"Blackening is a common surface treatment method for mechanical equipment, which involves creating an oxide film on the surface of the workpiece to isolate it from the air and prevent rusting.
Traditional blackening, boiling blackening, and black zinc plating processes often result in weak adhesion, susceptibility to rust, and fail to meet environmental standards. Rust on the products not only affects their dimensions but also significantly impacts their appearance, diminishing their competitiveness in the industry and tarnishing the brand's overall image. As per numerous customer complaints, some products start rusting before they even reach the customers' hands, leading to reduced customer satisfaction.
To address these issues, our company has introduced a special blackening process that penetrates steel components, effectively resolving the problem of conventional blackening's susceptibility to rust. This has substantially improved the rust resistance of the products, surpassing the capabilities of traditional blackening, boiling blackening, and black zinc plating processes.
The rust resistance can be further enhanced based on customer requirements, with the highest salt spray resistance reaching up to 200 hours. Moreover, this blackened product complies with national environmental standards.
Products treated with this blackening process have a non-reflective, wear-resistant finish, making them suitable for optical sensing needs on automated equipment."
