Die Science: 7 ways that part material affects die design and the forming process

March 16, 2017 | By Art Hedrick

I recently had an opportunity to train some young product designers. During this training session, one of the product designers brought me a print of a project he was working on. It was a contoured, deep-drawn part with many intricate features, and he had a lot of questions about the...

R&D Update: Practical use of servo hydraulic cushions in stamping operations

March 15, 2017 | By Ali Fallahiarezoodar, Darrell Quander Jr., Pratik Mehta, Taylan Altan, Ph.D.

In deep drawing, with or without draw beads, the sheet metal blank is restrained at the periphery of the die by the blank holder force (BHF). The relative motion between the punch and the die forces the metal to flow into the die cavity (see Figure 1). The quality of the formed part is determined...

Ask the Expert: Which equation adds up to smooth strip feeding in progressive dies?

March 14, 2017 | By Thomas Vacca

Q: Many people believe that the feed height = passline height. But the way I learned it, feed height + lift height = passline height. If feed height + lift height = passline height and you feed the material, when the die closes, with the stock check open, the material will be pushed down by the...

Die Science: Finding the true cause of poor-quality parts

March 13, 2017 | By Art Hedrick

As a professional consultant, I find it both amusing and frustrating how many times dies are accused of being “bad.” Certainly, poor-quality dies exist. In my career I’ve seen dies that are well-engineered, precision tools, and I’ve seen dies that might as well have been made from sawdust...

Die Science: Open wall angles versus vertical walls

March 10, 2017 | By Art Hedrick

All too often designers employ open wall angles simply because they’ve been told that they are easier to form than vertical walls. Although this statement may be true for many part geometries, it is certainly not true for all. Sometimes a draft angle can be desirable; other times it can be...

Die Science: Maximizing tool steel life

March 9, 2017 | By Art Hedrick

One of the questions I get asked most frequently is “What is the best tool steel?”To me, that’s like asking, “How long is a piece of string?”There is no “best” tool steel. To choose the appropriate tool steel for a given application, you need to consider all of the situations and...

Advancements in furnace design improve hot stamping

March 9, 2017 | By Borek Dvorak, Jad Tawk

New roller furnaces for hot stamping have been designed using finite element method (FEM) analysis for numerical simulations of heating processes and heating power distribution. The advanced designs focus on optimal heating, modern roller drives, a new approach to the furnace’s input and output without movable parts, and other items with respect to the optimal technological and technical aspects to enhance the ability to perform nonuniform (Taylor) tempering and hardening.
