How it works
The DX-F3S runs three extruders into one die head, so the inner, middle and outer layers can be dosed separately: keep the inner layer clean and sealable, put recycled resin in the middle, and control surface roughness on the outer layer for printing and lamination. It is the usual way to hold performance while reducing material cost.
Film is taken off through an upward rotating haul-off with a stabilising cage and combined internal and external cooling, which keeps the bubble steady and the gauge even. The line is controlled from a PLC and touchscreen with stored recipes, so the same order can be repeated with the same settings rather than re-tuned from scratch.
This model can be fitted with our in-house multi-layer co-extrusion die head, internal bubble cooling and upward haul-off (horizontal or vertical, depending on width and floor space) to improve gauge evenness and output.
Selection advice: send your resin grade, target film width or pouch type, daily output and existing equipment. We confirm screw, die head, station count and support equipment from that — so a machine that looked cheap does not turn out to be the wrong one.
What decides the result
These six points are what actually show up in uptime, yield and labour cost, so they are worth comparing between suppliers.
Even gauge
Spiral die head with internal cooling and stabilising cage keeps thickness variation under control, which reduces wrinkling in lamination.
Steady haul-off
Rotating haul-off limits film sway and closed-loop tension control gives straight, non-telescoping rolls.
Wide resin range
Runs LDPE, LLDPE, HDPE, mLLDPE, EVA, EAA and functional masterbatches.
Energy per kilo
High-efficiency screws, insulated barrels and variable-frequency drives lower power per tonne.
Serviceable by design
Recipes instead of mechanical re-setting between jobs, with access space kept around key components.
