to injection molding. The injection molding ARBURG ALLROUNDER; Model 370U, (70
closing force) with four temperature zones on the cylinder was used to produce the tensile specimens. The nozzle temperature was set at 160 oC and the others zones were kept at the same temperature. The mold surface temperature was 50 oC and the cooling time was 25 s. Filling pressure and holding pressure were 130 and 70 MPa, respectively.
