Jwell Multi-layer Co-extrusion Distributor
This coextrusion feedblock combines multiple polymer streams for uniform film, sheet, and board structures with 2 to 60 or more layers.
Key Selling Points
- Layer Flexibility:Configurations support 2 to 60 or more composite layers.
- Selectable Structure:Vane, plug, and leaf-style designs match different polymer requirements.
- Sequence Adjustment:Replaceable inlet sequencing changes the order of composite layers.
- Broad Application:Designed for layered film, sheet, and board with a flat die.
- Documented Materials:Examples include PS, HIPS, EVA, PE, PMMA, ABS, APET, PETG, PC, and UPVC.
Applications and Selection Notes
Use only with the documented polymers and extrusion functions described above. Final selection requires confirmation of resin, output, temperature, pressure, filtration or layer requirements, and line interfaces.
Product Description
A coextrusion feedblock combines separate polymer melt streams before they enter a flat extrusion die. This JWELL multilayer distributor is designed for film, sheet, and board production using various polymer materials, with the final configuration selected according to the required layer sequence and the behavior of the processed resins.
The documented product range includes vane, plug, and leaf-style arrangements. These structural choices give processors a practical way to match the feedblock to the material combination and production requirement. Layer order can be changed by replacing the sequencing shaft at the material inlets, allowing the composite structure to be reorganized without describing a different downstream die.
Depending on the selected configuration, the feedblock can manage from 2 to 60 layers or more. The supplied structure diagram shows representative two-, three-, four-, and five-stream feeding arrangements and example combinations involving PS, HIPS, EVA, PE, PMMA, ABS, APET, PETG, PC, UPVC, and recycled PS. These examples demonstrate configuration possibilities; final resin pairing and layer ratios require engineering confirmation for the buyer’s formulation and line conditions.
Used together with a flat die, the coextrusion feedblock provides a compact route to producing layered film, sheet, or board. Procurement should specify the polymers, number and order of layers, target product, extruder interfaces, throughput, and operating conditions so the appropriate feedblock structure and inlet sequence can be selected.
