Nanjing, China — Nanjing Henglande Machinery Technology Co., Ltd. proudly introduces its 75mm high-torque co-rotating twin screw extruder integrated with a fully automated underwater pelletizing system, delivering superior pellet quality, stable high-output performance, and reliable continuous production for demanding compounding applications.
The 75mm twin screw extruder has become one of the most popular models in the global plastic compounding industry due to its balanced combination of output capacity, energy efficiency, and operational stability.
The 75mm model features:
High-torque gearbox design
Modular screw configuration system
Wear-resistant alloy steel screws and barrels
Precision temperature control via PLC system
Stable feeding and dispersion performance
With optimized screw design and high mixing efficiency, the machine ensures excellent dispersion for fillers, pigments, additives, and reinforcement materials.
Typical output capacity can reach 300–500 kg/h depending on material formulation.
The extrusion line is equipped with a high-performance underwater cutting system, which cuts molten polymer directly at the die face under water circulation.
Compared to traditional strand pelletizing systems, the underwater pelletizing system offers:
Perfect round and uniform pellets
Smooth pellet surface
Reduced dust generation
Stable cutting at high throughput
Better cooling efficiency
Continuous and automated operation
This makes it especially suitable for:
High CaCO₃ filler masterbatch
Black masterbatch
Engineering plastics (PA, PC, PET)
Biodegradable materials
High melt flow polymers
The system ensures consistent pellet size and improved downstream processing performance.
The 75mm twin screw extruder with underwater pelletizing system is widely applied in:
Masterbatch production lines
Engineering plastic modification
High-output filler compounding
Recycled PP/PE pelletizing
High-performance compound manufacturing
Its stable high-output capacity and precision pelletizing technology make it an ideal solution for medium-to-large scale production facilities.
As a professional twin screw extruder manufacturer in China, Nanjing Henglande Machinery Technology Co., Ltd. specializes in designing and manufacturing high-performance plastic compounding and pelletizing systems for global customers.
The company focuses on technological innovation, precision manufacturing, and customized extrusion solutions tailored to various industrial applications.
