Two ways to be right.

The pages of MODERN CASTING are filled each month with ways
metalcasters can improve their efficiency and bottom line. As is
regularly cited on this editorial page, automation often is key to
enhancing productivity, increasing consistency and reducing labor.
The statement seems to be a given. In today's bigger, better,
faster world, the emphasis always is on growth and how we can achieve
more. Growth equates to success.
But for some metalcasters, the "art of metalcasting" is
paramount over efficiencies in production. The skills and practices
required to design a gating system that will quiescently fill a nobake
mold for an aerospace component that must pass x-ray inspection are the
focus rather than the number of molds or castings produced per hour. Our
industry has two faces--80% must learn to thrive in the bigger, better,
faster world while the other 20% must focus on every casting (and every
inch of every casting). Each must thrive for the industry as a whole to
succeed.
Our 2008 Metalcaster of the Year, Signicast, exemplifies the latest
in automation and technological innovation. Look to the article on p. 18
and see the use of robotics in wax injection, ceramic shell build and
pouring. Survey the automated systems that transport wax trees, ceramic
molds and castings, and check out the driverless fork trucks. Read about
the process advancements in wax production, automated pouring and lead
times. Signicast has taken manufacturing engineering and casting
production to a new level, defining what most (the 80%) of today's
job shop manufactures must aspire to become.
Over the years, opinions and mindsets change. In fact, several
years ago, I would have argued that Signicast is what all metalcasters
must aspire to become. I would have stated that continual technological
breakthroughs were the only true way to thrive in this global
marketplace. But today, my thoughts have changed, in part because of a
recent visit to a metalcaster in the other 20%.
AlumAlloy Co. in Ontario, Calif., re-opened my eyes to the
craftsman portion of our industry. From the engineered methods used to
time the pouring of a mold to the way chilis and parting lines were
employed to ensure defect-free components, this metalcaster employed
process ingenuity to produce quality castings. While none of the tools
or technology employs would be considered advanced (not even close), the
firm is engineering its castings to its customers' satisfaction.
Its customer base doesn't need high production. It needs short runs
of large, x-ray quality aluminum components, and this niche will be
protected in the global manufacturing environment.
Can the art of metalcasting coexist with production-intensive
technology? Sure it can. We just need to make sure our customers realize
that two solutions might exist for their engineered component needs.
