Multi-layer Co Extrusion Casting Film Machine MMS-432-25-3

A laboratory triple-layer coextrusion calendering machine is a device utilized in laboratory settings for manufacturing multi-layer composite films. This equipment is commonly used in fields such as plastics and packaging materials.

It operates by extruding different types of plastic materials, merging them together to form a multi-layer structure, thereby creating thin films with specific properties.

Laboratory triple-layer coextrusion calendering machines play a pivotal role in the development of new materials, performance testing, and optimization of production processes. They enable researchers to produce multi-layer films under controlled conditions and evaluate their performance on a smaller scale. This contributes to expediting the development and experimentation of new materials, as well as simulating industrial production processes within a laboratory environment.

  • Multiple polymer melts are individually gathered through co-extrusion molds, forming a molten film flow composed of layers of different polymer melts. After cooling, this results in multi-layer co-extruded thin films or sheets.
  • An integrated PLC system controls the entire process, including extrusion, molten material metering, molten material pressure monitoring, calendering, rolling, and winding or cutting.
  • Imported molten material metering pumps, combined with pressure sensors, monitor molten material pressure to ensure consistent flow rates of the molten material.
