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.

Melt Temperature: Preferred range 182-199℃ (360-390℉). Melt temperature should never exceed 230℃ (450℉).

Mold Surface Temperature: Preferred range 82-93℃ (180-200℉) 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. Wall thickness greater than 3mm (1/8 in.) may use a cooler (65℃/150℉) mold surface temperature and wall thickness over 6mm (1/4 in.) may use a cold mold surface down to 25℃ (80℉). In general, mold surface temperatures lower than 82℃ (180℉) may hinder weld line formation and produce a hazy surface or a surface with flow lines, pits and other included defects that can hinder part performance.
