from 25% to 45%. The use of the PS&T Brand HyperFlow Process has
allowed metal finishers to achieve variabilities as low as 8%. (The actual
results will, of course, vary based on part type, processing conditions,
thickness testing equipment and thickness testing protocols.)
Based on considerable history in evaluating Mechanical Plating and Mech-
anical Galvanizing, representative comparative examples are as follows:

HyperFlow’s Features, Advantages and Benefits
nImproved Industrial Hygiene. The HyperFlow metal slurry system greatly
reduces operator exposure to dusty airborne plating metals.
nImproved Thread Profiles - Both Internal And External. In the HyperFlow
Process, each particle of plating metal is completely dispersed before it is
charge to the plating barrel. Therefore, the resulting thread profile is much
more uniform and much smoother. Internal threads have sometimes been
a problem for mechanical platers. With external threads, the plater may rely
on the mechanical energy imparted by the parts and the media to break up
agglomerates. This is not always the case when plating internally threaded
fasteners; occasionally there are aggregates of coating in the thread roots.
These are the result of depositing agglomerates of plating metal. This
problem has occasionally manifested itself in driveability problems.
nImproved Metal Utilization. Thickness requirements are usually stated with
a minimum requirement that must be met by a large percentage of the parts.
Because the coating thickness variability has been minimized, this require-
ment is achieved with less plating metal.
nBetter Consolidation. "Consolidation" is the term used by Mechanical
Platers and Mechanical Galvanizers to refer to the essential process of
mechanical deposition - the flattening and "cold welding" of particles of a soft metal to the substrate. By assuring that each particle is separately de- posited, the consolidation is significantly improved.
nMore Consistent Salt Spray Results. More uniform coating weights and
coating thicknesses obviously translate into more consistent salt spray
nReduced Waste Treatment Costs. With less metal powder required
because of improved metal utilization, less metal goes into the waste treat-
ment system, resulting in lower costs.
nBrighter Chromates. Chromate coatings are thin and transparent. Because the underlying deposit is smoother and brighter, the chromate
coating is also smoother and brighter.
n Less Expensive. Improved metal utilization coupled with the resulting lower waste treatment costs and fewer rejects means that this new, improved process is significantly less expensive than older processes.
nExceptionally Consistent Mixed Metal Deposits. Many mechanical
deposits utilize zinc with admixtures of tin to provide lubricity and to reduce
white corrosion products. For many platers, achieving a uniform con-
sistency using dry mixing processes has been difficult. PS&T’s revolutionary new HyperFlow Process, with its uniform liquid mixture, assures platers of
consistent metal ratios.
How The PS&T Brand HyperFlow Process Works
In the PS&T HyperFlow Process,the plating metal is first mixed with water
and a proprietary ‘Carrier’ to produce a slurry. This slurry is then introduced into the plating barrel, either manually or through the use of a pump. The pump can be operated manually or under the control of a digital processor
or personal computer. The proprietary chemistry of PS&T’s HyperFlow
Carrier prevents the plating metal from settling and otherwise helps to
produce a smooth, uniform deposit. The concentration of plating metal can
be as low as one pound per gallon or as high as ten pounds per gallon.

the tank, and pump the slurry over a fifteen or twenty minute period into
the plating barrel. This frees the operator to perform other tasks while
the metal is being added to the barrel, and the cost - under two
thousand dollars - is quickly recoverable from reduced labor costs.
