Ball Pressure Method And When It Applies

The Ball Pressure method checks the heat resistance of parts in electrical equipment by assessing indentation under defined load and temperature. Product standards often call for checks at around one hundred twenty five degrees Celsius although the exact value depends on the application. We can help with material choice design and documentation for your parts.

Heat Resistance Under Load In Service

See how the ball pressure method verifies deformation at temperature and design parts and materials to meet typical checks around one hundred twenty five degrees Celsius.

    What Ball Pressure Checks

    Heat Resistance Under Load

    The method places a steel ball on the material at a set temperature and load and then measures the indentation. The result indicates whether the part can resist deformation under heat in service. The required temperature and acceptance criteria come from the relevant product standard. Share your target and we will advise suitable materials and thicknesses.

    Design Choices That Help Parts Pass

    Thickness Support And Local Stiffness

    Heat softening is influenced by thickness local ribs and support around fixings. Increasing stiffness and avoiding stress raisers near hot spots can improve outcomes. We can review drawings and suggest local design tweaks that help meet the specified requirement while keeping weight and cost efficient.

    Match Grade To The Required Temperature

    HPL plates and engineering plastics such as PC and certain FR ABS or PC ABS grades are common in panels. Performance depends on grade and thickness. We cut to size machine and finish to drawing and ship with a Certificate of Conformity. Supplier data can be provided where available for the selected material.
