Die springs are rectangular wire-based helical compression springs designed to hold 30 % more weight for a given deflection. They get their name from being used in punch press die sets, which apply pressure to keep the target item in place while the press creates a hole. If the die set provides zero or excess yield, it could damage the punch.

Die Springs are colored according to their working load. Three distinct color-coding scales have been used up till now. The JISS die spring color code scale, the American die spring color code scale, and the ISO stamp spring color code scale Sadly, these aren’t universally accepted by all manufacturers.

Most manufacturers choose blue for light loads with the least amount of pressure, green for moderately heavy-duty, gold for heavy loads, and red for extra-heavy loads with the most pressure and the least travel to solid. But you should always use the manufacturer's reference table.

GL Metal, for example, offers die springs in a variety of colors, sizes, and loads. Moreover, we may design special die compression springs for your requirements.
