Abstract

The invention discloses a forming method of a high-gloss no-weld line light guide plate. The forming method is characterized by comprising the following steps: (1) setting an automatic feeding system to automatically feed injection molding master batch so as to load materials; (2) setting an injection molding machine which is provided with a temperature control system to control the temperature of an injection mold, and performing injection molding on the molten injection molding master batch supplied in the step (1) to obtain a formed piece under the condition that the mold temperature is 30-90 DEG C and the melt temperature is 210-280 DEG C; (3) setting a fly-cutter milling system to mill the surface of the forming piece under the condition that the rotating speed is 2000r / min and the feeding speed is 20mm / min; (4) setting an optical film and hot-pressing the optical film on the upper surface of the injection molding piece after milling; and (5) setting a punching system for performing punch forming on the injection molding piece on which the optical film is pressed to obtain the high-gloss no-weld line light guide plate. The invention further discloses the high-gloss no-weld line light guide plate prepared by using the method.

Description

technical field [0001] The invention relates to the field of light guide plate molding, in particular to a molding method of a high-gloss non-melting mark light guide plate, and a high-gloss non-melting mark light guide plate product prepared by the method. Background technique [0002] Mold is an extremely important and indispensable special basic process equipment in industrial production.
