Sheet Metal Fabrication Services - Cutting, Bending, Rolling, Forming, Stamping and Welding

Sheet metal fabrication services providers manufacture components by cutting, bending, rolling, forming, stamping and welding sheet metal. Components manufactured through sheet metal fabrication services are used in a variety of applications such as enclosures, computer equipment, HVAC components, kitchen and sanitary equipment, machine tools and other industrial applications. Sheet metal fabrication services include a diverse range of processes used to fashion sheet metal into usable products. These processes may be broken down into rough categories, cutting, forming, and finishing services. Sheet metal fabrication services include conventional PU painting, Hot Stamping, Screen Printing, Pad Printing, Induction Welding, Electroplating, etc.

Sheet metal is one of the most important semi finished products used in the steel industry, and sheet metal forming technology is therefore an important engineering discipline within the area of mechanical engineering. Sheet metals are characterized by a high ratio of surface area to thickness. Sheet metal forming is basically conversion of a flat sheet metal into a product of desired shape without defect like fracture or excessive localized thinning. In automobiles the sheet metal is deformed into the desired and brought into the required form to get auto body pressings like bonnet, bumpers, doors, etc. In aircraft's sheet metal is used for making the entire fuselage wings and (body). In domestic applications sheet metal is used for making many parts like washing machine body and covers, iron tops, timepiece cases, fan blades and casing, cooking utensils, AC, etc. Electrical appliances are gadgets that run on electric motors and are widely used in households for convenience, to reduce manual work and to save time. Some examples of appliances are refrigerators, washing machines, air conditioners, microwave ovens, and vacuum cleaners.

Sheet metal fabrication are used in a variety of applications

The products made by sheet-forming processes include a large variety of shapes and sizes, ranging from simple bends to double curvatures with shallow or deep recesses. Typical examples are metal desks, appliance bodies, aircraft panels, beverage cans, auto bodies, and kitchen utensils. In many cases while deforming the sheet metal, the component fractures at certain point. The causes of failure are parameters related to forming process. Traditional evaluation of formability is based on both intrinsic tests and simulative tests. The intrinsic tests measure the basic characteristic properties of materials that can be related to their formability. These tests provide comprehensive information that is insensitive to the thickness and surface condition of the material.

Sheet metal fabrication services include conventional PU painting, Hot Stamping, Screen Printing, Pad Printing, Induction Welding, Electroplating, etc.

PU painting :

PU painting is one of the processes for sheet metal fabrication services. Coatings based on polyurethane resins, having good adhesion to metal and nonmetal surfaces, are characterized by high indices: resistance to abrasion, hardness, and flexibility, and are also distinguished by resistance to weathering, resistance to oils and solvents, water resistance in fresh and sea waters, gas impermeability, and high dielectric properties.

Hot Stamping :

Hot stamping equipment is available in different styles, sizes & specifications for use in for automotive & non-automotive applications. Hot stamping is defined as a dry printing process, which uses controlled heat, pressure, and precision timing to transfer a color pigment from foil to surfaces of varied shapes and materials. This process forms a permanent bond between the part and the foil, and creates a dry print. The advantages of hot stamping include increased productivity, multiple colors in one step, and a variety of available materials and finishes.

Screen Printing :

Screen Printing is a printing technique that uses a woven mesh to support an ink-blocking stencil. A screen is made of a piece of porous, finely woven fabric called mesh stretched over a frame of aluminum or wood. Originally human hair then silk was woven into screen mesh; currently most mesh is made of man-made materials such as steel, nylon, and polyester.

Pad Printing :

There are various pad printing services: single color pad printing, multicolor pad printing, and high volume pad printing. Pad printing can successfully decorate three-dimensional parts because while transferring the image to the part, the silicone pad wraps around or adapts to the shape of the part without distorting the image, given some image size restrictions. Extremely fine detail and tight multicolor registration are readily achievable with pad printing.

Induction welding :

Induction welding is a form of welding that uses electromagnetic induction to heat the work piece. The welding apparatus contains an induction coil that is energised with a radio-frequency electric current. This generates a high-frequency electromagnetic field that acts on either an electrically conductive or a ferromagnetic work piece.

Electroplating :

Electroplating services including plating for chromium, copper, gold, nickel, silver, tin and zinc. Metal polishing and metal passivation, measurement testing and solution testing.
