Understanding your needs
Surface Finishing
Finishing is generally the last or final step in the manufacture of components or at the final step of an operation of the component wherein the requirement is the highest quality in terms of accuracy, form, and surface integrity. Fine finishing that will be adding a functionality to the surface of the workpiece to enhance its quality characteristics.
Evercon has the in-house capacity for doing different types of surface finishing operations and supplies high-quality finish goods to its customers.
Finishing technology is used as a value-added manufacturing process to achieve the desired surface quality, geometric form, and accuracy. It typically removes a very small amount of material, on the scale of a micrometer or less.
Finishing processes basically follows previous material-processing and machining operations. The finishing technology also often encompasses both dimensional control and control of surface integrity including surface texture.
There are many ways of achieving surface finished components such as grinding, sand and grit blasting, buffing and polishing, painting, powder coating, thermal treatment and anodizing.
Grinding
Grinding is the most common form of abrasive machining. It is a material removal process in which the abrasive tool been used whose cutting elements are grains of abrasive material known as grit. These grits have sharp cutting tips, higher hot hardness, chemical stability, and better wear resistance.
Evercon adopted different types of grinding process w.r.t. orientation and workpiece and supplied the quality component to end users.
The grits are bonded to give a shape to the abrasive tool.
A grinding wheel implies two types of specification.
Dimensional accuracy
Good surface finish
Sand Blast & Grit Blast
Evercon uses both type of abrasive blasting, i.e., sand blasting as well as grit blasting as per the requirement and client’s specification for finishing.
What is abrasive blasting?
Abrasive blasting is a technique that creating surface textures by the impact of hard particles. Sand blasting is also known as abrasive blasting, which is a generic term for the process of smoothing, shaping and cleaning a hard surface by forcing solid particles across that surface at high speeds; the effect is similar to that of using sandpaper, but provides a more even finish with no problems at corners or crannies.
Sandblasting equipment typically consists of a chamber in which sand and air are mixed. The mixture travels through a hand-held nozzle to direct the particles toward the surface or work piece. Nozzles come in a variety of shapes, sizes, and materials. Boron carbide is a popular material for nozzles because it resists abrasive wear well.
The particles hit a metal surface at high velocity, causing localized plastic deformation. The resulting texture is influenced by the shape, size, hardness, and velocity of the shot particles using high speed particles.
Grit blasting is another form of abrasive blasting operation in which solid particles (abrasive material) forced across the workpiece surface at high speed for the process of smoothing, shaping, and cleaning the workpiece surface.
Buffing and Polishing
Polishing and buffing are finishing processes for smoothing a workpiece’s surface using an abrasive and a work wheel or a leather strop. Technically, polishing refers to processes that uses an abrasive that is glued to the work wheel, while buffing uses a loose abrasive applied to the work wheel. Polishing is a more aggressive process, while buffing is less harsh, which leads to a smoother, brighter finish.
A common misconception is that a polished surface has a mirror-bright finish, however, most mirror-bright finishes are actually buffed.
Evercon Group uses the buffing and polishing processes to provide smooth surface to the workpieces produced for the clients.
The removal of oxidization from metal objects is accomplished using a metal polish or tarnish remover; this is also called polishing. To prevent further unwanted oxidization, polished metal surfaces may be coated with wax, oil, or lacquer. This is of particular concern for copper alloy products such as brass and bronze.
Evercon uses different types of high-end structure paints as per the client require like-as –
- Acrylic finish paint
- Epoxy zinc rich paint, high build
- Alkyd resin finish paint
- High-solid modified anti-corrosive epoxy polyamide paint
- Acrylic aliphatic polyurethane paint (non-yellowing)
Painting & Coating
A coating is a covering that is applied to the surface of an object, usually referred to as the substrate.
Paints and lacquers are coatings that mostly have dual uses, which are protecting the substrate and being decorative and the paint on large industrial pipes is for preventing corrosion and identification e.g. blue for process water, red for fire-fighting control.
Functional coatings may be applied to change the surface properties of the substrate, such as adhesion, wettability, corrosion resistance, or wear resistance.
A major consideration for most coating processes is that the coating is to be applied at a controlled thickness, and a number of different processes are in use to achieve this control, ranging from a simple brush for painting a wall, to some very expensive machinery applying coatings.
Powder Coating
Evercon can supply the finished goods to clients including the powder coat requirement with mentioned RAL codes.
It can be supplied in both requirement whether glossy finish and Matt finish.
What is Powder Coating?
Powder coating is a type of coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light. The powder may be a thermoplastic or a thermoset polymer. It is usually used to create a hard finish that is tougher than conventional paint.
Anodizing
It is an electrolytic process of oxide coating, generally on Aluminum and its alloys.
Evercon uses the anodizing process for the Aluminum profiles for the machine assembly parts with thickness variation of 5 – 25 µm which give improved surface resistance to wear and corrosion.
