High quality blown film can only be produced using a high quality
die. Brampton Engineering innovative die designs and precise die manufacturing
techniques make us the world's leading solution provider for blown
film.
SCD® -3 Streamlined Coextrusion Die We invented this pancake modular die and coextruders around the
world recognize that our Streamlined Coextrusion Die
·
allows them to add value to their film by improving
the properties
·
provides independent control of skin (for example, gloss)
and core (for example, high tensile strength) layers
·
saves money by lowering resin costs - use thin layers
of expensive material for superior properties and less
expensive material for the remaining structure
·
gives them the versatility to run a wide variety of
materials to produce many different film structures -
the more layers the greater the flexibility
·
enables them to add more layers when needed
·
hearnesses the properties of different resins
·
peroduces superior film with the same resins in multiple
layers- the separation of materials gives superior barrier,
flex cracking resistance and thermoformability.
Distinguishing features
·
streamlined melt distribution
·
temperature isolation between layers
·
increased efficiency with fast flushing, changeovers
·
low maintenance
·
easy upgrades
·
convenient compact size
ISOtherm® SCD® provides super temperature isolation up to 150°C between adjacent
layers to enable coextrusion of
·
more temperature sensitive materials such as PVdC, rubberized
polymers, engineering plastics, EVOH, cross linkable polymers
and LCP making new and better structures.
An oil-circulating temperature control system maintains the module
at its pre-selected temperature by either removing or adding heat
as required due to any heat transfer between adjoining modules.
Cylindrical Dies bottom-fed
cylindrical spiral mandrel multilayer dies
·
available in lip size up to 100" (2.5m) diameter
·
oscillating or stationary models.
Distinguishing features
·
exclusive Taper-Lock die block technology (with concentric
tapers) eliminates the mechanical interference commonly
associated with spiral mandrels in multilayer configurations.
·
feed-block enables fast, easy changes in layer configuration
