[0002] Plastic, often referred to as plastics, is a widely used synthetic material mainly composed of organic or inorganic elements such as carbon, oxygen, hydrogen, and nitrogen. The finished products of this material are in a molten liquid state during the manufacturing process, can be heated and melted, pressurized and flowed, and solidify into various shapes after cooling. Plastics have good electrical insulation, arc resistance, and characteristics of heat preservation, sound insulation, sound absorption, and vibration absorption. The application fields of plastics include household appliances, automobiles, mobile phones, medical devices, etc. With its plasticity and cost advantages, it is gradually replacing multiple traditional metal parts. When plastic raw materials are processed, they need to be melted, but the traditional heating method is usually from the outside to the inside, so the heat fault that appears will cause uneven melting degrees inside and outside, resulting in a reduction in melting efficiency, and the voids between raw materials are easily wrapped during the melting process to form cavities. Therefore, this application provides a plastic raw material melting device. Summary of the Utility Model
