The Leather Edge Oil Fatigue Testing Machine is designed to evaluate the fatigue resistance of edge coatings applied on leather, synthetic leather, or recycled leather. Edge oil, typically composed of polyvinyl chloride, polyurethane, and other resins, is applied to leather edges for protection and aesthetic finishing. This instrument simulates repeated mechanical stress by kneading or rolling the coated leather edges under controlled loads, assessing durability and performance under real-world conditions.

Application

(1) Testing leather edge oil fatigue resistance in footwear manufacturing.

(2) Quality assessment of leather goods such as handbags, belts, and wallets.

(3) Evaluation of synthetic leather and PU-coated fabrics for edge coating durability.

(4) R&D of new edge oil formulations and coating materials.

(5) Inspection of recycled leather products for coating performance.

(6) Testing of colored or pigmented edge coatings to ensure color stability and adhesion.

(7) Industrial quality control for leather processing plants and finishing workshops.
