Abstract

PURPOSE:To obtain a skin material having spot patterns on the surface thereof, ensuring that dust or the like adhered thereto is less conspicuous and being useful for automotive interior trim or the like, by a method wherein a mixture comprising at least two kinds of plastic powders is melted in a heated mold to form a film. CONSTITUTION:The mixture of at least two kinds of plastic powders, preferably, having particle diameters of 80-150mum, e.g., plastic powders differing in color, melting temperature or particle size, is thrown into the mold 2 heated to, for example, 150-120 deg.C. After thus heating for a predetermined period of time, preferably, while effecting rotation or the like to form a molten resin layer with a uniform thicknes, the layer is solidified by cooling to obtain the desired skin material. The mold 2 has a desired cavity 1, and is heated by a heater or the like passed through the pipes 4. EFFECT:Suitable for multiple-type small-lot production through changing colors of the components, the ratio of the particle diameters thereof or the like.

てよりその埃等が目立つきらいがある。It is manufactured from a plastic sheet by A-shaped molding or the like, and due to the limitations of the molding method of the plastic sheet, it is forced to be monochromatic, and the color tone tends to be monotonous. Furthermore, plastic has the disadvantage that it is easily charged with static electricity and that dust and the like tend to adhere to it, and when combined with the above-mentioned single color, the dust and the like tend to stand out even more.

The mold 2 is heated in advance to a predetermined temperature (150-200'C), and the glass powder put into the cavity 1 is melted and welded to each other one after another. The excess powder is discharged.

できる。In addition, during molding, the powder components are a mixture of different colors, especially two N with different melting temperatures! Since it is a powder mixture as described above or a powder mixture with different particle sizes, the outermost layer surface of the skin material 6 attached to the mold surface is in a mixed state of two or more powder components as shown in FIG. It will be formed as it is. In other words, the skin material 6 can have a spotted pattern.

The skin material has the characteristic that a surface having a mixed pattern of spots can be formed with good reproducibility. In addition, by changing the color and particle size ratio of each component of the mixture, it has the advantage of being able to easily provide skin materials with different spotted patterns, making it suitable for high-mix, low-volume production. It has a number of possible advantages.
