Friction Coefficient Tester

Friction Coefficient Tester Supplier Overview

Measure static and kinetic COF for films, laminates, paper, foil, rubber sheets, and coated substrates. Choose horizontal plane or inclined plane methods, with optional temperature and humidity control to mirror real conditions in packaging, automotive, electronics, and printing. As a manufacturer, we provide application-driven COF testing solutions, OEM customization, and global support for dependable quality control and development.

Testing Methods and Standards

Horizontal Plane (ASTM D1894 / ISO 8295 / GB/T 10006 / TAPPI T549)

Determine static and kinetic friction using controlled sled mass and traverse speed. Configurable speeds, sleds, and analysis deliver traceable, comparable results for inspection and R&D.

Inclined Plane for Paper and Coatings

Measure slip angle to assess surface treatments, coatings, and paper/board finishes. Stable mechanics and fine angle resolution reveal subtle changes in surface energy and printability.

Product Range

Horizontal COF Tester for Films and Flexible Packaging

High-stability drive, low-noise load cell, and precise speed control per ASTM D1894/ISO 8295. Interchangeable sleds (200–1000 g), 50–300 mm/min speeds, and auto reports streamline QC.

Inclined Plane COF Tester for Paper, Labels, and Print

Fine angle adjustment and quick clamping suit paper, board, labels, and coated substrates. Results correlate with handling, stackability, and print performance.

Temperature-Controlled COF Testing

Evaluate slip under set temperature and humidity using integrated or docking modules. Thermal stability limits drift for cold-chain films and heat-resistant laminates.

Compact/OEM COF Modules

Embed compact COF modules in lines or lab systems. Ethernet/Modbus and SDK support simplify data capture and MES/LIMS connectivity.

Key Features and Specs

Measurement Performance

COF resolution to 0.001 and accuracy up to ±0.01 help separate similar materials. Adaptive filtering improves static peak detection and kinetic stability.

Mechanics and Build

CNC-machined parts, rigid frames, and low-friction guides reduce vibration and backlash. Precision-ground sleds and fixtures keep contact area and pressure consistent.

Control and Data

Touchscreen or PC software provides method templates, batch runs, and auto reports (PDF/CSV). User roles, audit trails, and calibration reminders support data integrity.

Safety and Compliance

Emergency stop, overload protection, and interlocks protect users and samples. Documentation and calibration standards support audits and qualification.

Applications

• Plastic films and flexible packaging: verify sealability, machinability, and stackability; track additive dosage and aging.


• Paper, board, and labels: set COF ranges for feeding and print quality; support die-cutting and stacking.


• Rubber, polymer sheets, and interiors: assess tactile feel and squeak/rattle risk; pair COF with abrasion data.


• Foil, coated metals, and food-contact materials: stabilize unwinding, lamination, and packaging across temperatures and humidity.

How to Select a Coefficient of Friction Tester

• Sample type and thickness: choose sleds/fixtures that maintain contact without damage.


• Method, sled mass, and speed: confirm ASTM D1894/ISO 8295 or others; set 200–1000 g and 50–300 mm/min.


• Environment: add temperature/RH control if slip varies with conditions.


• Data and throughput: plan reports, permissions, LIMS/MES links, and batch or inline testing.

FAQs

Q: What is the difference between static and kinetic COF?

A: Static COF is the peak force to start motion. Kinetic COF is the steady force to maintain motion at a set speed.

Q: When should I use the inclined plane method?

A: Use it for paper/board and coated surfaces where slip angle relates well to handling, stacking, and print performance.

Q: How often should I calibrate a COF tester?

A: Follow your quality plan, typically annually, with interim checks using traceable references if usage is high.
