Among his topics are die design: basic considerations, project planning, the design of a simple die, simulating melt flow, spiral die, monolayer dies for a range of sizes, coextrusion
pipe dies, coextrusion
three-layer die, three-layer-plus-striping die, and materials for extrusion dies.
Tenders are invited for purchase of a film of high-barrier coextrusion
lower and upper layer with interlayer flexoprinting 3 colors
ST Blow Moulding says the new machine is suitable for the production of parts with materials in monolayer, coextrusion
or SeCo (Sequential Coextrusion
), should DuPont need to produce items requiring different mechanical or chemical properties in predefined areas.
is a coextrusion
crosshead for tray-cable applications.
In recent years, advances in coextrusion
technology have led to the development of micro- to nano- layered polymeric structures via layer multiplication extrusion [1-3].
The accompanying figures below show the interface shape (shown in blue color), velocity, and pressure distributions in a complex profile die predicted by the polyXtrue coextrusion
die design module.
TPE monoprofile and coextrusion
lines are also described, along with a rubber-TPE hybrid extrusion system.
The outer-layer forms a material in a coextrusion
method and forms at least one of the outer layers from the outer-layer forming material.

Contract notice for Supply and installation of complete lines with coextrusion
systems from Macro Engineering & Technology, Mississauga, Ont.
Another recent development is the AB coextrusion
die which gives a 4:1 blow-up/stretch ratio and D-S says requires fewer blowing agents to achieve a high-density product.
