Horsch Maschinen GmbH, an agriculture implements manufacturer, experienced corrosion problems related to the tubular couplers used for its hydraulic systems. It switched to couplers manufactured by Voss Fluid GmbH, which are much better at standing up to the corrosive effects of common fertilizers.

Top Fuel races are a dazzling sight, covering 1,000 feet in little more than 3 seconds. The drivers get the glory and the engines get the attention—they develop approximately 10,000 horsepower—but underneath the car’s exterior is a marvel of modern engineering: a tubular chassis that somehow holds together through 4G of acceleration during the race and the even harsher 5G of deceleration when it’s over.

When A.O. Smith, the company known for developing the glass-lined residential water heater, had a bottleneck at its resistance welding station and sought an alternate welding method. It had been making a lap welding on galvanized steel by resistance welding, but this trapped vaporized zinc; escaping vapors weakened the weld. A new method, a butt weld performed by laser welding, doesn’t trap the vapors, leaving a visually appealing weld that is essentially free of defects.

Preparing tube or pipe ends for welding with a portable tool is one way to get the job done, but for complex end forms and high-volume work, a stationary beveling machine is the way to go.

Before Thom Shelow founded Superior Joining Technologies Inc., he did quite a variety of welding, but his welding experience wasn’t the only asset he used to make the business a success. He keeps an open mind and is always ready to analyze new ideas, new concepts, and new technologies. “That’s the way we’ve always done it” doesn’t prevail at SJTI.

In 1973 full-time farmer Mike Van Mill tried his hand at building a grain wagon for a neighboring farmer, and he has been at it full-time since incorporating Brent Industries a few years later. Now the operations manager for Unverferth Mfg., Shell Rock, Iowa, Van Mill is part of a team that manufactures implements under the Brent brand name. The staff runs the facility like a savvy farmer runs a farm, always looking for a better way but proceeding cautiously. A sheet laser purchased in the early 2000s led to a tube laser purchased in 2014.

Former toolmaker Toolspec Manufacturing Co. has transitioned over the years to become a fabricator, and over the years acquired 14 hydraulic benders. The machines are capable but require lengthy tool changeovers, hours of programming time, and substantial expertise to maintain bend consistency. It recently invested in two all-electric machines, benders that don’t have these issues.

For structural fabrication-and-construction companies, efficiency in logistics is vital. A typical column, beam, truss or joist is handled three times—first to a storage yard, then to a staging area, and finally to the semitrailer. However, this isn’t the only way to do it. Reinicke Athens Inc. recently invested in a straddle carrier from Combilift Ltd. Instead of moving one part at a time, the truck lifts and moves an entire load a time, cutting its trailer-loading time from up to 8 man-hours to as little as 30 minutes.

An update from an article that ran in the September 2013 TPJ, this column describes a research project intended to help eliminate trial-and-error setups, conserve programmers’ time, and help get products to market faster by helping everyone involved in a bending project home in on the optimal bending process before getting started.
