Sheet Metal Forming Service

Introduction
Sheet metal forming is a manufacturing process in which a piece of sheet metal is plastically deformed into a desired shape. The sheet metal is typically cut to size before being formed. The forming process can be done using a variety of tools and machines.

Nhat Nam Mechanical provides different sheet metal forming processes, each of which is used to create a specific type of shape. Some of the most common sheet metal forming processes include:

Bending: Complex parts such as Usections, channel sections of different profiles can be produced by doing multiple bends. There is no change in thickness. Good dimensional repeatability as well as close tolerances is possible with this process.

Nhat Nam uses several different types of press brakes to create formed and shaped pieces, ranging from 50 to 100 metric ton capacities. CNC operated, these systems create accurately formed parts quickly, and with the tight tolerances, our customers have come to expect.

Stamping: Usually done with a flat sheet of cold metal, Stamping, also known as pressing, is the process of creating a net shape out of metal using a tool and die surface. There are many other metal stamping processes such as embossing, bending, flanging, punching, etc. that we use to when working our customers

Depending on the need of the customer, we can use progressive dies that are typically fed material via coil of steel. After it is unwound, it is then leveled and fed into the press to a predetermined length. The entire process of feeding the metal stamping with coil of steel helps in significantly reducing production lead-times. All of the benefit of our customers.

We also perform CNC tube & pipe bending, as well as rolling services for both plate and angles. We also have the capabilities to shape pipe and tube according to orders.

Stamping

Deep drawing	uses a punch to fabricate deeply-recessed parts. The depth of a deep-drawn part exceeds its width, as with a cup made from a flat metal sheet.
Blanking or piercing	operations produce stamped parts by use of a punch and die. A press is used to advance the punch tool through a sheet into the mating die. Blanking and piercing operations typically require finishing or other secondary operations in order to remove sharp edges, burrs, or other rugged features.
Fine blanking	is a specialized, high-precision blanking technique in which material is sheared smoothly through its entire thickness. Fine blanking can be used to produce finished parts that do not require secondary operations.
Fourslide or multislide	stamping incorporates the vertical motion of a punch with horizontal die applications from multiple directions, either simultaneously or successively.
Progressive dies	are used in production-efficient processes where multiple stamping or forming operations are performed in successive stages or positions along the fabrication cycle.

Insert
For custom enclosures or parts, self-clinching fasteners are probably the most useful hardware components at a designer’s disposal. They solve a whole host of challenges when it comes to mounting components, and because of their compact design and low profile, they provide excellent aesthetics as well. Themost popular are PEMS Fasteners.

If you require a fastener we don’t stock, contact us – we’d be happy to source what you need, for added lead time and cost.
