This region demands high-capacity systems for primary resin production. Latin America’s growth is more localized, driven by packaging and construction sector demand, leading to increasing adoption of medium-capacity systems for compounding and recycling activities. Overall, while global demand remains strong, the strategic focus shifts regionally: high-volume capacity in APAC and MEA, and high-specification, sustainable technology deployment in Europe and North America.
Underwater pelletizing offers superior pellet shape uniformity (spherical), significantly reduces dust and fines generation, and provides immediate, controlled cooling, which is crucial for processing low-viscosity or sticky materials like TPEs and certain polyolefins, leading to higher product quality and bulk density.
Underwater pelletizers are optimally suited for a wide range of thermoplastic materials, including high-volume polyolefins (PE, PP), complex engineering plastics (PA, PET, PC), and thermoplastic elastomers (TPEs, TPUs). They are essential for materials that tend to clump or deform when cooled via traditional air or strand methods.
Industry 4.0 integration, leveraging IIoT sensors and AI, enables predictive maintenance, real-time optimization of cutter speed and water temperature, and remote diagnostics. This leads to reduced downtime, optimized energy use, and enhanced consistency in final pellet quality across continuous production cycles.
The lifespan of die plates and cutting knives varies significantly based on the processed material; abrasive compounds (e.g., highly filled plastics) cause faster wear. Maintenance involves regular inspection, precise knife pressure adjustments, and periodic replacement of carbide-tipped knives, usually every few weeks or months, depending on throughput and material hardness.
The plastic recycling sector is a major growth driver. Underwater systems are highly effective at processing varied and often contaminated recycled feedstock (PCR/PIR), converting it into uniform, high-quality pellets suitable for reintroduction into high-specification manufacturing, thereby directly supporting circular economy goals.
