High-Precision Ring Crush Tester (RCT) for Corrugating Medium

Ring Compression Tester Product Overview：

The ZY-YSY3000 Corrugated Base Paper Ring Crush Tester is an instrument designed for testing the mechanical properties of paper and packaging materials. By changing the test fixtures, it can perform six tests, including ring crush strength (RCT) for paper, edge crush strength (ECT) for cardboard, adhesive strength (PAT) for corrugated board, flat crush strength (FCT) for corrugated board, corrugated linerboard CMT, and corrugated linerboard CCT, among six other test items.

Principle of Operation：

A test specimen of a specific size is cut from the base paper in the cross-direction and formed into a ring, after which pressure is applied to it. The compressive strength of the test specimen is the ring crush strength of the base paper, which is calculated based on the specimen length and the

Core strengths：

This instrument is a multifunctional main unit; users can order the appropriate accessories separately based on their specific needs. It is designed for various strength tests on base paper and corrugated board, utilizing microcomputer touchscreen control technology. It features statistical processing of test data and supports print output.

1. The instrument employs microcomputer-based automatic measurement and control, ensuring high precision, stable performance, and reliability.

2. Compared to existing domestic models of the same type, this instrument features a shared main unit and control box; the drive system employs a combination of worm gear reduction and a synchronous motor. The overall design is simplified and intuitive.

3. The instrument features a 7-inch touchscreen display with a Chinese menu interface. During testing, it displays real-time test values—including peak force, current force, and other data—in real time.

4. It automatically positions the test specimen and locks test results, including peak force, displacement, maximum value, minimum value, and average value, for analysis by testing personnel.

5. Data memory: 99-set storage capacity, providing robust storage capabilities.

6. Multiple safety features: Data retention upon shutdown or power failure, data retrieval, printing, travel limit protection, overload protection, automatic reset, fault alarm alerts, and sensor non-linearity correction, effectively ensuring safe and convenient operation for users.

7. Three units freely switchable, conversion function: N (Newtons), kgf (kilogram-force), lbf (pounds-force).

8. Thermal printer: Uses a thermal printer cartridge imported from Japan, eliminating the need for a ribbon and the hassle of replacing ribbons or refilling ink, significantly reducing failure rates while achieving high-speed, low-noise printing.

9. Real-time clock: The time is displayed on test results during printing (powering the unit on and off does not affect the time; once set, it remains valid for long-term use).

10. Operation and display interface: Features a high-tech color LCD touchscreen module with two display modes—digital readout and graph—which can be switched at any time.

11. Exterior finish: Finished with a high-quality baked enamel coating, the unit is aesthetically pleasing and durable.

Q1: What is a Ring Crush Tester (RCT)?

A: A Ring Crush Tester (RCT) is a high-precision laboratory instrument used to measure the edgewise compression resistance of a paper or paperboard sample formed into a ring. It determines how much vertical pressure a thin strip of paper can withstand before buckling. This value is critical for assessing the mechanical strength of the raw materials used in the corrugated packaging industry.

Q2: Which international standards does the RCT equipment comply with?

A: Our RCT testing machines are strictly engineered to comply with global standards to ensure data consistency in international trade, including:

ISO 12192: Paper and board — Determination of compressive strength — Ring crush method.
TAPPI T822: Ring crush of paperboard (Rigid support method).
GB/T 2679.8: Chinese national standard for ring crush resistance of paper and board.

Q3: How do I prepare a sample for the Ring Crush Test?

A: Sample preparation is critical for accurate results. According to ISO 12192, you must use a precision Sample Cutter to cut a strip of exactly 152.4 mm x 12.7 mm. The strip is then placed into a specialized Ring Crush Holder (central disk) to form a uniform circle before being placed between the platens of the tester.
