ABSTRACT:
A process for making a substantially even thickness fascia part. The fascia part is prepared by placement of a plastic powdered material into an enclosed mold, heating and agitating the mold for distributing the plastic powder on the mold surfaces to provide a substantially even thickness fascia part on the molding surface. The mold includes first mold surfaces for defining critical portions of the mold which correspond to the desired portions of the mold for forming the finished shape of the part by melting of the plastic powder to a uniform film along the surface. The mold also includes second mold surfaces defining non-critical portions of the mold where it is undesirable for plastic filming to occur. The process for making a fascia part includes cutting a plurality of sections of insulating material to fit the non-critical portions of the mold, coating the non-critical portions of the mold with a heat resistant bonding material before assembling the cut sections onto the non-critical portions followed by curing of the bonding material and thereafter releasing a plastic powder into the mold. The mold is then heated to a temperature for melting the plastic powder material. The mold is rotationally agitated for distributing the plastic material onto critical molding surfaces. The plastic is prevented from covering the non-critical surfaces by heat insulation of these surfaces.
