Post-processing and finishing for parts made of sheet metal
Anodization
Anodizing is an electrochemical process that increases the thickness of the natural oxide layer on the surface of metallic materials. During this process, the material is immersed in an electrolyte solution and an electric current passes through it. This treatment not onlyimproves resistance to corrosion and wear, but also allows for a more aesthetic and decorative surface.
FEATURES
- Improves corrosion resistance
- Increases surface hardness
- Allows aesthetic customization with different colors
- Available colors: natural
MATERIALS
- Aluminium
ADVANTAGES
- Benefits include longer material life, effective weather protection, and the ability to add different colors for aesthetic purposes.
Burnishing
Burnishing is a surface finishing process that gives a dark, uniform appearance to metallic materials. During this treatment, the metal is immersed in a specific chemical solution that causes a surface reaction, creating a protective layer of oxides. This layer enhances the aesthetics of the material, giving it a sleek and professional finish, but also increases its corrosion resistance.
FEATURES
- Creates a protective layer of oxides
- Enhance aesthetics with a dark, uniform finish
- Increases corrosion resistance
- Reduces friction and improves material durability
MATERIALS
- Steel
ADVANTAGES
- Burnishing improves the durability of the material, reduces friction and optimizes weather resistance.
Peening
Shot peening is a finishing process that improves the surface of metal materials through the use of small abrasive balls. During this treatment, the balls are fired against the surface of the metal at high speed, creating a series of impacts that smooth and compact the material. Shot peening gives a uniform finish and can remove any surface imperfections.
FEATURES
- Increased fatigue and corrosion resistance
- Improved component life
- Uniform surface finish
- Removal of surface imperfections
MATERIALS
- Stainless steel
ADVANTAGES
- Benefits include increased fatigue and corrosion resistance, improving component life
POWDER COATING
Powder coating is a surface finishing processin which a fine powder is applied electrostatically to metallic materials. During this treatment, the metal is electrically charged, allowing the powder to adhere evenly. Next, the workpiece is heated in an oven, melting the powder and creating an even, durable coating.
FEATURES
- Improves the aesthetic appearance of steel
- Uniform and durable coating through workpiece heating
- Increased corrosion resistance
- Homogeneous finish without dripping
MATERIALS
- Aluminum, Steel, Stainless Steel
ADVANTAGES
- Benefits include a homogeneous finish without dripping, improving the aesthetic appeal and durability of the treated materials.
ZINCIFICATION
Galvanizing is a finishing process that applies a protective layer of zinc to the surface of metallic materials to protect them from corrosion. This process can be done by hot dipping, where the material is immersed in a bath of molten zinc, or by electrolytic processes, where the zinc coating is applied using an electric current. In addition, galvanizing offers a surface that is easier to clean and maintain, thus increasing the service life of the final product.
FEATURES
- Protection against rust and weather
- Increased durability of the material
- Improved esthetic properties
- Surface easier to clean and maintain
MATERIALS
- Steel
ADVANTAGES
- Benefits include effective protection against rust and weathering, increased durability of the material, and improved aesthetic properties.
ELECTROLESS NICKEL PLATING
Electroless nickel plating is a finishing process that involves the deposition of a layer of nickel on metal surfaces without the use of an electric current. This process takes place by chemical reaction, in which the metal is immersed in a solution containing nickel ions. The benefits of electroless nickel plating include uniform coverage even on complex surfaces, increased corrosion and wear resistance, and improved aesthetic properties.
FEATURES
- Uniform deposition even on complex geometries
- High corrosion and wear resistance
- Improved aesthetics and shine
- Power-free process
MATERIALS
- Steel
ADVANTAGES
- The benefits include effective protection against wear and oxidation, longer service life of treated surfaces and refined aesthetics.
