Small Precision ABA Co‑extrusion Casting Line

Why You Need This ABA Co‑extrusion Casting Machine

 

why choose our products?

 

Troubled by high‑cost industrial trial‑run for new multi‑layer polymer films?
Wasting large‑volume raw materials when testing ABA film formulations?
Hard to transfer your lab‑developed recipe to large‑scale production?

 

POTOP FDCI‑25/22 Small Precision ABA Co‑extrusion Casting Line is your perfect solution.
This compact lab‑scale equipment fully replicates the complete industrial ABA cast‑film production workflow within your laboratory. It cuts your material consumption, lowers trial‑and‑error cost, and shortens your new‑material development cycle dramatically.All process data obtained from this lab machine can be scaled‑up directly to industrial production lines.

Small precision ABA co‑extrusion casting tester is a compact lab‑scale forming equipment developed by POTOP for the research and development of three‑layer polymer composite films.
It fully replicates the complete industrial ABA three‑layer co‑extrusion casting workflow. The full process, including melt extrusion, three‑layer polymer confluence, rapid chill‑roll casting, traction, edge trimming and constant‑tension winding, can be completed within a limited laboratory space.

This unit is equipped with two independent precision single‑screw extruders and an ABA three‑layer distribution co‑extrusion die, enabling accurate fabrication of A‑B‑A structured films. The outer layer A can adopt identical formulations, while the middle core layer B can incorporate functional additives for modification, barrier or toughening purposes.
Formulas and process parameters obtained from laboratory trials can be directly scaled‑up to industrial production lines, which greatly reduces trial‑and‑error costs and shortens the development cycle of new polymer materials. It serves as essential precision laboratory equipment for universities, research institutes and corporate R&D centers to prepare functional film samples and optimize manufacturing processes.
 

✅ Precise & Controllable ABA Three‑layer Structure
Independent feeding & proportion adjustment for dual extruders. Free combination of outer A‑layer and core B‑layer materials. Clear film inter‑layer boundary and stable thickness ratio, enabling fast trials of multiple layer‑ratio schemes.
✅ High‑precision Servo Closed‑loop Drive
All key units including extruders, casting rolls, traction rollers and winder are driven by independent servo motors. High synchronous accuracy, stepless speed adjustment and consistent melt output. Effectively minimize film defects such as thickness deviation, wrinkles and tensile deformation.
✅ Advanced Temperature Control Performance
Multi‑zone independent electric heating + air‑cooling system. Temperature control accuracy reaches ±1℃. Circulating‑water temperature‑stabilized chill roll, compatible with polymers with vastly different crystallization rates.
✅ Smart Touch‑screen Operation System
Siemens PLC plus 10‑inch color touch‑screen. Real‑time visualization monitoring for temperature, melt pressure, screw speed, line speed and winding tension. Saved recipe parameters can be recalled with one click; experimental data export facilitates comparison of multiple test groups.
