The invention relates to a process for producing shaping plates by using waste paper, plates and waste plastics. The process includes that subjecting the waste paper and plates to purifying pretreatment prior to pulping; concentrating pulp subjected to size degradation to 4.0+ / -0.5% in concentration before allowing the same to enter a pulp chest, delivering the pulp to a pulping machine through a pulp pump, delivering ground pulp into a full pulp chest prior to delivering the same to a mix pulp chest through the pulp pump; pulverizing the waste plastics through a pulverizer, separating the ground plastic through a separating screen, delivering plastic particles conforming to grinding standard to a grinding machine for grinding and refining prior to delivering to the mix pulp after filamentation; mixing paper pulp and plastic pulp prior to purifying through a slag separator, forming, splitting, drying, cooling, releasing, edge cutting, mechanical processing and finishing, testing, vacuum packaging and vacuum packaging and warehousing. The process is simple in process path, and special equipment can be partially added by utilizing existing equipment, so that equipment investment is less, and commercial value of products is high.
