Blown Film DIE
Flat Plate or "Pancake" Blown Film Die
Our patent pending "Pancake" Blown Film Die design integrates sets of three round plates that offer uniform gaps to minimize flow variations. Each Plate in the three-plate layer arrangement is aligned with precision via special tapered expanding pins. This pin design allows for repeatable precise alignment of all parts.
​
Process and blend multiple Blown Film Dies Materials with varying thermal properties for longer periods of time by isolating the temperature of different layers. Extrude various polymer materials into 3-10 Layer Blown Film with the capability to process materials with significant alternate melt temperatures or other properties in adjoining layers.
​
ADVANTAGES of Precision Flat Plate Blown-Film Die:
-
Outstanding Minimal Thickness Variation Without Additional Gauge Control
-
Blown Film Dies Amplified Production Rates from Reduced Down Time
-
Optimizing Temperature Control and Quicker Heating Abilities Through a Central Pin Integrating Internal Heaters
-
Low Leakage and Maintenance Issues
-
Capable of Processing Multiple Materials with Alternate Melt Temperatures or Other Properties
01
Split Flow Channels
The flow splitting channels, located between the top and middle plate, direct circulating polymer from the die entrance location to each spiral. Polymer flow follows round cross-section split flow passages to the spiral dispersion zone which avoids dead zones and hang-up locations creating precise channel lengths for each individual spiral.

02
Outstanding Minimal Thickness Variation Without Additional Gauge Control
The split flow design allows for the optimal thermal consistency and polymer dispersion and improves mixing in the spiral distribution zone; which is located between the second and third plates. Once the polymer flows across the spiral distribution zone toward the central pin; the polymer travels vertically upward to the next layer or die lip. Internal heaters in the central pin assist start-up and preserve process control.
