There are three ways to make custom colors for plastic injection molded parts.
For low volumes, only the first option makes economic sense, but in that case, achieving color consistency will be very difficult. Alternately, using compound custom material, or using a masterbatch colorant, allows color consistency within batches.
But these methods are only suited for larger production volumes of injection molding, as we describe below.
- Use pigments in the hopper (low-volume)
- Purchase custom compound material (high-volume)
- Use a masterbatch colorant (very high-volume)
