Calculating the appropriate tonnage is crucial to prevent issues like mold deflection, flash formation, and poor product quality.

To calculate the tonnage required for a blow molding machine, a formula known as the Bernoulli equation is commonly used. The Bernoulli equation takes into account the surface area of the mold, the maximum pressure required to mold the plastic, and other factors such as safety margins and the coefficient of friction between the mold and the plastic resin.

The formula for tonnage calculation is as follows:

Tonnage = (Pressure × Surface Area) / Safety Factor

In this equation, the pressure is the maximum pressure required to mold the plastic, measured in pounds per square inch (psi). The surface area is the projected area of the mold cavity, in square inches. The safety factor is a value that accounts for variations in material behavior, mold design, and other factors. It is typically set to a value between 2 and 5, depending on the specific requirements of the production process.
