Processing bio-composites like Polylactic Acid (PLA) or Polybutylene Succinate (PBS) blended with biomass fillers is notoriously difficult. These materials are incredibly fragile—prone to thermal degradation, moisture hydrolysis, and excessive shear. So, what exactly happens inside the barrel of your polymer compounding equipment during this process? Nanjing Haisi Extrusion breaks down the three critical stages of biodegradable compounding and how to navigate the narrow processing windows to produce top-tier pellets.

Every operator on the factory floor knows that the screw is the beating heart of your equipment. When this heart suffers from excessive wear and enlarged clearances, production output mysteriously drops, black spots multiply, and processing temperatures become impossible to control. The traditional solution is to pull the screw out for measurement. However, shutting down, cooling, cleaning, and extracting the screw takes anywhere from half a shift to a full day—costing you thousands in lost production. Is there a way to accurately diagnose screw wear without dismantling the machine? Nanjing Haisi Extrusion shares 4 advanced diagnostic methods to evaluate your polymer compounding equipment on the fly.

Whether you are changing colors, switching resins, or dealing with carbonized black spots, cleaning a twin-screw compounding extruder is a major challenge for factory floors. Extended changeover times, massive scrap rates, and the nightmare of manually pulling screws can severely drain your profitability. To help you protect your polymer compounding equipment and maximize machine uptime, Nanjing Haisi Extrusion has compiled 7 definitive workshop-floor strategies to master extruder cleaning and ensure your plastic pelletizing machine runs at peak performance.
