Advanced Solutions for Durable & Aesthetic Black Finishes
The Raymond Roller Plating Blackening Equipment Production Line offers an advanced and efficient solution for applying a durable, aesthetically pleasing, and protective black finish to a wide range of small to medium-sized metal components. This specialized production line is designed for the mass treatment of parts through a controlled chemical process, resulting in a uniform black oxide or black chrome coating. Blackening is a conversion coating process that chemically reacts with the metal surface to form a thin, integral layer of black iron oxide (for ferrous metals) or a black chromium compound (for black chrome plating), providing enhanced corrosion resistance, reduced light reflectivity, and improved aesthetic appeal.
Our blackening equipment lines are engineered for high throughput and consistent quality, integrating automated barrel or rack plating systems, precise temperature and chemical concentration control, and efficient rinsing and post-treatment stages. Ideal for fasteners, automotive parts, tools, and decorative items, the Raymond Blackening Production Line ensures a deep, uniform black finish that is tightly adherent to the base metal. We leverage insights from leading European, American, Japanese, and Korean manufacturers to deliver systems that are not only robust and reliable but also environmentally conscious, with integrated wastewater treatment and fume extraction. Partner with Raymond for a state-of-the-art blackening solution that enhances product performance, extends lifespan, and meets stringent industry standards.
The Raymond Roller Plating Blackening Equipment Production Line typically involves a series of meticulously controlled steps to achieve the desired black finish and protective properties. The exact sequence may vary slightly depending on the specific blackening process (e.g., black oxide, black chrome) and the substrate material.
Parts are thoroughly cleaned to remove oils, grease, rust, scale, and other contaminants. This usually involves alkaline cleaning, rinsing, and acid pickling or descaling. A perfectly clean and active surface is paramount for uniform blackening.
Multiple rinsing stages ensure that all cleaning and pickling residues are completely removed before the blackening step.
Cleaned parts are immersed in the blackening solution. For black oxide, this is typically a hot alkaline solution that reacts with the iron in the steel to form a black iron oxide (magnetite) layer. For black chrome, an electrolytic process is used to deposit a black chromium layer. The parts are tumbled in barrels for small components or racked for larger items to ensure even exposure.
Parts are thoroughly rinsed to remove any residual blackening chemicals.
This is a critical step for enhancing corrosion resistance. Blackened parts are immersed in a rust-preventative oil, wax, or lacquer. The porous nature of the black oxide layer absorbs the oil, providing significant corrosion protection. For black chrome, a clear lacquer or sealant might be applied.
Finally, parts are dried and subjected to rigorous quality control inspections for appearance, uniformity, adhesion, and corrosion resistance.
Raymond Roller Plating Blackening Equipment Production Lines are built to deliver high performance, reliability, and adaptability, incorporating advanced features inspired by global industry leaders.

The Raymond Roller Plating Blackening Equipment Production Line is engineered to directly address common challenges faced by manufacturers requiring efficient and high-quality blackening solutions, transforming operational hurdles into competitive advantages.
Our Solution: Our automated lines ensure precise control over process parameters, leading to a consistently deep, uniform black finish across all parts. This eliminates patchiness and provides a superior aesthetic, crucial for both functional and decorative applications.
Our Solution: The blackening process, especially when combined with our recommended post-treatment oils or sealants, significantly enhances the corrosion resistance of metal components. This extends product lifespan and reduces warranty claims, even in moderately corrosive environments.
Our Solution: Our roller (barrel) plating systems are specifically designed for efficient mass processing of small parts. This automation drastically reduces labor requirements and increases throughput, leading to significant cost savings per unit.
Our Solution: Black oxide is a conversion coating that results in negligible dimensional change, making it an ideal choice for precision parts with tight tolerances where added thickness from other coatings would be problematic.
Our Solution: We design our blackening lines with integrated fume extraction and wastewater treatment options, helping manufacturers meet stringent environmental regulations and operate more sustainably, reducing their ecological footprint.
Our Solution: Beyond aesthetics and corrosion resistance, our blackening lines can be configured to impart additional functional properties. For instance, oil post-treatment enhances lubricity, which is beneficial for moving mechanical parts, providing a multi-functional surface.
Roller plating and blackening equipment production line is a kind of production line integrating roller plating and blackening treatment, which is mainly used for electroplating and blackening treatment of metal surface to improve the corrosion resistance, beauty and functionality of metal. The following is a detailed introduction of roller blackening equipment production line:
I. Overview of the Production Line
The barrel plating and blackening equipment production line usually consists of pre-treatment equipment, barrel plating equipment, blackening treatment equipment, cleaning equipment, drying equipment and testing equipment. The production line adopts advanced plating technology and blackening process, which can realize efficient, uniform and stable plating and blackening treatment of metal surface.
II. Main Equipment
1. Pre-treatment equipment: including oil removing, rust removing, acid washing and other processes, which is used to remove oil, rust and oxides on the metal surface and provide a clean substrate for the subsequent barrel plating and blackening treatment.
2. Roller plating equipment: Adopting the roller plating method, the metal parts are evenly rolled in the plating solution by the rotation and turning of the rollers, so as to realize the plating treatment on the metal surface. Roller plating equipment has the advantages of high production efficiency, uniform plating layer, saving plating solution and so on.
3. Blackening treatment equipment: After the completion of barrel plating, the metal parts are sent to blackening treatment equipment for blackening treatment. The blackening treatment usually adopts oxidation or chemical conversion methods, so as to form a dense layer of oxidation film or chemical conversion film on the surface of the metal, thus improving the corrosion resistance of the metal and the aesthetics.
4. Cleaning equipment: used to clean the metal parts after roll plating and blackening treatment, to remove surface residues and impurities, to ensure the quality of plating and blackening layer.
5. Drying equipment: used to dry the cleaned metal parts to prevent the residual moisture from adversely affecting the plating and blackening layer.
6. Testing equipment: to test the products of each process on the production line to ensure that the quality of the products meets the standard requirements.
