Blown Film Coextrusion Dies Intelligent design for optimized production We recognize that differing market demands and applications make it difficult for one die type to be effective across all sizes and extrusion applications.COEXTRUSION BLOWN FILM LINES From polymer to information Different variations in the design of coextrusion dies COLLIN multi-layer blown film lines are used for the development of products from multi-layer composites in laboratories, pilot plants or for small-scale productions. Collin units can easily be adapted to perform different tasks.Production steps: extrusion, printing, embossing, welding, recycling single extrusion head (die) which extrude the materials Extruders, head and operator.Three layer blown film extrusion (also known as blow film co-extrusion) is a process of Co-extrusion process will be the bottleneck operation for this project.Coextrusion of blown film Coextrusion is the extrusion of multiple layers of material simultaneously. This type of extrusion utilizes two or more extruders to melt and deliver a steady volumetric throughput of different viscous plastics to a single extrusion head (die) which extrude the materials in the desired form. The layer thicknesses.The third generation IBC controller from D.R.
