Underwater pelletizing system is an equipment that produces uniform, spherical plastic pellets by extruding molten plastic through a die plate and into a water-filled chamber where it is immediately cooled and cut into pellets.
High efficiency, precise control over pellet size and shape, and is suitable for a wide range of polymers, especially Adhesives, petrochemical, masterbatches, reaction extrusion, elastomers like TPE, TPO, TPU and TPV.

1. General-purpose plastics: PP, PE, PS, etc., with good particle uniformity.
2. Elastomers/Soft materials: TPR/TPE/TPV/TPU, EVA hot melt adhesive (Shore A≤40), etc., with high viscosity and difficult cutting.
3. Engineering plastics: PA, PET, PBT, PPS, PEEK, etc., high-temperature and heat-sensitive materials, ensuring molecular structure stability.
4. Functional Masterbatches: Color masterbatches, filler masterbatches.
5. Specialty Materials: Biodegradable materials such as PLA, foaming materials, highly filled/recyclable materials.
6. High-Capacity Scenarios: Polyolefin polymerization/modification, single-line capacity up to 25 tons/hour, suitable for large-scale production demands ≥1000 kg/h.

Jwell started manufacturing screws and barrels in 1978, making it one of the earliest screw and barrel manufacturers in China. Its brand, "Jinhailuo", has become well recognized in the industry. In 1997, Jwell was established to begin the production of extrusion machinery. Today, Jwell is the vice president unit of the China Plastics Machinery Industry Association and one of the technology leaders in the extrusion machinery industry.
