ABSTRACT:
The invention is to apparatus and method for a plasticizing batch process used in manufacturing building materials such as sheet goods, roofing shingles, and various sizes of dimensional lumber products. Recycled waste plastics and other not plastic materials are used in a batch process to plasticize the waste materials into a mixture used in molding various products. A intensive mixture mixes and plasticizes the waste materials of a predetermined weight until the plasticized mixture reaches a predetermine temperature. The material is then expelled to a material mover to dispense the plasticized material by weight to molds in which the plasticized material is pressed to form various products.
