CF-200 Lab Laboratory Cast Film Line
A complete laboratory cast-film line for PE, PP, PC, PET and ABS — produce high-quality film in the lab, and measure its optical and physical properties while it is made.

What You Can Measure
With the optional inline testers, the line characterizes film as it is produced: fisheyes / gels and black specks (film defect tester), haze and light transmission (haze tester), and ethylene / propylene / VA / additive content (IR tester) — plus manual physical testing on the film you cast.
How It Works
A precision single-screw extruder feeds a coat-hanger die; the melt is cast onto twin water-tempered chill rolls, drawn and wound — all parameters (screw speed, zone temperatures, roll temperatures, winding tension) set and stored on the touchscreen control panel. The modular structure lets you add measurement instruments as your lab's needs grow.
Highlights
- Modular structure, easy to extend
- Touchscreen control panel stores all line parameters
