Custom Sheet Metal Forming Services in Jamestown, NY

Sheet metal Forming Services


If you’re looking for a sheet metal forming company that offers a variety of forming services, expert engineering consultations, and up-to-date machinery to accommodate any and all of your projects — Blackstone is the company for you.

Our press room has accommodations for any project, regardless of the dimensions, and for any metal forming service you require. Including:


Sheet Metal Bending

Sheet metal bending describes the process, usually involving a punch die setup, that enacts both compression and tension in order to alter the part’s shape without changing the volume.

Bending processes differ due to the shape, size, and thickness of the piece of sheet metal in question. Other considerations include:

  • Size of the bend
  • Bend radius
  • Angle of the bend
  • Location of the bend in the sheet meal

Working with a sheet metal expert who can talk you through the ins-and-outs of sheet metal bending is integral to ensuring you end up with the perfect part every time.


Sheet Metal Rolling

Sheet metal rolling works by placing a sheet of metal in between the compressive forces of two constantly spinning rolls. The main goals of sheet metal rolling are to:

  • Reduce the thickness — The reduction in sheet metal thickness is measured by a value known as draft. While the draft changes, the volume of the sheet metal ultimately remains the same.
  • Affect the grain structure — During the sheet metal rolling process the cast grain structure is transformed into a wrought grain structure. This allows a more uniform structure in the metal, and decreases issues such as porosity by closing up cavities within the original grain.

As with most metal fabrication processes, you risk defects when sheet metal rolling. Always work with an expert sheet metal fabricator you trust to ensure product perfection time and time again.


Press Braking

Press-brake bending is a process that involves modifying the shape of the sheet metal part. This is done through precise angles of the tools (both top and bottom) within the brake, as well as the pressing force and speed of the brake itself.

There are several types of bending that can be accomplished with a press brake:

  • Folding
  • Wiping
  • Air bending
  • Bottoming

A lot of factors go into successful sheet metal press brake pending — including pressure, tonnage, working length, distance backgauge, work height, stroke, speed, and more.

Make sure to always talk with your sheet metal fabricator about the detailed specifications for your project, so they can ensure the proper bend is accomplished with a press-brake.


Sheet Metal Stamping

Sheet metal stamping describes a process in which sheet metal is cut and then subsequently formed. Most commonly, sheet metal stamping is done through cold forming operations. However, there is a process known as hot stamping where heat is introduced to the process.

There are two types of sheet metal stamping presses: hydraulic and mechanic. Both of the presses utilize “dies” in order to create stamped parts.

Sheet metal stamping is a great cost-effective option for those looking to produce a large quantity of metal fabricated parts. Through our use of VAVE Engineering (and cell manufacturing) we are able to keep costs down for customers throughout our processes.
