L etter Stamps
Applications: Common applications include marking serial and/or batch numbers on parts for complete traceability, marking construction lines, center lines and datums to help with fabrication or assembly, and marking bend line information and special instructions.
ID STAMP
Applications: Consistently mark multiple numbers, letters and various symbols without ever taking the ID Stamp off your machine.
The Pen
Application: Typical applications include (but are not limited to): marking serial and/or batch numbers on parts for complete traceability; marking construction lines, center lines and datums to help with fabrication or assembly; marking bend line information and special instructions.
Dash Tool
Applications: Dash tools can be used to create numbers or letters, coining a “V” groove on bend lines to aid in the bending of the sheet, and locators on a sheet. This tool is especially useful in applications where the number or letter of the part being marked is constantly changing or progressive.
Ground Symbols
Applications: Ground symbols are widely used in the electrical industry.
Stamped Logos
Applications: Stamping a company logos and other fixed marking on sheet metal is often desirable. Custom logos or other special stamps are the solution.

How to break grain of metal?
This consists of rolling the piece of metal backwards and forwards a few times in the rolls, reversing the bending each time. This process will ensure that the article to be formed by rolling will have a smooth surface free from kinks. If this 'breaking' operation is not carried out, a cylindrical or conical article develops ridges around the shaped body which, if not seen, may be more easily felt by passing the palm of the hand over the rolled surface.
