Air Ring


  Air ring:
 The unique flow design of our air ring eliminates film
 chatter while uniformly providing the air volume needed
 for high production speeds, optical properties and
 thickness control  are also improved. Built based on a
 latest new design, the air ring  stands out for its
 exceptional efficiency on double lip production for
 LLDPE and LDPE as well as single lip for HDPE.
 Fabricated in a special  aluminum alloy, it is machined
 with great care to avoid turbulence. Hoses with tangential
 inlets leading from the air box to the ring provide an even,
 turbulence free flow of air. The blower-system is
 dimensioned in accordance with volume and pressure
 requirements to supply the system with its cooling needs.
Screw
  Screw:
 Our screw can be designed either for high 
 output plastification of specific polymers or for 
 general purpose and versatile application. 
 Screws with diameter 25 to 150mm have 
 proven flexibility and versatility of our basic 
 concept.
Die
  Die:
 We supply mono- & co-extrusion dies for single & up
 to three layer film structures, with die sizes from 10 to
 1200mm, stationary and rotating. Our dies are based
 on the spiral mandrel system, the layout criteria are low
 pressure drop, low melt temperature, equal flow
 distribution, good purging & also, quick color change.
 Structure is combined with ultra precision producing,
 high quality steel, surface treatment and coating.

Oscillating Nip Roller Device
 Oscillating nip roll device :
 Oscillating nip roll system mainly conquers the
 troublesome rotary die maintenance problems
 which happens for several decades, in addition,
 also provides the most efficient way to randomize
 gauge variations which caused by ambient drafts,
 it results in smooth and perfect production roll to
 the most.
Co-Extrusion

 Co-extrusion die:
 1.The material composition can be two-layer of
    A+B structure,three-layer of A+B+C or A+B+A.
 2.Die is made of high quality alloyed steel with
    nitrided & quenchig treatment to make sure non-
    transformed of material under high temperature.
 3.Flow channels are hard chrome plated & highly
    polished treatment can provide flow channels
    smoothly & material non-obstruted.
 4.The design of die improves uniform of film
    thickness & produces superior products.
