Small Precision Three-Layer Co-Extrusion Blown Film Experimental Line

FBCL-20/03
The small precision three-layer co-extrusion blown film experimental line consists of three precision single-screw extruders, three-layer co-extrusion blown film die heads and blown film auxiliary machines. The equipment integrates the company's latest precision extrusion and high-performance blown film forming technology, with a wide process adjustment range and wide applicability. It can be widely used in the blown film performance test of polymer materials and the research of multi-layer blown film forming process. The modular design based on ergonomics is more convenient to operate and use, which can greatly improve the experimental efficiency and shorten the product development cycle. It is an ideal experimental equipment for scientific researchers.
*The extrusion screw is driven by a servo motor, with stepless and precise speed regulation, stable plasticization and good consistency
*Digitally designed co-extrusion die head, smooth flow channel without dead corners and material stagnation, and uniform material discharge
*The film frame is electrically lifted to facilitate film guiding and process adjustment
*The original vector air ring is adopted, which is energy-saving and low-noise
*Professionally designed small-diameter film bubble control system with stable width
*Traction servo motor speed closed-loop control, precise and stable longitudinal film guiding speed
*Based on PLC control system and touch screen operation interface, the equipment runs stably and the human-computer interaction is friendly
*Real-time measurement and graphic display of important experimental data, convenient observation
*The number of co-extrusion layers can be customized
Application range
*Preparation of three-layer blown tubular film
*Optimization of multi-layer blown film production process
*Performance test of polymer material blown film
*Research and development of new material formula
