Salt Spray Testing Equipment

Advanced Salt Spray Testing: We utilize our dedicated salt spray chambers to perform accelerated corrosion resistance tests. By simulating harsh environments, we can assess the durability and anti-rust properties of our products in just 24 hours, achieving results that would otherwise take up to a year in natural conditions. This ensures the long-term protection of your equipment.

Anti-Rust Oil Durability Testing (Short, Medium, & Long-Term)

We conduct stringent salt spray testing to validate the performance of our rust preventive oils, including MORESCO SP-300 and WILL W-609, under carefully controlled conditions of 35 °C chamber temperature and 47 °C saturated air tank temperature, with a spray collection rate of 1.6 mL per hour over 8 hours. This rigorous testing ensures that metal components receive reliable short-, medium-, and long-term protection, giving customers confidence in the durability, corrosion resistance, and overall effectiveness of our products. By simulating real-world environmental conditions, HLJH guarantees consistent product quality, optimizes formulations for maximum performance, and delivers solutions tailored to the demands of industrial applications, reinforcing our commitment to excellence in metalworking lubrication.

Quality Assurance Laboratory

At HLJH, our Quality Assurance Laboratory is dedicated to comprehensive comparative testing of cutting oils and industrial lubricants. We specialize in evaluating critical performance metrics such as anti-rust properties, material compatibility, and tool life, providing clients with reliable, data-backed insights. Through precise data analysis, we generate detailed comparison reports that empower customers to make informed decisions and select the products best suited for their specific machinery and applications. Our laboratory also enables customized OEM/ODM solutions, ensuring each client receives a tailored lubrication system designed to maximize efficiency, performance, and reliability.

Aluminum Compatibility & Corrosion Testing

At HLJH, we perform this aluminum compatibility and corrosion/oxidation test to ensure the safety and non-reactivity of our lubricants with sensitive metals. Aluminum test pieces are first ground and thoroughly cleaned before being partially immersed in a 5% diluted sample of the lubricant. The submerged pieces are then conditioned in a constant-temperature chamber at 30 °C for 48 hours. After immersion, the pieces are carefully inspected for signs of corrosion or oxidation, confirming their compatibility and the protective performance of our products. This procedure represents HLJH’s standardized testing method for evaluating the quality and reliability of our oils.
