It is relatively easy to convert a percentage setting on your controller to the actual pressure applied to the plastic. The most important factor is that you need to know the maximum pressure capacity.
Question: How do I convert a pressure measurement which is provided in percentage? When the panel says 50%, what is that in pressure?
My Response: Percentage is per-cent or per-hundred. This is a ratio with 100 as the maximum and the percentage as a fraction of that. 50% = 50/100 = half of the maximum. To calculate this, convert the percentage to a fraction 50% = 50/100 = 0.50 and then multiply this by the maximum machine capability.
Pressure = (percent / 100) x Maximum
