Box Compression Tester QualiBCT™ 20/50 Features

High Rigidity Structure Design:
By reinforcing the crosshead support and enhancing the compression platen structure, the machine is effectively protected against deformation even after long-term use.
Fixed Upper Compression Platen (Two Selectable Test Modes):
1. Fixed Parallel Platen.
2. Self-aligning U-joint Type Platen allows for angle adjustment based on variations in the sample's surface.
Lower Compression Platen:
Equipped with three force sensors to accurately measure changes in force during the application of pressure, these three sensing points ensure smooth transmission of force conditions for the sample during large-scale testing, providing improved protection for the sensors.
User-Friendly Operation:
The intuitive control panel simplifies the learning process. The tester includes a power switch, emergency stop, and elevation switch, making it easier and more convenient to adjust the compression plate position.

How to determine the safety factor for cardboard boxes?
Determining the safety factor for cardboard boxes involves using a specialized compression testing device specifically designed for packaging boxes. This equipment is commonly used to assess the protective capacity of corrugated cardboard boxes and packaging materials when subjected to external loads. The compressive strength of the packaging box is typically evaluated based on a safety factor, denoted as K. If the contents of the package provide support, it is recommended to have a minimum K value of 1.65. In situations where the contents cannot provide support, the K value should exceed 2. These specified values are instrumental in determining the necessary packaging strength.
There are two primary testing methods:
- Collapsed Compression Test: Apply pressure to the sample at a consistent rate until it collapses. The force will increase until reaching a peak and then decrease. The maximum force is recorded during this process.
- Constant Pressure Compression Test: Apply a sustained and fixed force to the sample for an extended duration. Measure whether the final compressed sample height exceeds that of the packaging item.
