Blow Up Ratio Calculator
To calculate the Blow Up Ratio (BUR), divide the final diameter of the film by the die diameter.
The Blow Up Ratio Calculator is a specialized tool designed for professionals in film extrusion and plastic manufacturing.
It helps determine the ratio of the inflated film diameter to the die diameter, a critical parameter for ensuring consistent quality and thickness in blown film production. By using this calculator, manufacturers can optimize the extrusion process, achieve uniformity, and improve overall product performance.
Formula
BR = Df / Dd
| Variable | Description | Unit |
|---|---|---|
| BR | Blow Up Ratio | Unitless |
| Df | Final Diameter of Film | Inches or mm |
| Dd | Die Diameter | Inches or mm |
Solved Calculations
Example 1: Calculate the blow-up ratio for a film with a final diameter of 24 inches and a die diameter of 8 inches.
| Step | Calculation | Result |
|---|---|---|
| Divide final diameter by die diameter | 24 / 8 | 3.0 |
Example 2: Determine the blow-up ratio for a film with a final diameter of 30 inches and a die diameter of 10 inches.
| Step | Calculation | Result |
|---|---|---|
| Divide final diameter by die diameter | 30 / 10 | 3.0 |
What is Blow Up Ratio Calculator?
