Front shell of flat-panel TV and manufacturing method thereof

Abstract

The invention discloses a flat television front shell and a manufacture method of the flat television front shell. The material of the flat television front shell includes 90-99% of ABS (Alkyl Benzo Sulfonate), 0.1-5% of aluminum metal powder and 0.1-5% of antioxidant. The method comprises the steps of: pelletizing the materials to form mixed plastic material particles to dry for 2-4 hours at 90 DEG C; then adding the mixed plastic material particles into an injection molding machine to inject; setting the temperature of a hot runner of the injection molding machine to be 260 DEG C, orderly setting the temperature of a gun barrel to be 250 DEG C, 245 DEG C, 240 DEG C, 230 DEG C and 220 DEG C; heating a fixed die surface of a die to be over 130 DEG C and then carrying out glue injection and pressure preservation, cooling the die to be 60-70 DEG C and forming the flat television front shell after die sinking. The flat television front shell adopts the ABS plastic material mixed with the aluminum metal powder; the plastic material is utilized for carrying out injection molding of the die; the metallic effect of the flat television front shell is achieved; and the cost of the product is reduced, and the freedom of a product design and the manufacturing possibility are greatly improved.

Description

technical field [0001] The invention relates to the technical field of televisions, in particular to a front shell of a flat-panel television and a manufacturing method thereof. Background technique [0002] With the development of LCD TV technology, consumers not only have higher and higher requirements for product quality, but also have more and more diverse requirements for product appearance. The traditional appearance of traditional LCD TVs is generally black. In recent years, in order to improve product quality, some LCD TV panels are made of aluminum alloy metal or sprayed with metal effect paint to achieve metallic appearance and color effects such as silver white (gray). Metal materials are expensive and the manufacturing process is relatively complicated, which greatly limits its application and promotion. However, spraying metallic effect paint requires special spraying workshops and equipment, which results in low spraying efficiency and serious environmental po...
