Finishing Options
We provide various surface finish options for sheet metal parts. If your required surface treatment is not listed below, feel free to contact us for more options.
Bead Blasted
Bead blasting produces a matte texture, removing all the marks of machining tools. It applies to ABS, Aluminum, Brass, Stainless Steel, and Steel parts.
Brushing
Brushing is achieved by applying an abrasive brush to the metal surface, which produces a unidirectional satin finish. And it is not recommended for highly corrosive materials.
Anodizing
Anodizing involves adding an aluminum oxide coating to aluminum and its alloys. The layers, which come in various colors, increase strength and shield the surface from corrosion.
Powder coating
Powder coating is the electrostatically applying of dry powder to the surface. It produces a thin layer providing excellent resistance to wear, corrosion, and abrasion.
Black-Oxide
Black oxide finish reduces surface reflectivity and offers mild corrosion protection. It involves adding a thin layer of magnetite to the surface.
Electroplating
Electroplating increases the hardness of the steel &aluminum parts. It offers excellent corrosion, wears, and abrasion resistance.
Polishing
Physical rubbing of a metal surface to create a shiny surface is called a polishing surface finish. It increases the reflectivity and does not affect the dimensional stability of parts.

What is Sheet Metal Bending?
Bending is the manufacturing process in which Sheet metal is transformed into desired shapes by applying pressure along an axis. The shape is created during the bending process through plastic deformation in the bending position.
The traditional bending machines struggle to obtain correct bending angles, and it may take a long time for them to turn at proper angles since they must undergo numerous Hits & Trial Steps. While CNC bending machines operate according to pre-programmed instructions and allow the setting of different bending angles following the desired bending positions, they are faster and more accurate.
CNC bending method produces exact dimensions according to the uploaded CAD file because this technique is more automated and accurate in bending sheet metal than traditional ones. The sheet is shaped using a hydraulic mechanism (Press brake) that the computer can fully control.
Advantages
- Complex shapes are possible, including triangles with bent corners and all types of curves up to entire circles.
- Less production time
- A high degree of accuracy on bending angle
- Less production time
- Cost-effective
- High Working efficiency
- Design flexibility
- Less post-processing
- Reduced number of parts
Types of Bending
In air bending, the outside edges of a die & punch tip are used to create the bend on sheet metal. Because it requires significantly less tonnage to bend than other forms of bending, it is the most popular among manufacturers. Additionally, air bending offers more flexibility in shape and bending radius.
Rotating cylinders with a V-Opening are used in rotary bending. It is used when a bending angle larger than 900is required. For pre-painted or damaged surfaces, it works best. The roll bending process is used for sheets and bars. The primary purpose of this process is to induce a curve shape bar into the straight plate.
Coning produces consistent bending over sheet metal workpiece like coins that are uniform in shape. It is a straightforward process in which sheet metal is stamped between the punch and die. With Coining, a small tolerance & a high degree of reproducibility can achieve. Additionally, the interior radius can be decreased to any desired level.
Folding, wiping, Joggling, and Elastomer are the other types of bending used in manufacturing.
Applications
CNC Bending is used in various industries to make several pieces of equipment and parts. Some of them include;
- Automotive components
- Pipes and tubes
- The exterior of aircraft and other parts
- Defense
- Hardware components
