Short Span Compression Tester Cardboard Compressive Strength Testing Machine For Paper Container Board

The SCT-01 Short Span Compression Tester is a highly advanced instrument designed for determining the compressive strength of paper and board materials. This specialized testing machine is ideal for assessing the strength of materials used in the manufacture of containers and boxes. The SCT-01 is particularly effective for testing papers and boards with a grammage ranging from 100 g/m² to 400 g/m². With its precise measuring capabilities, this Short Span Compression Tester is an essential tool for industries requiring rigorous material quality assurance.

Application of the SCT-01 Short Span Compression Tester

The SCT-01 Short Span Compression Tester is specifically engineered to measure the compressive strength in both the machine and cross-directions of various paper and board materials. It provides valuable insights into the performance characteristics of these materials, ensuring they meet the necessary standards for packaging, food, medical, and beverage industries. By utilizing the SCT-01, manufacturers can optimize their material choices and enhance product reliability.

System Description of the SCT-01 Short Span Compression Tester

Equipped with two robust clamps, each 15 mm wide, the SCT-01 ensures accurate and consistent testing. The clamps feature a stationary jaw and a movable jaw, each measuring 30 mm in length, designed with high-friction surfaces to securely grip the test specimen. The constant clamping force of 2300 ± 500 N guarantees that the test piece remains firmly held throughout the test, providing reliable results.

Upon initiating the test, the free span between the clamps is set to 0.70 mm ± 0.05 mm. The clamps move toward each other at a speed of 3 mm/min ± 1 mm/min until compressive failure occurs. The SCT-01 includes an advanced force measuring unit, PLC control, and an HMI touch screen display, allowing users to determine the maximum compressive force with precision.

Technical Features

• PLC Controlled and HMI Operation: The intuitive touch screen interface simplifies operation and enhances user experience.
• Pneumatic Sample Clamping: Adjustable clamping force ensures the secure holding of various sample sizes.
• Adjustable Test Speed: Customize the speed according to your specific testing requirements.
• Safety Features: Equipped with an emergency stop button and over-range protection for enhanced safety during operation.
• Multi-Unit Display: Displays force measurements in N (Newtons), kgf (Kilogram-force), and lbf (Pound-force).
• RS 232 COM Port: Optional computer software for data analysis and reporting.

Test Principle

In the SCT-01 Short Span Compression Tester, a test piece measuring 15 mm wide is clamped between the two jaws. The jaws are set 0.70 mm apart and are forced together until compressive failure is observed. The instrument accurately measures the maximum force applied, allowing users to calculate the compressive strength effectively.

Test Procedures

1. Clamp the test piece securely in the jaws of the SCT-01.
2. Initiate the motion of the jaws and monitor the maximum compressive force displayed.
3. Conduct tests on a minimum of 20 specimens in both machine direction and cross-direction for comprehensive results.
4. For repeated tests on a single specimen, ensure that the test area does not overlap with previous clamping zones.
