Industrial lubricant market is already saturated with numerous manufacturers. However, punching oil, unlike general-purpose industrial lubricants, is mainly used by large-scale manufacturers and requires strict testing and qualification before being adopted into mass production processes. In particular, major corporations often demand formal approval processes and documentation, making entry into this market quite difficult.

Due to these challenges, it is difficult for small and medium-sized lubricant producers to supply punching oil to mid-sized or larger companies. Product development can be costly and time-consuming, and the risks involved often lead companies to abandon projects midway.

Our company has developed a punching oil specifically designed for use in the aluminum fin press process, a key component in air conditioner manufacturing. This product has been successfully adopted by a major corporation’s production line.

This article is about quality requirements of punching oil for aluminum fin press.

Quality Requirements

1. Lubricity

The aluminum fin press oil must use high-performance synthetic ester as the base oil and include dispersing agents to ensure a uniform lubrication film, providing stable and consistent lubrication performance.

2. Friction & Wear Resistance

The product must meet optimal conditions for friction and wear resistance by carefully selecting and balancing additives based on their properties to ensure excellent workability.

3. Hydrophilicity

Low-volatility base oils and additives should be used to minimize oil residue after processing, facilitating easier post-processing cleaning.

4. Human Safety

Base oils must be certified by the FDA for indirect food contact, and all additives must be non-toxic and safe for human use, including those used in cosmetics and food-related applications. The formula must exclude toxic, carcinogenic, or otherwise harmful substances to prevent skin or respiratory health issues commonly associated with general-purpose oils.

5. Environmental Safety

The oil must be free of sulfur and chlorine compounds (below 1 ppm) and must not emit harmful substances when burned, ensuring a minimal environmental impact.

6. Cost Efficiency

To reduce manufacturing and logistics costs, additives should be localized as much as possible to reduce dependency on imports. The formula should also be flexible enough to support future new product development.

Each of these quality criteria must be validated through detailed testing to ensure compliance.

Comprehensive performance data—such as hydrophilicity, compatibility, processability, and volatility—should be recorded and maintained to allow prompt troubleshooting and technical collaboration for future performance upgrades and product development.
