Burnishing for precision small parts
Our service portfolio includes burnishing for precision small metal parts and related components. The goal is to improve performance and quality with an efficient and tightly controlled workflow. Treatments are carried out by specialist partner plants with vertical expertise and are applied only to parts manufactured in our workshop, ensuring end to end control.
Burnishing enhances not only oxidation resistance: it also offers excellent oil retention, reducing friction and improving the behaviour of moving components. We focus on uniform appearance, long-term durability and full compatibility with your technical specification.
Steel burnishing and turned parts
Burnishing is a chemical surface conversion applied to small metal parts most commonly steel to provide a low-glare black finish that is more resistant to oxidation.
After careful degreasing and cleaning, parts are immersed in a controlled bath; reagent composition and parameters are tuned to the base metal and target shade.
The process is widely used in automotive, home appliances/white goods and hydraulics, where a robust finish is essential without compromising machining precision.
Benefits for precision small metal parts
Each job starts from a detailed review of your requirements component type, material and end application to ensure the treatment delivers corrosion protection, finish uniformity and spec compliance.
After burnishing, parts receive a protective lubrication step that boosts durability and oil-film retention. On request, we can also provide assembly and delivery according to agreed logistics.
Our approach secures reliable results, predictable lead times and consistent quality, shipping components ready for demanding industrial applications.
