core resin, resulting in an excellent texture. Furthermore, if a method is used in which the core material molten resin is supplied while the pair of core material molding molds (4) and (5) are not closed, the material can be mixed with the molds closed. Compared to the feeding method, the shear rate at the contact surface of the skin material during filling and shaping of the core material molten resin is lower, the force that causes displacement of the skin material is weaker, and the mold clamping force when both molds are closed is lower. This has the effect of maintaining or improving the transfer degree of the uneven pattern.

よい。In this example, a method was shown in which a special powder molding mold for core material was used as the lower mold and the core material molten resin was supplied from a resin passage provided in the upper mold, but the method is not limited to this. The molten resin supply nose may be inserted between the upper and lower molds to supply the molten material, and after supplying, the supply nose may be retreated out of the system and the upper and lower molds may be closed for molding. However, a powder molding mold may be used as the upper mold, and the core molten resin may be supplied with a resin passage provided in the lower mold.Furthermore, a horizontal mold clamping molding apparatus may be used.

できる。Furthermore, as a mold for forming the core material, as in this example (No. 8
(See Figure 4), it may be a type of mold in which both molds slide and close, or it can be used for normal injection molding only when the core molten resin is supplied after closing one mold. It may also be a butt type mold. When using a type of mold that slides and closes, by setting the clearance of the sliding surfaces of both molds to a value approximately equal to the thickness of the skin material, the ends of the molded product can be closed as shown in Figure 5. After molding, the excess skin material (LIEI) is folded back to the back of the molded product.
It is also possible to completely cover the end portion of the molded product with a skin material.

After the layer is interposed between the skin material and the core resin, the core material molten resin may be supplied and molded. Furthermore, when both are directly heat-fused, an intermediate layer may be interposed.
