The characteristics
1.The first stage is TSE twin screw extruder without die.Through the combination of barrel and screw, the extruder can exert its strong ability to make the thermo sensibility material like PVC melting, compounding,dispersing and decentralizing under the condition of no back pressure
2.The second stage is SJ single screw extruder.Because of the lower rotating speed, it can complete melting,compounding lengthways and forming stands steadily, avioding over heating.

The application
The date of the machine
1.Electric control system
Frame structure control cabinet
Imported electrical elements
Imported temperature control system
Imported driving system
Interlock and multi-protection
Adopting imported PLC (OMRON or SIMES ) to achieve optimized process control.Stronger function, steady performance and much higher accuracy.
It can be also accomplished full-set link-lock protection, trouble safeguard, fault alarm cluing and so on
Operation interface on touching screen is visual and marked, which is brief and easy to use.
2.The Gearbox
New-style project of parallel three-axises driving makes the convey axis, convey chain, decelerate and the torque assignment get together, which keeo it compact, and the key bearings are imported.
The select material of drive components is dainty.Including super intension alloy cementiteing steel, cementiting and quenching, gear grinding technics, strengthening of tooth face.So they can ensure high torque, high precision and low noise.
Soakage and coerce lubrication integrate smoothly.When the hydraulic circuit is over pressed, it alarms
3.The Screw Barrel
Euro-style rectangle barrel, reflux refrigeration is optimized and disposed, which makes temperature difference in C areas smaller
According to the material and special techinics demands, the material of cylinder can use high quality nitrided steel, corrosion proof or antifriction with corresponding process
The screw material is made of high tool steel 38CrMoALA or W6Mo5Cr4V2 by special heat- treament
The application of the machine
Elastomer TPU, TPE,TPO,POE,EVA,SBS
Thermo-plastic PE, PP, PS, PA modified
Low viscosity reaction polymer, all kinds of hot-melt adhesive
Pure polymer
Extensive heat and mass transfer, narrow residence time distribution, large surface to volume
ratio, continuous operatio. Ideal for high viscosity, high temperature reaction systems.Conti-
nuous polymerization or reactive extrusion like dynamic vulcanization, cross linking, grafting,
and chain extension of PP, TPU, TPE, TPV, PUR, PA, POM, PEI, PC, PMMA, PBT, PPS, etc.
