Why Die Designers Specify Producto Die Springs
Producto die springs are precision products manufactured on special equipment and under carefully controlled processes. All manufacturing steps are conducted under rigid quality control, inspection and testing to ensure the long service life die designers have come to expect from Producto die springs.

Design & Materials
Producto die springs feature valve quality Chrome Silicon alloy wire. And that's important if you are still using chrome vanadium alloy springs.

With Chrome Silicon die springs, you get greater tensile strength and higher maximum service temperatures. Which means, in maximum service temperatures to 450 F, there is less load loss. The higher tensile strength translates to increased cycle life over die springs from other alloys.

Delivery
Local die spring inventories assures fast, off-the-shelf super ship delivery from convenient Producto Service Centers located throughout the United States & Canada.

Materials
Producto die springs add life to your dies because they are made of high tensile strength chromium alloy steels. They withstand the heavy demands of shock loading and constant high speed deflections. In addition, this alloy enables secondary operations, such as penning, to give Producto die springs an extra performance margin. Under all stress/heat conditions, Producto die springs provide significantly greater resistance to load loss than springs made of carbon steel.

Metrics
Metric conversions are provided on pages 5-8 to assist you in selecting Producto die springs on metric-dimensioned designs.

Colors
Every Producto die spring is color coded by work range, as shown, to simplify selection specification and in-plant identification.

Shape
The round-cornered rectangular configuration of Producto die springs works harder, with less wasted energy, than round or square wire configurations. This optimum cross-section minimizes stress concentration and protects against fracturing caused by stress build-up at sharp edges.

ISO Die Springs
Producto ISO compliant die springs are engineered to precisely meet ISO 10243 specifications. These springs are centered within allowable ISO tolerance & exactly match ISO or North American Automotive Metric Standards (NAAMS) nominal size standards. Other makes just change their color of existing springs to ISO colors- not Producto.
