Fujifilm Prescale® is a unique, affordable and easy to use tool that reveals the distribution and magnitude of surface contact pressure in your battery lamination and calendering press.
When placed in your lamination or calendering press, the film instantaneously and permanently changes color in direct proportion to the actual pressure applied. Philosophically similar to the indication given by Litmus paper. Precise pressure magnitude is then easily determined by comparing the resultant color intensity to a standardized color correlation chart. No training or instrumentation is required.
Have you ever needed to evaluate pressure or force between two touching or mating surfaces? Previously, your only alternatives were strain gauges and load cells, that are both time consuming and difficult to interface. Now with the advent of our disposable one-time use pressure film, Fujifilm Prescale®, evaluating surface contact pressure distribution and magnitude is accurate, quick and highly economical.
Benefits
• Correct uneven lamination.• Minimize delamination during battery discharge.
• Minimize poor contact between the electrodes and their current collectors.
• Quickly observe and correct uneven thicknesses.
