Embodiment 1
[0027] First dry the PC resin in a dryer for 3-4 hours at a drying temperature of 110°C-130°C, then put 90% of the PC resin, 5% of the stabilizer and 5% of the filler into the high-speed mixer for mixing , and then put the stirred raw materials into the twin-screw extruder, knead and extrude under the condition of 240-260 ° C, cool and granulate for preparation, put the extruded raw materials into the molding tank 2 of the injection molding machine, and use the moving mold 3 for molding, the serrated surface at the bottom of the movable mold 3 makes the surface of the injection molded part form a corresponding serrated surface, and finally a layer of AG coating is applied on the serrated surface by heat shrinking process.
Embodiment 2
[0029] First dry the PC resin in a dryer for 3-4 hours at a drying temperature of 110°C-130°C, then put 90% of the PC resin, 5% of the stabilizer and 5% of the filler into the high-speed mixer for mixing , and then put the stirred raw materials into the twin-screw extruder, knead and extrude under the condition of 240-260 ° C, cool and granulate for preparation, put the extruded raw materials into the molding tank 2 of the injection molding machine, use the bottom surface without The movable mold 3 of the serrated surface is formed, and finally a layer of AG coating is pasted on the serrated surface by heat shrinking process.
Embodiment 3
[0031] First dry the PC resin in a dryer for 3-4 hours at a drying temperature of 110°C-130°C, then put 95% of the PC resin, 2% of the stabilizer and 3% of the filler into the high-speed mixer for mixing , and then put the stirred raw materials into the twin-screw extruder, knead and extrude under the condition of 240-260 ° C, cool and granulate for preparation, put the extruded raw materials into the molding tank 2 of the injection molding machine, and use the moving mold 3 for molding, the serrated surface at the bottom of the movable mold 3 makes the surface of the injection molded part form a corresponding serrated surface, and finally a layer of AG coating is applied on the serrated surface by heat shrinking process.
[0032] To sum up, Example 1 is the best trial plan. Through molding with this kind of ratio, the quality of injection molded parts is higher, and through the effect of serrated surface and AG coating, the anti-glare effect of injection molded parts is good. ...
