Cardboard Strength Testing Machine

The cardboard strength testing machine measures the compressive strength of cardboard by applying mechanical pressure, which is used to evaluate the load-bearing capacity of packaging. The principle involves placing a sample between compression plates and applying pressure at a constant rate until deformation occurs, recording the maximum pressure value. It is used in carton factories and quality inspection agencies to verify the reliability of transport packaging.
Selection
When selecting, consider whether the test range matches the product strength, whether the platen size covers the specimen specifications, and whether the accuracy meets standard requirements. Pay attention to the speed adjustment range and data output methods, and verify the equipment calibration certificate. Ensure the spatial layout fits the installation conditions and that maintenance costs align with the budget.
