Clam shell barrel twin screw extruder family:

The barrels can be quickly opened. Both screws and barrels are designed as segmented.

The screw configuration, barrel setup, L/D, feeding and venting, screen changer, granulating way, and electric control mode can be optimally adjusted according to different material properties and processing requirements, in consideration of the machine versatility in other general applications.

Designed by CAD, the closely intermeshed screw elements have excellent self-wiping
characteristics, and can be interchanged with each other easily. With many years
experience in screw design and software development, we realize efficient solids
conveying, melting / plasticizing, mixing / compounding, dispersing, and pressure-buildup in twin screw extruders, in accordance with specific requirements of each process.

Meter feeders are equipped with single screw, twin screws (both intermeshing and
non-intermeshing), or springs to meet different flow bulk particulate properties.

Granulating system includes strand pelletizing, air-cooling strand pelletizing, air-cooling
die face cutting, water-ring die-face cutting, eccentric hot face cutting with special cooling, and underwater pelletizing units. Our engineers will recommend you best suitable way of granulating type according to your material characteristics and process requirements.

For most applications, standard nitrated steel is used for barrels and screw elements.
For applications with particular requirements, highly corrosion-resistant and highly wear-resistant construction materials with special heat treatment are also provided for customers to choose.

Owing to low vibration and low noise, the main extruder can be installed on most
solid grounds without special base.

Applications:
1) Plastic inorganic fillers: polymer blending (plastic alloy), plastic master batch
2) Engineering plastic reinforcement: glass fiber, flame-retardant pellet
3) Antibacterial, insulated and toughened materials for specific usage
4) Light / biology degradable film materials, amylum degradable plastics and
multifunctional anti-fog film materials
5) Thermoplastic elastomer: TPR, TPE, SBS
6) Improved pellets for PVC airproof pieces and thermo-soluble glue..
