Recently, a desktop twin-screw extrusion granulation experimental line from HALU was successfully shipped to Shanghai, where equipment installation and operation training were completed.

Performance Characteristics:

• Features a compact desktop structure with a small footprint, suitable for university laboratories and corporate R&D centers;
• Equipped with a parallel, co-directional twin-screw system and modular screw element design, allowing for flexible adjustment of shear strength and mixing effect;
• Multi-zone independent temperature control with a temperature control accuracy of ±1℃, meeting the processing requirements of heat-sensitive materials such as PLA, PBAT, and TPU;
• Integrated vacuum exhaust device effectively removes moisture and volatiles, improving particle cleanliness;
• Equipped with strip drawing, water cooling, pelletizing, and winding units, achieving one-stop molding from melt to standard particles.

Application Areas:

• Covers all scenarios of material modification research in universities and research institutes;
• Facilitates rapid small-scale testing of new material formulations for enterprises, shortening the R&D cycle;
• Adaptable to the development and preparation of functional materials such as biodegradable materials and special engineering plastics;
• Enables transition from small-scale to pilot-scale processes, reducing the risk of industrial scale-up;
• Meets the standardized sample preparation needs of third-party testing institutions.

After equipment delivery, Hartek engineers completed mechanical installation, electrical commissioning, and basic operation training, covering start-up procedures, parameter settings, safety regulations, and key points of daily maintenance. The equipment is currently operating stably and has been put into routine experimental use.
