Subtractive manufacturing techniques are typical operations in sheet metal fabrication where a desired part is created by progressively removing material from a raw metal sheet.
At IMS we use Punching and Laser Cutting to process sheet metal.
The process focuses the laser beam on the material surface to burn, vaporize or melt materials and produce desired outcomes. Since it is a precise and accurate process, it makes fabricating components with intricate details easier.
Here at IMS, we use the Trumpf TLF 3200 CO2 Laser for cutting sheet metal components quickly and efficiently. We have two different laser heads; a 5” focus lens and a 7.5” focus lens used to cut through different materials and thicknesses.
A punch or punching machine uses pre-formed dies and punches to transform sheet metal blanks into formed products and parts. The punches pass through the sheet metal, while the dies are located on the opposite side of the sheet metal. As the punch moves downwards into the die, the sheet metal beneath the punch gets sheared from the surrounding material. The scrap pieces of metal that is sheared off are also known as slugs and they get collected and recycled.
At IMS, we use the Trumpf TruPunch 1000 to process aluminum sheets with thicknesses of up to ¼” inch with up to 600 strokes per minute. It can hold up to 15 different tools with various shapes and some custom made shapes for specific jobs. We also use forming tools that can countersink, half shear, louvers, and other special forms.
