Box Compression Tester ZY-KY800

Application：

The ZY-KY800 Corrugated Box Compression Tester is a multifunctional, standard-type quality testing device developed by our company. It is primarily used for compression strength testing of various medium-sized, standard corrugated boxes, as well as for testing the compression strength of entire packaging containers made from other materials with a compression strength of less than 50 kN (5,000 kgf), such as food and beverage packaging, instant noodle packaging, cosmetic boxes, beer packaging, grain and oil packaging, as well as small color boxes, medium-sized cartons, large cartons, honeycomb cartons, and other paper products. This instrument features high control precision and advanced development technology, making it currently the most cost-effective general-purpose corrugated box compression tester in China.

The compression tester features functions such as testing, displaying, storing, analyzing, and printing all parameters specified in the standard, as well as real-time display of compression curves. It includes data processing capabilities that allow for direct calculation of statistical results, along with automatic reset and fault diagnosis functions, making it easy to operate.

Test Features:

1. Stacking Strength Test Function—Used to determine the stacking strength of a specimen by applying additional pressure to simulate packaging conditions until a preset pressure is reached and maintained. Throughout the test, the testing machine repeatedly adjusts the pressure in this manner to ensure that pressure fluctuations do not exceed the specified range, until the specified stacking test duration is reached. When the total deformation of the specimen under pressure reaches 100 mm, the testing machine automatically terminates the test.
2. Fixed-Distance, Fixed-Force Test Function – Used to determine the ultimate compressive strength of high-end specimens with special requirements. The upper platen of the testing machine moves downward at a set speed, applies pressure to the specimen upon contact, and simultaneously measures the pressure value exerted on the specimen. Deformation measurement begins when the pressure reaches 220 N. When the specimen reaches the preset compression distance or pressure, the system automatically records the final pressure value and the specimen’s compressive deformation.
3. Compressive Strength Test Function – Used to determine the ultimate compressive strength of the specimen. The upper platen of the testing machine moves downward at a set speed. Upon contacting the specimen, it applies pressure while simultaneously measuring the applied force. Deformation measurement begins once the force reaches a preset value. After the specimen fails, the testing machine automatically records the peak force and the deformation under compression.
