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. moisture levels.
Cylinder temperatures should be in the 435 – 525ºF range. Designed for excellent cold temperature impact. High impact modified nylon 6 suitable for both molding and extrusion. Outstanding high strength and high cold temperature impact. Parts molded from 743 have excellent impact strength right out of the mold without post conditioning.
