Other Processing
Injection Molding
Standard reciprocating screw injection molding machines with a high compression screw (minimum 3:1 and preferably 4:1) and low back pressure (0.35 Mpa/50 PSI) are favored. Using a low compression screw (I.E. general purpose 2:1 compression ratio) can result in unmelted particles and poor melt homogeneity. Using a high back pressure to make up for a low compression ratio may lead to excessive shear heating and deterioration of the material.
Use a slow injection speed until material passes through the gate.
Melt Temperature: Preferred range 180-195℃ (~356-~383℉). Melt temperature should never exceed 230℃ (450℉).
Mold Surface Temperature: Preferred range 80-105℃ especially with wall thickness less than 1.5 mm (0.060 in.). May require mold temperature as high as 120℃ (250℉) to reproduce mold surface or to assure minimal molded in stress. In general, mold surface temperatures lower than 82℃ (180℉) may produce a hazy surface or a surface with flow lines, pits and other included defects.
