Glass Filled Nylon (Polyamide 6) Composites is a hygroscopic material where it is very sensitive to moisture which is an important factor to be considered during material pre-selection, parts design, mechanical performance prediction, testing and evaluation process. The effect of moisture can be a major factor in products and parts evaluation that were exposed to different weather conditions due to changing in seasons or geographic locations. Due to this effect of moisture absorption in uncontrolled condition, rejection % increased from 3% to 20% due to inconsistent of testing results during in process inspection. This also caused some of the production lot to be quarantined until further verification. This resulted loss and reduced of the profit of the company as well as wastage of material and resources. The research focused on process control of conditioning the nylon parts and components after molded before proceeding with testing and evaluation. Post Conditioning machine was developed for quantify the optimize process control of Glass Filled Nylon (Polyamide 6) Composites parts. These process control covered a wide range for 3 process parameters for conditioning; temperature (from 20 to 80-degree C), relative humidity (from 30% to 80% RH) and time (unlimited variables control). The variation of these parameters may result in significantly different moisture absorption rates, equilibrium levels and mechanical properties.
