How to gild your safety record

July 13, 2016

Talan Products has consistently reduced its safety incident rate since 2006. That it has manufactured for 1,600 days without a lost-time accident is no accident. It is the result of a deliberate development of an omnipresent safety culture. Other manufacturers often ask, “How do you do it?” The manufacturer shares its safety secrets, including establishing a safety culture, learning from near-misses, using sensors, and tracking safety metrics.

High-speed stamping quenches thirst for beverage cans

July 13, 2016 | By Greg Stueve

All of the components of a beverage can are stamped in a high-speed press. The process of producing two-piece beverage cans starts with the blanking and forming of a cup from a large aluminum coil. Today’s most advanced cupping presses can run a 14-out die up to 350 strokes per minute (SPM), producing up to 4,900 cans per minute. Would soda beverages be as popular if they could not be packaged in a portable, singular, recyclable can made inexpensively by a high-speed stamping process? Some unique challenges and critical factors for press work in high-speed can stamping include high operating speeds, dynamic balancing, and off-center loading. Here are some ways to handle stamping at (almost) the speed of light--and takeaways for slower operations.

Fabricating long coils rather than short straights

July 11, 2016 | By Wynn H. Kearns

Most fabricators work with standard lengths of straight tube, but this isn’t the only possibility. Many alloys are available in coiled form, can lead to faster processing, better use of floor space, and increased material yields.

Coil-fed fabricating

July 11, 2016 | By Dan Davis

Most manufacturers associate coil processing with the metal forming industry. They also likely assume the punching and laser cutting combination machines consume sheet metal. Elleci S.p.A., a metal fabricator in northern Italy, has a new line in place that will require many manufacturers to alter their preconceived notions about coil consumption in a fabricating facility.
