PURPOSE:To improve processability and cost of production and to attempt to improve strength of the molding by supplying directly wooden fibers containing a binder into a mold and by compressively molding it. CONSTITUTION:Wooden fibers M3 containing a binder are compressed and molded in a top force 41 and a bottom force 42 heated at 180-220 deg.C by means of a hot plate 51. In this operation, when the top force 41 is at a few mm before the bottom dead point, generated gas is evacuated by sucking it from a gas evacuating hole 52 through a sucking pipe 52 and a valve 54. The fibers do not thereby get entangled and are kept into scattered pieces so that they have good fluidity and no decrease in the thickness and no crack takes place in even deep drawing parts 55. While evacuating air from the evacuating hole 52, the mold is opened and a wooden molding M4 is sucked onto the top force 41. The evacuation is then released by switching the valve 54 and a door trim base plate consisting of the wooden molding M4 having a deep drawing part 55 which is an arm rest and without any fault can be obtained. |
