Metal Stamping utilizes mechanically or hydraulically powered presses
ranging in size from those required to form small electronic components to huge
presses used in the production of large automobile and airplane panels.
Continuous strips of metal or individual blanks are positioned in the press and
shaped between tooling forced into the materials by a powerful ram. Look at a
simple desk stapler - It forms parts in the same way that a press does!
Sheet Metal Fabrication covers a variety of metal forming operations such
as Press Brake, CNC Turret Punch Press, Laser Cutting and welding. Most Press
Brakes are manually fed by an operator who holds a metal workpiece between a
punch and die and against a gauge to provide a pre-set bend or series of bends
in the metal, making it ideal for producing bent parts such as enclosures and
cabinets. A CNC Turret Punch Press is used to sequentially punch a series of
shapes or parts, following a computer-controlled blueprint. Laser Cutting uses a
powerful, highly focused beam of computer-guided light to fashion desired shapes
from materials up to ½" thick.
Slide Forming is a continuous stamping process that can convert metal
strips or wire into small intricate curved shapes, such as springs and
electronic connectors. Stock is fed into the slide-forming machine where it is
cut into blanks and then bent around a mandrel by a number of cam driven forming
tolls to create a desired shape.
Metal Spinning produces hemispheres, cones, venturis and other similar
shapes from flat metal discs or blanks which are rotated on a lathe and pressed
against a tool to duplicate its shape.
Roll Forming is a continuous bending operation where a sheet or strip of
metal passes between one or more sets of rotating dies such as channels, angles
