Melt Temperature: Melt Temperature: Nylene® PA6 melts at 428°F, (220°C) actual melt temperatures of 440-560°F (227-293°C) are permissible, depending on residence time and shot size.
Mold Temperature: 120-200°F (49-93°C), highly filled grades require 180-200°F (82-93°C) to obtain the best overall surface appearance, higher temperatures will increase crystallinity.
Residence Time: should not exceed 6 minutes if possible, less with higher melt temperatures
Shot Size: should be between 25-75% of barrel capacity.
Fill Rate: fast fill rates are suggested for best surface appearance.
Regrind Level: typically no more than 25% is recommended, with higher levels possible for unfilled grades depending on the end use requirements. Make certain regrind is properly dried to virgin moisture levels.
Drying Temperature: 150-180°F (66-82°C) for 2-4 hours, Nylene® PA6 should be dried to less than 0.20% moisture for optimum performance. Drying longer than 4 hours or at higher temperatures may cause discoloration of the polymer or adversely affect important physical properties.
Nylene NX1440 is a nucleated medium viscosity, fast cycle molding resin. Parts molded from NX1440 have better dimensional stability at moisture equilibrium than parts molded from other nylon Parts molded have better dimensional stability at moisture equilibrium than parts molded from conventional nylon. Crystallization initiators provide fast molding cycles through rapid melt set-up. Most useful for applications requiring greater stiffness and a higher heat distortion temperature.
