It’s a big challenge to achieve color consistency for large production runs of plastic injection molded parts. To ensure consistency when molding colors, it’s essential that you have careful process control at every step.
It’s important to note that …
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…
The injection molding process begins with raw plastic resin, known as thermoplastic, being dumped into a hopper. This resin is then heated typically to between 300° – 650° Fahrenheit where it melts and is injected into a steel mold. These molds contain cavities that have been carefully manufactured to meet the specific designs of the […]
