However, it was difficult to control the amount of resin permeation, and there were cases where the amount of permeation was too small to give gloss, or there was too much resin to cause resin pooling. In particular, there was a case where a white layer with excess resin was formed in a corner portion where pressure was hard to be applied, and a beautiful pattern did not appear.

The die 10 is composed of an upper die 10A and a lower die 10B, and a decorated non-woven fabric (non-woven fabric a) 1 and a plain non-woven fabric (non-woven fabric b) 2 are sequentially set on the lower die 10B and placed on top of this. Place SMC3. After these molding materials are set in the cavity of the mold 10, the mold 10 is closed and pressurized, and these molding materials are heated. As the SMC, the one having the above-mentioned constitution, which is adjusted to have a viscosity of 50,000 poise to 500,000 poise by adjusting the amount of the thickener, is used. Viscosity 50
If it exceeds 10,000 poise, the fluidity becomes poor and it becomes difficult to permeate the non-woven fabric so that not only the formation of the transparent resin layer on the surface of the non-woven fabric a cannot be performed well, but also the non-woven fabric is liable to be broken or bent. If it is less than 50,000 poise, it will not be tack-free and will be difficult to work. That is, if the SMC having a viscosity of less than 50,000 poises is left as it is, it will adhere to the lower table and the film will not be peeled off, the film will not adhere to the work gloves of the worker, and the rigidity as a sheet will be lost. The mold temperature during this pressurization / heating is
It is preferable to set the temperature of the nonwoven fabric a side, that is, the temperature of the lower mold 10B higher than the temperature of the SMC side, that is, the temperature of the upper mold 10A, in order to obtain a more beautiful finish. In particular, it is preferable that the temperature of the mold 10B on the nonwoven fabric a side is 140 ° C to 160 ° C and the temperature of the upper mold 10A side is 120 ° C to 140 ° C. Further, the pressing force of the mold 10 is 30 kgf / cm 2 to 100.
It is suitable to use kgf / cm 2 .
