Solution
This type main application to twin screw compounding filed , which can be used for polymer coloring, filling and blending, and also other mechanics, electrical, thermoplastics, optical, processability, and anti-environment and anti-biological function modification.
| Model | L/D | Screw Speed (rpm) | Capacity Range ( kg/hr) |
| CJWH65 | 36~48 | 400~900 | 300~800 |
| CJWH75 | 36~48 | 400~900 | 500~1000 |
| CJWH95 | 36~48 | 400~900 | 800~1500 |
1.Instead of traditional casting heater (outside the barrel), we use cartridges heater inside the barrel, and it will save energy. The polymer will melt mostly by heating, not kneading elements, so the life of screw and barrel are longer, and the quality of the compounding is better.
2.With special cooling way barrel, more uniform and faster cooling.
An engineering plastic compounding line is a high-performance twin-screw extrusion system designed for polymer modification. Jwell’s CJWH series lines are used for polymer coloring, filling, blending, and functional modification including mechanical, electrical, thermal, optical, processability, and environmental/biological resistance enhancement, meeting the strict requirements of high-end industrial applications.
Jwell’s lines are compatible with all mainstream engineering plastics and high-performance polymers: PA6/PA66, PC, ABS, POM, PBT, PET, as well as special materials like UHMWPE, PEEK, PPS and PI. We have mature solutions for high-temperature, high-viscosity and high-fill compounding processes.
Jwell offers three standard CJWH series models: CJWH65 (300-800kg/hr capacity, 400-900rpm screw speed), CJWH75 (500-1000kg/hr), and CJWH95 (800-1500kg/hr). All models feature an adjustable L/D ratio of 36-48, providing flexible process adaptability for different modification requirements.
Jwell adopts innovative internal cartridge heaters instead of traditional external casting heaters, reducing energy consumption significantly. This design allows polymers to melt mainly through conduction rather than shear kneading, extending screw and barrel service life by 30% and improving compounding uniformity. The special barrel cooling system ensures faster and more uniform temperature control.
Modified engineering plastics produced by our lines are widely used in automotive parts, electronic and electrical components, aerospace, medical devices, industrial machinery, construction materials and consumer goods. They provide enhanced strength, heat resistance, flame retardancy and electrical insulation properties.
Yes. Jwell provides fully customized solutions based on your target materials and modification processes. We can adjust screw configuration, feeding system, degassing unit, pelletizing system and automation level, with proven experience in PEEK compounding, UHMWPE compounding and high-fill glass fiber reinforced systems.
Compared with traditional compounding equipment, Jwell’s internal heating design saves 15-25% energy consumption. The precise temperature control system and optimized screw profile ensure excellent dispersion of fillers and additives, resulting in consistent material properties and minimal performance variation between batches.
The standard lead time is 50-65 working days after order confirmation. We have successfully delivered engineering plastic compounding projects to over 120 countries and regions worldwide. We provide full export services including professional packaging, freight arrangement, customs clearance support, and on-site installation & commissioning by certified engineers.
