This guide explains the main plastic extrusion types you will encounter in production planning, what each process is best for, and how to choose between single screw extrusion and twin screw extrusion when your target is recycling, compounding, or pelletizing.

​For plastic recycling plants and compounders, improving the efficiency of a single screw plastic pelletizing extrusion line means achieving higher and more stable output, reducing downtime, and keeping energy consumption under control while maintaining pellet quality.

​In plastic processing plants, color mixing efficiency directly affects output stability, color consistency, material loss, and overall production cost. Inefficient mixing leads to common problems such as uneven coloration, longer cycle times, excessive masterbatch consumption, frequent downstream adjustments, and repeated rework.
