The Challenge
The client was spray-painting automotive interior trim parts to achieve a metallic finish, resulting in high VOC emissions, 20% reject rate from paint defects, and long production cycle times.
Our Solution
MHK Color developed a custom metallic masterbatch using aluminum flake pigment in a PA carrier matched to the client's base polymer. The formulation achieved the same visual effect as spray painting in a single injection molding step, eliminating the painting process entirely.
Results Achieved
Zero VOC emissions achieved. Reject rate dropped from 20% to under 2%. Production cycle time reduced by 40%. Overall cost per part decreased by 35% including material and process savings.
