Load testing is essential for ensuring the structural integrity and reliability of packaging containers such as bottles, jars, drums, trays, cartons, and boxes. It verifies that these containers can withstand the stresses of stacking, shipping, and storage without collapsing or deforming, thereby protecting the product inside. This testing helps meet industry standards, preventing product damage and loss, and ultimately saving costs associated with returns and replacements. Additionally, it aids in optimizing packaging design and material usage, ensuring a balance between strength and efficiency, while maintaining the brand’s reputation for quality and reliability.

This unit is under PLC control (with industrial-level stability) and operated through an HMI touch screen. The use of a precision ball lead screw mechanism ensures consistent and accurate speed and displacement control. It features a specially designed and unique program catering to tests of top load.

1.A 7-inch HMI  touch screen for user-friendly operation.

2.PLC control for efficient functioning.

3.Precision ball lead screw for reliable results.

4.Adjustable test speed.

5.Compatibility with multiple compression plates of shape and diameters.

6.Overload protection and automatic returning function.

7.Optional inclusion of a microprinter.

8.RS 232 port for data communication and professional software (optional ).

Peak: To measure the container crush/compressive load

Fixed Deformation: To measure the load when container is at a deformation

Fixed Load: To measure how sample deforms under a certain load

Single Compression: To compress the container once and then analyze

Cycle Compression: To compress the container in cycles and then analyze

Top load testing involves placing the container on the testing platform, aligning it properly , and applying a compressive force from the top. The force is increased gradually until the container deforms or collapses. Tester measure the applied force and deformation, recording the maximum force the container withstands or the deformation the container shows at a constant load. The data is analyzed to assess the container’s strength and performance against predefined standards.
