  • Patent number: 4938904
    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.

  • Patent number: 4822438
    Abstract: A process for insulating a rotational casting mold for use in a casting process for making a substantially even thickness fascia. The fascia 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.
