The invention belongs to the technical field of injection molding, and relates to a hyperspectral display frame hyperspectral traceless injection molding technique. A prepared display frame is high insurface glossiness and free of defects such as melted marks, flow marks, bubbles and shrink marks, the product surface hardness and quality are greatly improved, and the product percent of pass is improved by 20-30%; before injection molding, condensation is conducted at first, then drying treatment and microwave treatment are conducted, and residual internal stress in raw materials can be effectively and completely eliminated; pressure adjusting in the injection molding process is conducted in three stages, shrinkage cavities and recesses are avoided, the flow marks, seam lines and the layering phenomenon are eliminated, the internal stress produced in the product injection molding process and various defects caused in the injection molding process are reduced, and the product percent ofpass, quality and strength are improved; rapid temperature increase and rapid temperature decrease during application are achieved, the speed tends to be uniform, heat energy is fully utilized, heatenergy losses and production cost are reduced, and the product percent of pass is increased; and the spraying procedure is not needed, pollution to the environment is greatly reduced, and the requirements of environment protection and energy conservation are met.
