temperature on the griddle means every burger is repeatable, with con- sistent quality and no undercooking. While Hostert said 80% of the
design work at CAS revolves around the heating element, achieving a consistent cast part around that element is also crucial. CAS devel- oped PLC controls to monitor and

augment key factors in the casting process, such as mold temperature, cycle times and the pressure used to eject the metal. “A lot of the applications, such
as wafer manufacturing, take place under vacuum and deal with poten- tially hazardous chemistry,” Meadors said. “Tese industries strive for

safety and our heater is a part of this. It can’t leak under a vacuum. We’ve incorporated very robust monitoring and control mechanisms in-house, from X-ray and ultrasound testing to infrared and helium leak testing. We take no chances with quality.” CAS, which employs 75 people,
operates eight low pressure per- manent mold machines and four tilt-pour permanent mold machines to cast parts up to 100 lbs. It pours 319, 356 and pure aluminum. Pure aluminum is used for the semicon- ductor parts. CAS’s customer base is balanced
among four main industries: food, medical, semiconductor and oil and gas. It also serves a range of other industries on a smaller scale. “Like all companies, we have
aggressive growth targets, and as the economy or a particular industry slows, it has an impact on us,” Ahern said. “Tat being said, we utilize our growth metrics as a way to challenge ourselves to find new customers and new industries.” Industries like medical and
semiconductor are regularly improve their equipment, which means CAS has substantial repeat business. “Our customers constantly update

their machines,” said Jeff Awe, CAS marketing director. “So we always have a fair amount of new jobs from established customers. At the same time, we’re regularly contacted by startups, development engineers and firms in emerging industries.” CAS has a large engineering staff
that acts both to design the parts and as an extension of customer service. “The customers come to us

with problems and ask us to come up with a solution,” Hostert said. “We encourage our customers to be involved early and that usually saves everyone money.” OEMs are usually not as well-
versed in thermal engineering as CAS, so they rely on the supplier to come up with a way to achieve the desired temperature within the desired dimensions. To further enhance company
growth and balance the product mix, CAS offers a standardized line of
