The TOSTA blog aims to share the prototyping and rapid manufacturing knowledge, experience and skills we have accumulated over the years.

Sheet Metal Stamping

Sheet metal stamping (also known as sheet metal pressing and forming) is the process of placing flat sheet metal in either blank or coil form into a stamping press where a tool and die surface forms the metal into a net shape.

Sheet Metal Stamping Process

Metal pressing and forming include a variety of sheet metal stamping manufacturing processes, such as punching by using a sheet metal stamping press machine, blanking, embossing, bending, flanging and coining, etc. This could be a single stage operation where every stroke of the press produces the desired form on the sheet metal part or could occur through a series of stages.

The process is usually carried out on sheet metal. During the sheet metal pressings, through using highly specialized computer-aided drafting and manufacturing programs, sheet metal is transformed into complex parts. TOSTA has the most professional sheet metal pressings technology which can ensure the high quality of our products.

Part Material Selection

The Parts can be formed, stamped, or fabricated. Material options include Carbon Steel, Stainless Steel, Aluminum, or Copper Alloys.

Part Size

Preferred Part Size: Formed parts with flatbacks that are smaller than 85″ x 11″

Part Tolerances

Pierced Holes: +/- 0.003″ on the shear side of the hole
Blanked Dimensions: +/- 0.005″ on the shear side of the part
Formed Dimensions: +/- 0.010″ inside of the bend
Bend angles: +/- 1 degree

Metal stamping pressings and dies can work with various metals to diverse parts in TOSTA stamping factory. Metal pressing and forming material includes SGCC galvanized plate, SECC electrolytic plate, SUS stainless steel (model 201 304 316, etc.), SPCC iron plate, white copper, red copper, AL aluminum plate (model 5052 6061, etc.), SPTE, spring steel, manganese steel. Each metal pressing and forming material has its own advantages.

Automakers benefit from the sheet metal pressing for different parts. The dies can be used again to manufacture parts with the same size and shape. All parts are guaranteed to meet strict specifications and tolerances.

Key benefits of our metal pressing and forming include: High quality, Low Cost, long-term durability and Fast Turnaround Time.
