For ECT, FCT, RCT, CMT, CCT and PAT Testing

In the packaging industry, the mechanical strength of corrugated board, paper, cartons, and shipping boxes plays a critical role in ensuring product protection throughout storage, transportation, and distribution processes. Packaging materials are continuously exposed to compression, stacking loads, impacts, and handling stresses, making accurate strength evaluation essential for manufacturers seeking consistent quality and performance.

The Multi-Function Crush Testing Machine is designed to perform a wide range of compression and crush resistance tests, including ECT, FCT, RCT, CMT, CCT, and PAT testing. In addition, the system can be used for box compression testing, box crush testing, compression strength evaluations, and permanent deformation analyses. Equipped with advanced software support, high-precision measurement technology, and flexible testing capabilities, the machine provides reliable data for both quality control and research and development activities.

Primary Purpose of the Device

The primary purpose of the Multi-Function Crush Testing Machine is to determine the compression strength, crush resistance, and structural performance of paper-based packaging materials.

By accurately measuring the mechanical properties of corrugated board and paper products, manufacturers can verify product quality, optimize material usage, improve production efficiency, and ensure compliance with customer requirements and international standards.

The device helps prevent packaging failures while eliminating unnecessary material costs caused by over-engineered packaging designs.

What Are ECT, FCT, RCT, CMT, CCT and PAT Tests?

ECT (Edge Crush Test)

The Edge Crush Test measures the edgewise compressive strength of corrugated board. It is one of the most important indicators used to estimate the stacking strength and load-bearing capacity of corrugated boxes.

FCT (Flat Crush Test)

The Flat Crush Test determines the resistance of corrugated board flutes against crushing forces applied perpendicular to the board surface. It evaluates the integrity and performance of the flute structure.

RCT (Ring Crush Test)

The Ring Crush Test measures the compression strength of paper when formed into a ring-shaped specimen. It is commonly used to evaluate the load-bearing characteristics of containerboard papers.

CMT (Concora Medium Test)

The Concora Medium Test evaluates the crush resistance of corrugating medium after laboratory fluting. It provides valuable information regarding the performance of medium paper in corrugated board production.

CCT (Concora Crush Test)

The Concora Crush Test determines the compression strength of laboratory-fluted corrugating medium. The test is widely used for assessing the quality and suitability of medium paper for corrugated packaging applications.

PAT (Pin Adhesion Test)

The Pin Adhesion Test measures the bonding strength between the linerboard and corrugating medium layers. It is essential for evaluating the adhesive quality and structural integrity of corrugated board.

Importance and Purpose of These Tests

Modern packaging systems must withstand a variety of mechanical stresses throughout their service life. Compression and crush resistance testing enables manufacturers to assess product performance before materials reach the market.

These tests help manufacturers:

  • Verify product quality and consistency.
  • Evaluate raw material suitability.
  • Improve packaging performance.
  • Reduce transportation-related product damage.
  • Minimize customer complaints.
  • Support quality assurance programs.
  • Meet international packaging requirements.
  • Generate reliable technical documentation for export markets.

Regular testing contributes significantly to maintaining stable production quality and achieving long-term customer satisfaction.

Scientific Principles of Testing

The testing process is based on the controlled application of compressive force to a specimen under predefined conditions.

During testing, the machine applies force at a programmed speed while continuously measuring load and displacement values. The integrated measurement system records critical performance parameters such as maximum load, crush resistance, deformation behavior, and failure point.

Advanced software analyzes these values in real time, providing highly accurate and repeatable test results. This scientific approach allows manufacturers to evaluate material behavior objectively and compare production batches with confidence.

Device Operation

Test specimens are positioned using the appropriate fixture or testing accessory according to the selected test method.

The operator defines testing parameters through the touchscreen interface or software system. Once the test begins, the machine applies a controlled compressive force while monitoring load and displacement data throughout the entire procedure.

The test can automatically stop based on predefined conditions such as force value, break point, or travel distance. Upon completion, results can be displayed, stored, analyzed, and reported through the software platform.

Technical Features

The machine is equipped with a modern touchscreen interface that enables simple and efficient operation. An emergency stop button enhances operator safety, while the dual-column construction provides excellent mechanical stability during testing.

With an accuracy of ±0.5%, the system delivers highly reliable and repeatable measurements. Its extensive speed adjustment range allows testing at extremely low or high speeds depending on the application requirements.

The displacement resolution of 0.001 mm enables precise deformation analysis and detailed material characterization. Programmable stopping functions allow the machine to terminate tests automatically based on force, distance, or specimen failure conditions.

Multiple measurement units, including Newton, kilogram, and MPa, provide flexibility for different industries and testing standards. The software supports Turkish, English, and French language options, making the system suitable for international laboratories and manufacturing facilities.

Its robust construction ensures long-term durability while minimizing maintenance requirements.
