Paper folding tester

Standards:

ISO 2758、ISO 2759

ASTM D774、 D774M

TAPPI T 403、TAPPI T 804

Test principle：

The machine uses the motor drive screw to move the fixture. The test fixture is placed between the upper and lower sets, and then press the test key. The upper pressure plate senses the load element on the upper pressure plate and converts the force into a signal to the computer monitor.

Application:

The bursting strength value obtained from this tester provides essential data for:

Quality control in paper and board manufacturing.

Evaluating the strength and protective capability of packaging materials.

Comparing different grades and types of paper and board.

Ensuring materials meet required specifications for their intended use.

Features:

Based on the provided description and typical Mullen testers:

Utilizes a motor drive system (likely for the hydraulic pump or clamping).

Clamping mechanism to hold the specimen securely.

Pressure application system involving a rubber diaphragm and hydraulic fluid.

Pressure transducer or load element to sense the pressure/force applied.

Conversion of the sensed force into a signal for processing.

Output of results to a computer monitor or digital display.

Measurement of pressure at the point of specimen rupture.

Likely includes control features for the rate of pressure increase.

May include features for data logging and reporting (implied by signal to computer).

Components made from materials like stainless steel (SUS#304) for durability and corrosion resistance.
