What are the steps in the production process of polyester masterbatches? The production process of polyester masterbatch can be roughly divided into 7 steps:

1. Weighing: Toners, carriers, lubricants, dispersants and other additives are weighed according to the amount of process requirements, the higher the accuracy the better.

2. Stirring: Put the weighed additives into high mixer in order according to the process flow.

3. Extruder: Set according to the carrier temperature of the color masterbatch, it can be started after holding for a certain period of time, and the speed can be increased from slow to fast.

4. Pulling bar: After the die is discharged, hold the bar in hand and move to the pelletizer at a constant speed, passing through the blow dryer or suction dryer in the middle.

5. Cut and pull: When the sliver reaches the inlet of the pelletizer, slowly increase the speed of the pelletizer.

6. Packaging: Packing according to customer needs.

7. Follow-up adjustment: Wait for the complete set of equipment to run normally for a period of time, and adjust the speed to the normal production speed in turn.

The above is the approximate production process of polyester masterbatches, but some manufacturers will refine some steps due to different requirements and rules, and should be operated according to requirements in actual operation.
