Pre-drying :

Nylon being hygroscopic material, it is advised to predry the material in vacuum / air circulated ovens at 100/80°C for 2 - 4 hrs to avoid silver streaks and improve surface finish. For natural colours predry the material at lower temperature to avoid discolouration.

Injection pressure : The above given values or as sufficient to fill cavities.

Use of shut-off nozzle is recommended to avoid drooling.

Conditioning : It is advised to condition components 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 during further assemply.

Above parameters are only guidelines and exact process conditions have to be established for each machine/mould depending upon equipment capacity, part geometry. It is given in good faith and no warrant is attached.
