Rust takes a rest
) processes of chemical rinses and surface treatments. MetalJacket coating system does away with all that. It instead "autodeposits" barrier coatings without high voltage, rinses, or the heavy metals of the ubiquitous zinc-phosphate plating process. Lord says MetalJacket aqueous coatings contain no hazardous

AlliedSignal Automotive Brake Division Improves Productivity with ARMEX(R)
AlliedSignal Automotive Brake Division manufacturers 50,000 castings a day as a tier one supplier to the "Big Three" automotive companies. Most of the castings (made from ductile iron at this foundry) are key components of automobile brakes, such as the housing and calipers. These castings are made

AFS Castings of the Year
and the need for stress relieving. , Mankato, Minn., engineered an austempered ductile-iron and ductile-iron green-sand casting from a weldment. The new assembly was 30% lighter and cost 40% less. In a Static Mixer Tube, , Waukesha, Wis., made an abrasion resistant, 124-lb white-iron no-bake sand casting

Babbitts
compatibility properties under boundary lubrication. In small bushings for fractional-horsepower motors and in automotive engine bearings, babbitt is generally used as a thin coating over a steel strip. For larger bearings in heavy-duty equipment, thick babbitt is cast on a rigid backing of steel or cast iron

Zing Electroplating
Zinc and its alloys have been used for over. a hundred years as protective and decorative coatings over a variety of metal substrates, primarily steel. Over the years there have been a number of processes developed for applying zinc coatings depending on the substrate, coating requirements and cost

Zinc
Zinc, a crystalline metal with moderate strength and ductility, is seldom used alone except as a coating. In addition to its metal and alloy forms, zinc also extends the life of other materials such as steel (by hot dipping or electrogalvanizing), rubber and plastics (as an aging inhibitor

Brushless DC Motors
. Trapezoidal-powered motors develop about 10% more torque than those on sine-wave power. Sinusoidal-powered motors, however, exhibit less torque ripple and operate smoother at low speed. Thus, sinusoidal-powered motors are often used for machining, grinding, coating, and other operations calling for fine surface

Not your average carbon copy
in strength and durability. Designers producing parts from aluminum, bronze, brass, and cast iron have an alternative: Graphite permanent molding (GPM). As one of the "permanent" mold processes, GPM falls into the same category as die casting. The process uses one mold to make many parts. This contrasts
