(3), will by the mixture in step (2) and glass fibre 15~25min of preplasticizing in twin-roll plastic mixing mill at 150 DEG C
In the mixture injection injection mold of preplasticizing, 15~20min of hot pressing under the conditions of 50~70Mpa, 220~260 DEG C；
(4) and then by material grain it is expelled to by parallel dual-screw extruding machine in mould, injection temperature is 190~230 DEG C, pressure is
80~120Mpa, screw speed is 160~210r/min, is stripped after cooling, produces the high-strength resistant modeling of the LCD TV
Expect frame.
