Fineblankng now can produce not only flat parts, but also those with 3-D features, often to size and position tolerances of less than +/- 0.025 mm. It also offers extremely high part-to-part repeatability; the first part and the millionth part are identical. A confluence of technologies has made such parts a reality.
Without something to manage and absorb pressure, a die set would cease to function properly. This is why die spring selection--which considers spring size, travel, number, and placement within the tool--is so critical.
Although many of the traditional coil-handling rules apply, processing coated coil material requires additional considerations. Stampers need to check for equipment clearances and alignment at every point where the finished material surface may contact another surface.
From the perspective of a field service professional, the choice to repair, rebuild, or look for a new press isn't that hard of a decision. It's just a matter of clearly looking at the current shape of the press and what it will take to get it up to performance specs.
In-die capabilities are an important weapon in a metal stamper's arsenal. These capabilities provide the means to create assemblies as a strip of coil quickly moves through a progressive-die setup. Weiss-Aug, East Hanover, N.J., is taking that competitive edge to the next level by offering in-die laser welding to its customer base.
A supply chain is only as strong as every link. That's why more metal formers are leaning on their material suppliers to improve their coil and sheet management. A couple of metal service centers offer up some advice for those metal stampers looking to do more.
