Featured Custom Solution
The Ipsen Vacuum Oil Quench (VOQ) furnace, capable of both gas and oil quench, offers the perfect
balance of flexibility and quality to meet your most rigorous uptime requirements. The VOQ doesn’t
require an endothermic gas generator or carbon probes and doesn’t need to be idled when not in use.
The furnace is not only safe and environmentally friendly, but also has a low gas (heating and process
gas) consumption rate and low maintenance costs.
The versatile VOQ can handle a multitude of thermal processes and materials including:

Automotive Buzz
The health of many of our businesses rises and falls (at least to
some extent) on the trends in the automotive industry. So how
is the industry doing? What’s the buzz out there, and what is
driving growth?

The Arcane World of CAFE Standards
14
It is estimated that 220,000 American jobs will be lost due to
CAFE (Corporate Average Fuel Economy) standards, which will
also cost every new-vehicle buyer some money. And the auto
industry will spend an estimated $135 billion to comply.
Why do CAFE standards exist?

Masking Techniques (Part 2)
We continue our discussion from last month on where, why and
how masking methods are used to protect part surfaces from
oxidation or limit the areas on a component part where a case-
hardening process is to be performed. 16

Adiabatic Flame Temperature
There are at least two ways to describe a furnace’s thermal
performance. The percent-available heat indicates thermal
effi ciency, while the adiabatic fl ame temperature indicates heat-
transfer intensity. Both factors can be used to indicate a furnace’s SPECIAL SECTION
productivity.
