For products that you want to be black and for products where you want to maintain dimensional accuracy!
"Black dyeing" is a treatment that causes the surface of iron to rust and prevents further rust progression. It is suitable for items that require dimensional accuracy due to its thin coating. It is recommended for products that want to be blackened or need to maintain dimensional precision. Additionally, to prevent contact between rotating and sliding metal parts, we also offer "manganese phosphate coating (Lubrite)," which does not allow phenomena such as seizure or galling to occur. 【Features (Black dyeing)】 ■ Thin coating (suitable for items requiring dimensional accuracy) ■ Low cost ■ Rust progression accelerates when "oil content" is depleted *For more details, please refer to the PDF document or feel free to contact us.
