Fibrous material extrusion die geometry: British American TobaccoRecent Research Landscape

The technical control lever is the specific configuration of the die assembly used to shape fibrous materials into rods or tubes. Precise control over die geometry and extrusion mechanics determines the density, airflow resistance, and structural integrity of aerosol-generating substrates.

What technical problems is British American Tobacco addressing in Fibrous material extrusion die geometry?

Inconsistent fibrous rod density

(2)evidences

Inconsistent material distribution during high-speed extrusion leads to structural defects in fibrous rods. Achieving uniform density ensures consistent filtration and mechanical integrity in the final product.

Nonuniform fibrous rod density

(2)evidences

Inconsistent density and alignment during the high-speed conveyance of fibrous strands lead to structural defects in aerosol rods. Ensuring uniform spatial distribution prevents airflow resistance variability and improves product consistency.
