PACKAGING & PRE-DRYING
Synergy's Synlon (Nylon 6 & 66) is packed at maximum moisture content of 0.2% in moisture-proof, lined packaging. However Nylon being hygroscopic, it is advisable to dry the material at 100-120 degree centigrade for 2-4 hours. Natural and lighter shade material may be dried at lesser temp. and lesser duration to avoid discoloration, brittleness due to over heating. Then need for drying the material is evident by the formation of bubbles or foam in the melt, excessive drooling from the nozzle, or streaks in the molded parts.
PROCESSING RECOMMENDATIONS
Synergy's Synlon (Nylon 6 & 66) should be injected at fast injection speeds, to prevent premature crystallization. Low to medium injection pressures is recommended. Faster injection speeds and medium injection pressures provide a longer material flow path in the mold, better packing, good surface appearance, and low molded in stresses.
The Holding or packing pressure should be about 50 to 65% of the injection pressure. The holding pressure should be optimized to effectively control sink marks and flashing. Optimum extruder speed and back pressure must be used to ensure a uniform melt and shot size consistency. Sufficient back pressure ensures homegenous melt formation and elimination of gas voids in the melt. Use of shut-off nozzle is recommended to avoid drooling.
Conditioning : It is advised to condition in hot water at 80-100 Deg. C for 2-4 hrs. depending upon the component thickness and as required by the subsequent process also to release internal stresses if any to avoid breakage druing further assembly.
