thickness adjustment systems

Restrictor-bar models for sheet production,which provide uniform melt distribution over a wide range of material viscosities and throughput rates.Restrictor bars can be at 30, 45,90 degrees.

 

Lip adjustment systems:

1.automatic control system:

This system is the premier technology for precisely controlling the thickness profile of film,thin sheet and coatings .in addition to making prossible higher-quality,more accurate products, the automatical control system can generate substantial raw material savings compared to conventional manual adjustment

2.Fast Gap system (fast open lip adjustment system)

   The system permits processors to vary the lip gap within a range of 6.0mm without taking a die off line.
A single-point adjustment mechanism allows operators to quickly change thickness settings for new runs, and return to previous settings after purging or die lip cleaning, saving valuable production time and reducing scrap.
This fastgap system is used in sheet dies (lip opening range within 7mm).

Standard design for adjusting die lip
For Upper lip

  • push only fine adjustment on flexible lip (for:film die & sheet die)
  • push & pull adjustment on lip(for:film die & sheet die)
  • mechanical push adjustment (for:sheet die)
  • Multimode lip replacement (for:sheet die & proximity coating die &multi-manifold die)

For lower lip :

  • Stationary type (for:film die & sheet die )
  • Rough adjustment (for :sheet die)
  • mechanical push adjustment (for:sheet die)
  • Multimode lip replacement (for:sheet die & proximity coating die &multi-manifold die)
  • push only fine adjustment on flexible lip( for:coextrusion multi-manifold die)
  • push & pull adjustment on lip ( for:coextrusion multi-manifold die)
