What’s Press Brake Forming?

Press brake forming is a precise sheet metal bending process that uses a press brake machine to bend metal sheets into desired angles and forms. By applying controlled pressure through upper and lower dies, the metal undergoes plastic deformation, producing accurate bends with consistent quality. This bending process is widely used in prototyping and low-volume production for components in automotive, electronics, industrial equipment, and more.

Sheet Metal Material Options

Surface Finish and Post-Processing Options

Custom CNC machined aluminum container showing surface finish details

As machined

The machined or deburring finish is the standard finish where unwanted attach chips are removed with deburring tools, and sharp edges are chamfered to smooth the surface (3.2 μm).

Sandblasted surface finish on metal part showing uniform matte texture and improved surface adhesion.

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.

Anodized surface finish on aluminum part showing durable oxide layer, enhanced corrosion resistance, and decorative appearance.

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.

Alodine surface finish on aluminum part showing chromate conversion coating for corrosion resistance and enhanced paint adhesion.

Alodine

Provides excellent corrosion resistance property to the aluminum parts with greenish-gold color. It is the low-cost and quick surface finishing approach.

Metal part with polished surface finish, showing smooth, reflective texture, precision manufacturing, and high-quality finish.

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.

Metal part with brushed surface finish, showing uniform texture, enhanced aesthetics, and precision finishing.

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.

Aluminum alloy sheet and rods samples

Sanding

Provides a random, non-linear texture with a shiny, high gloss finish. However, it might be unable to create sharp corners and pockets

Metal parts with black-oxide surface finish, showing corrosion resistance, matte appearance, and precision manufacturing.

Black-Oxide

Black oxide finish reduces surface reflectivity and offers mild corrosion protection. It involves adding a thin layer of magnetite to the surface.

Sheet metal fabricated part with surface finish, showing precision manufacturing, custom metal forming, and advanced surface treatment.

Electroplating

Electroplating increases the hardness of the steel &aluminum parts. It offers excellent corrosion, wears, and abrasion resistance.

CNC machined metal part with chrome plating finish for high hardness, corrosion protection, and mirror-like surface appearance.

Electroless Nickel Plating

A thin layer of Nickel is created on the surface from a nickel-containing solution without electrolysis. Electro-less nickel plating provides a shiny appearance, excellent hardness, abrasive, wear, and corrosion-resistance to the substrate material.

CNC machined metal part with chrome plating finish for high hardness, corrosion protection, and mirror-like surface appearance.

Chrome Plating

Chrome plating is widely used in various industries, which not only enhances the beautiful appearance of the product, but also improves the performance of the product, such as corrosion resistance, oxidation resistance, abrasion resistance, hardness, etc.

CNC machined metal part with passivation finish for corrosion resistance and improved stainless steel protection.

Passivation

Enhance the appearance and functionality of the parts. After Passivation, parts of Steel and its alloys become super resistive from corrosion.
