Working all over the world, Van Steel has seen a similar sight at fabrication facilities and construction sites: drums and buckets filled with oxyfuel and plasma cutting tips that have been thrown away because it was easier to do that than clean out the blowback slag. He has developed a tool to make that job easier.

Forming products from advanced high-strength steels is a challenge. Understanding how these materials react during press feeding, straightening, blanking, and forming is necessary in designing production processes that run as efficiently as possible.
Editor’s Note: This article is Part II of a two-part series. Part I, which appeared in the November/December 2016 issue, discussed the challenges of determining Young’s modulus, one of the most important parameters for springback prediction.

Many skilled-labor jobs continue to go unfilled. To help alleviate the shortage, more programs are being designed to attract women to the trades. Cultivating a safe manufacturing environment that offers fair, equal wages also can help.

Some stamping plants and die-building facilities are far more productive and efficient than others. Each shop typically has its own niche, as well as its own strengths and weaknesses. So what are the key decisions managers make that result in a successful stamping or die-building shop? Staffing...

Q: We are developing what we thought would be a fairly straightforward stamping. We are blanking a rectangular shape, 2.15 by 2.35 inches and 0.004 in. thick, from 301 stainless steel. A simple, single punch blanks the part through the die chase in one shot. But as we brought up the stamping speed...

When considering a retrofit to an older plasma cutting table, a fabricator needs to consider equipment location, state of table components, the types of shielding gases and consumables that might be needed with a technology upgrade, and any possible training that may be needed.

Good estimating involves more than just numbers crunching. A good estimator needs to communicate and collaborate with various people, from the owner to the machine operator. That person also needs the right organizational structure and technology in place to be effective.

The future of work in metal fabrication may be less about a specific task and more about uncovering better ways to satisfy customer demand and get the job done.

How do you define “continuous improvement”? Turns out, it depends on your organization and your role within it. Altogether, the mix of continuous improvement perspectives within a company should strike a balance between two concepts: efficiency and effectiveness.

Laser cutting with nitrogen as an assist gas is still the No. 1 choice for applications in which edge quality is critical. Air as an assist gas, however, might work in some not-so-critical applications, and its use will generate sustainable cost and time savings while boosting productivity.

Fabricators that cut a lot of aluminum extrusions probably end up with plenty of scrap. Traditional thinking suggests that’s not so bad because recyclers pay them for the aluminum scrap. Over the long term, however, that thinking is costing them money. If fabricators can minimize scrap, they can maximize revenue because that raw material, once destined for the scrap bin, will be transformed into something of high value. Optimization software and cutting automation can help fabricators keep their material out of that scrap bin.
