[0002] Plastics are polymer compounds made of monomers through addition polymerization or condensation polymerization, commonly known as plastics or resins. They can freely change their composition and shape. They are composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants and colorants. In modern life, plastics have a high recycling capacity, so plastics have a very high recycling capacity. The preparation and production of plastics are generally completed using blow molding molds, but for recycled plastics, in order to obtain the matrix flow state of blow molding, they are melted into the required plastic equipment after operations such as slagging and refining. It is one of the important equipment needed for plastic plasticity and reprocessing.
