HM-MX1 Coefficient of Friction Tester — Moving Sled Design for Standard Specimens

Product Introduction

The HM-MX1 is a precision coefficient of friction tester from HM Instruments designed for laboratory and quality-control environments where accurate measurement of static and kinetic friction coefficients is essential. Built around a moving sled architecture optimized for standard specimen dimensions, the instrument delivers repeatable test results across films, papers, textiles, coated surfaces, and metallic materials. A closed-loop motor with dual linear rail guidance ensures smooth, vibration-free travel at speeds from 1 to 500 mm/min, while industrial-grade force sensors resolve down to 0.001 N with relative error within ±0.5% and repeatability within 1%. The 7-inch capacitive touchscreen displays real-time friction curves and automatically calculates both static and kinetic coefficients in a single test sequence, eliminating the need for separate measurements. At $2,200, the HM-MX1 provides a cost-effective yet professional-grade solution for packaging manufacturers, material research laboratories, and quality assurance departments requiring compliance with GB/T10006-2021, ASTM D1894-24, and ISO 8295:1995.

Applications

• Packaging films — polyethylene, polypropylene, polyester, and laminated film friction characterization

• Paper and paperboard — printing paper, kraft paper, corrugated board slip property testing

• Textiles and woven materials — fabric smoothness and surface friction evaluation

• Coated and treated surfaces — varnish, lacquer, and functional coating friction assessment

• Metallic composite strips and conveyor belts — industrial material sliding behavior analysis

• Wood, rubber, and polymer materials — friction coefficient determination for product design validation

• Automotive components — brake pad, wiper blade, and tire tread friction testing

• Footwear and leather goods — shoe sole and upper material slip resistance measurement
