TWO BE MONOLAYER BLOWN FILM DIE

-           bottom fed die with spiral mandrel distribution system

-           all melt distribution takes place in the spirals allowing the die lips to be sized to provide the optimum velocity and pressure balance characteristics necessary for uniform gauge film

-           flow passages designed using rheological flow simulation programs combined with years of practical experience to produce optimal polymer distribution

die components manufactured from 4340 machine steel. Body and mandrel are hardened to 26-32 Rc, die lips have additional hardening to 40 Rc. All parts are electroless nickel plated, plating is heat treated to a hardness of 60 Rc.

-           material flow surfaces highly polished to 8 Ra

-           taper-lock body and mandrels to ensure concentricity and make disassembly and assembly easy

-           die lips with recessed edges for protection from damage

-           adjustable outer die lip for concentricity with the inner die lip

-           insulated top surface of outer die lip to reduce heat loss

-           high capacity, long life, insulated ceramic heaters

One Custom Stationary Die Block And Double Header Die Carriage

-           custom flow designed  solid steel block to reduce possible hang-up points with a single inlet port and two outlet ports, one to each die assembly.

-           all required heaters

-           polymer flow passages are streamlined and polished to reduce degradation

-           a 24” straight adaptor customized to suit either new or existing extruders, includes ceramic band heaters wired to junction boxes

-           two custom 90 degree adapters each with  two standard melt access holes at 90 degrees to each other, one with a 1/4 inch (6 mm) deep melt temperature thermocouple and the other with a melt plug bolt

-                      die support cart manufactured from tubular steel, mounted on casters

TWO, BRAMPTON ENGINEERING DUAL LIP AIR RING

-           Uni-Flo "Dual Cool" air ring with dual orifice lips, precision machined to ensure uniform air flow onto the bubble

-           manufactured from heat treated aluminum

-           includes magnahelic air pressure gauge and air temperature gauge

-           design allows interchangeable lipsets

-           lips provided are for a 3 inch diameter die

TWO, BRAMPTON ENGINEERING AIR-LOCK IRIS

-           Model  ALI-04 iris with zinc coated blades in a steel housing

-           infinite manual adjustment

supported on oscillating portion of Model UF-04E air ring

-           includes access door for air ring lip adjustment

-           provides substantial cooling improvements, especially with low melt strength resins

Distributor Manifold

-           cyclone type distributor evenly divides the air from the blower into the number of air ring inlet ports, located underneath the die assembly

-           insulation on manifold eliminates condensation when using chilled air

TWO, BE BUBBLE STABILIZING CAGES

-           infinitely adjustable through layflat range

-           diameter adjustment is motorized, controlled from floor level   

four levels of guide arms with eight arms per level ensure excellent bubble stability

-           bubble contact through felt-covered rollers provides support without marking the film. A second set of felt covers is included as a spare
