Smoothness Tester

Introduction:
Understanding and managing the coefficient of friction (COF) is vital in optimizing packaging processes across various industries. The COF-01 Coefficient of Friction Tester provides comprehensive solutions for precisely measuring COF, ensuring efficient performance and quality control throughout packaging operations.

Background:
The COF signifies the degree of friction between surfaces, influencing the ease of sliding between materials. In packaging, maintaining an optimal COF is crucial for smooth processing and minimizing issues during packaging creation, transportation, and storage. Various factors such as additives, treatments, and materials composition affect COF.

Application:
The COF-01 Coefficient of Friction Tester is versatile, catering to a wide range of materials including plastics, rubber, paper, and more. It adheres to industry standards such as ASTM D1894, ISO 8295, TAPPI T816, and GB 10006, ensuring accurate and reliable results.

Formula:
COF is calculated by dividing the force required for sliding by the perpendicular force between surfaces. The tester measures both static (�¼s) and kinetic (�¼d) COF, crucial for assessing stacking, cartoning, machinery processing, and other packaging scenarios.

Technical Features:
1. Advanced PLC control and HMI touch screen interface ensure user-friendly operation and stability.
2. Precision stepper motor and ball lead screw drive mechanism guarantee accurate testing.
3. Real-time test curve display and automatic result recording enhance efficiency.
4. Measures both static and kinetic COF for comprehensive analysis.
5. Compliance with multiple industry standards ensures reliability.
6. Integrated dot matrix microprinter for convenient data output.
7. Aluminum construction of the test plane ensures durability.
8. Optional professional software and RS232 output for enhanced functionality.
9. Customizable local language display for user convenience.

Heat Seal Tester is professionally applicable to the determination of heat-sealing temperature, dwelling time and the heat-sealing pressure which are references to the production of aseptic bag, food, pharmaceutical, daily chemicals, package and raw material.

Features
Micro-computer control tests. Touch interface is easier to operate.
Self-innovated "constant temperature control" system improves the accuracy of temperature.
The synchronous circuit of single bottom cylinder ensures the balance of pressure.
Aluminum-sealing jaws provide even and uniform temperature for different sealing surfaces
The upper and lower jaws controlling the temperature independently and the super-long thermal cover can meet different needs.
Dual switch modes of manual and foot make the safety and convenience.
Micro-printer embedded can get the results quickly.
The design of anti-scald and leakage protection is more secure to test.

Principle
HST-H3 Heat-Seal Tester is composed of upper and lower heat sealing jaws. Before the test, preset the values of heat-sealing temperature, pressure and dwelling time, then place the specimen in between the upper and lower jaws and press start button. The whole sealing process can be finished automatically.

Coefficient of Friction Tester is specialized in measuring the static and dynamic coefficients of friction of plastic film and sheet, rubber, paper, cardboard, woven bag, fabric style, metal material composite belt for communication cable and optical cable, conveyor belt. By measuring the smoothness of materials, the quality of materials can be controlled and adjusted. In addition, it can be used to determine the smoothness of cosmetics, eye drops and other daily chemical products.

Features
The dynamic and static coefficient of friction of the samples can be measured simultaneously in one test.
The speed can be adjusted to support different sliders.
The instrument can meet the requirements of GB, ISO and ASTM and the testing method can be selected according to the demands of customers.
The table and slide block are degaussed and processed by remanence , which effectively reduces the testing error.
The tester is equipped with touch interface and controlled by micro-computer, which is convenient for users to carry out operation and view data.
With professional software it can automatically process statistical analysis and reanalysis of original data of single and group results. In addition,superimposed comparison in group curves and multiple reports which can directly show the testing results to customers are obtained.
Micro-printer and standard USB interface facilitate the external connection and transmission between the instrument and data sharing system of laboratory.

Principle
The two experimental surfaces are placed flat together. Under a certain contact pressure, the two planes move relatively to each other and the required force is recorded. The weight of the slider divided by the test force is the friction coefficient.
