Extruders For All Blown Film Applications

Blown Film Extruders :
The challenge for blown film extruder is to deliver constant torque in a given dynamic situation. MES uses the latest

AC vector flux close loop technology along with rugged design Gearboxes to meet this challenge.
The customized screws with plain barrel, ceramic finned heaters and high efficiency blowers help in getting best possible quality melt at lowest possible temperature for better quality film at higher outputs.

Feed Screw :
MES specifically selects each screw to match a particular process to provide high extrudate quality at optimum throughput rates.

Lower melt temperature increases system throughput rate and provides less thermal degradation
Melt Channel Screws provide balanced feed and melting rates
The melt channels are sized to flush easily
It can deliver high throughput without increase in energy consumption for lower operating costs
Improved dispersive and distributive mixing permits a wide blending range

Control :
Barrel temperature zones are regulated by a microprocessor-based controllers for accurate temperature control
完整的πD programs and alarms
Available supervisory control packages include remotely programmable and fully integrated line control systems

Gear Boxes :
Rugged design gearboxes provide horsepower and torque ratings that surpass the usual standards
Hardened and precision-ground gears feature a helical design to ensure years of nonstop production
Integrally-mounted thrust bearing assures precise alignment to ensure that the bearing achieves a long working life

Drives :
AC vector flux closed loop drives provide optimum energy efficiency nd precise control

Spiral Mandrel Dies
Our Die Heads are characterized by selection of the right quality steels with in house computer aided machining with due attention given at each stage of die manufacturing, to ensure production of high quality films with tight gauge tolerances, right gloss and desired mechanical

Distinguishing Features :
Customised die design as per applications

The Taper Lock Body & Mandrel Assembly Design ensures excellent concentricity between the spiral mandrels and the die body
Streamlined Polymer Flow having No Stagnation and Dead Points
能力来处理关键层比率
Separate inner & outer lip temperature controls to avoid melt fractures

Stackable Co-extrusion Dies
The co-extrusion stack die offers most modular and versatile die design to allow processors to harness the characteristics of a wide range of resins to make structures with the required properties.

Distinguishing Features :
Temperature isolation between layers
Streamlined melt distribution
Easy upgrades due to modular design

The Eliminator Air Ring
The air ring technology for the cooling of polymers at its exit and its orientation area to achieve targets for gauge uniformity, output and physical properties of blown film.

Method of Operation :
The primary orifice does pre-cooling
The secondary orifice has dual functions
Creates a powerful Venturi effect that draws the partially cooled bubble radially outwards to the tip of the forming cone
This will thin the melt to improve the thermal conductivity as well as provide the main cooling effects by means of its high velocity
The Eliminator’s collar provides additional bubble support and increases the cooling efficiency, by simply adjusting the three rows of holes and collar height, the operator can fine tune and lock in the bubble shape

4+1 Pancake IBC System

4+1 Pancake IBC System Air Flow adjustments through Five Pancakes maximizes systems efficiency. This system has FIVE independently adjustable orifices :
The lower orifice pre-cools and stabilizes weak melt as soon as the polymer exits the Die
The adjustable air flow through each set of the other FOUR pancakes allows for a gradual increase in air velocity for maximum heat transfer
The air flow regulator plate acts as a by-pass valve allowing overall air
Exchange rate while maintaining optimum velocity through each pancake
A supervisory microprocessor based control system uses ultrasonic non contact sensors to sense the bubble position related to the bubble cage and adjust the flow of cooling air or / and the hot exhaust air in order to maintain the proper bubble size
Two separate blowers provide the air into and out of the bubble

Haul Offs - Vertical & Horizontal

MES offers two choices for Haul Offs - Vertical or Horizontal type for gauge randomization each having their own advantages.

Vertical Oscillating Haul Off:
Provides the provision to make film path vertical through
Set of turn bars & idler rollers mounted on platform for full
360º oscillation for uniform gauge distribution & excellent roll geometry.

特点:

Gauge randomization at fixed tension between primary nip and additional discharge nip helps to handle thin, stretchable and tacky film
Perfectly flattened films through full 360º oscillation
Excellent roll geometry

Horizontal Oscillating Haul Off:
Keeps the film path horizontal & achieves differential oscillation of set of turn bars to complete the gauge randomization process.

特点:

Gauge randomization by turning the film at 0º to 180º in both directions to achieve full 360º Oscillation
Economical system as compared to Vertical Oscillating Haul-Off
Compact system

Surface Winders :

Distinguishing Features :
Fully automatic roll change over
Variable surface pressure between the wound roll and the drum allows roll hardness to be precisely controlled
Full width, knife guard, incorporating safety interlocks with the cut off knife
Digital Length counter for warning
Cut over sequence monitored through a PLC
Full emergency stop system
Longer Guide Beds to unload wound roll

Optional Features :
Static Eliminator bar
Taper Tension controls
Full- roll unloading allows roll to be lowered to floor level hydraulically
Trim re-winder unit
Hoist for empty air shaft loading
