Testing Instruments – Paper Industry

Testing Instruments – Paper Industry

IDM Instruments Pty Ltd. has a broad range of testing instruments to test materials within the paper industry. The testing instruments assist in Quality assurance and control processes. Thereby, helping firms to comply with industry-wide testing standards and offer high-quality paper products. The testing solutions can test paper materials based on various paper properties like thickness measurement, brightness, friction, tear testing, tensile testing, and many more. All these dimensions are tested to pass testing standards like ASTM, TAPPI, ISO among others.

Importance of Paper testing

Testing within the paper industry allows manufacturers to meet the necessary quality expectations like the strength of paper, water absorption qualities, bookbinding quality, etc. This process will allow for offering a compelling point of differentiation as compared to the competitors. Especially, where the quality of the paper is highly important. For example, companies offering 70 GSM paper have to fulfill the thickness requirements. So, thickness measurement equipment can be used to verify that the thickness is exactly the same.

Testing Instruments for the Paper Industry

Coefficient of Friction Testers

Model: C0055-M1 – Standard

Model: C0055-M2 – Variable Speed

Model: C0055-M3 – Variable Speed & Heated Platen

The standard C0055-M1 unit can measure Static COF (peak) from a resting position and continue to move testing surfaces in a relative motion to give an accurate kinetic COF (dynamic) result. The C0055-comes with the addition of variable speed from 50 – 300mm/min using a stepper motor for acuate variable speed control. With variable speed, touch screen operation & in-built heated platen, model C0055-M3 is most ideal for plastic film testing.

The software allows a choice of testing units, as well as complete statistics, and RS-232 for connection to an external computer.

Coefficient of Friction Tester – Incline Plane

Model: C0045

This instrument is used to determine the coefficient of static friction of most packaging materials by measuring the angle at which one test surface begins to slide against another inclined surface as the incline is increased at a constant and prescribed rate. As the plane rises at a rate of 1.5° ±0.5°/s, the first sign of movement from the sled is detected by a micro switch, stopping the plane movement and recording the relevant angle of the incline. The test is frequently referred to as a slide angle. The coefficient of friction is numerically equivalent to the tangent of that angle.
