Extrusion line with water cooling CFPL

laboratorycast-filmfor thermoplastics

Overview
The CFPL (Cast Film Pro Line) is a micro cast film line designed for precise process control for R&D and pilot production. It produces wide cast films or continuous strips from small compounder batches, reducing material waste and accelerating formulation development.

Key features

• Three calenders for extensive R&D capabilities and precise film handling
• Heated film die enabling rapid production of wide cast films
• Film thickness range from 5 µm up to strip thicknesses
• Adjustable cast speed 100–5000 mm/min with 1 mm/min micro-stepping
• Air knife positioned after the die and two air pins for stable film formation and reduced necking
• Second transport calender with master–slave speed control and pinch roll to reduce slippage
• Third collecting calender winder under torque control for automatic roll diameter compensation; tension adjustable in 1 Nmm increments
• Optional continuous feeding kit with mountable, water-cooled top hopper and dual continuous or forced feeding screws

Operational capabilities
The CFPL can produce wide cast films from a micro compounder batch in under 10 minutes and is capable of generating more than 20 distinct film samples per day, enabling fast testing and refinement of formulations including low-friction/slippery films.

Feeding & compatibility

• Continuous feeding kit supports automated continuous extrusion mode
• Designed for connection to Xplore micro compounders for continuous operation (examples: MC 15 HT, MC 5)
