Application Background

The cow leg separator is a ground-mounted component used in modern milking parlors to gently guide dairy cows into a stable stance, automatically separating their hind legs to facilitate milking.

This device often features mounting holes for spray nozzles, allowing for automated cleaning or sanitizing of the udder and legs using water or disinfectant spray.

Previously, the separator was typically made from short glass fiber reinforced plastic.

However, under repeated load, hoof impact, and exposure to harsh farm environments—such as manure, moisture, and cleaning chemicals—short fiber materials often suffered from insufficient strength, deformation, cracking, or premature aging.

Advantages of PA6 Long Glass Fiber 30% (LGF-PA6)

• High Load-Bearing Strength
PA6 reinforced with 30% long glass fiber (LGF-PA6) forms an internal continuous-fiber skeleton during molding, significantly boosting mechanical strength. This allows the separator to safely withstand the full bodyweight of cows stepping or standing on it without deformation or breakage, ensuring safety and long-term structural stability.

• Excellent Chemical Resistance
Farm environments expose equipment to a mix of urine, feces, disinfectants, and detergents. LGF-PA6 exhibits strong resistance to chemical corrosion and environmental degradation, maintaining its integrity and mechanical properties over time—critical for hygienic and durable milking operations.

• Superior Impact and Fatigue Performance
Unlike short fiber composites, LGF-PA6 offers enhanced fatigue durability, effectively handling daily stress from cow movement, hoof impact, and vibrations without cracking or weakening, reducing maintenance and replacement costs.

• Dimensional Stability and Clean Finish
With reduced shrinkage and warping during injection molding, LGF-PA6 ensures tight dimensional tolerances for secure fitting of spray system components. The smooth molded surface enhances appearance, reduces dirt buildup, and simplifies cleaning, supporting farm hygiene standards.
