Hot-dipping process

Space-Saver Filter Seffko Ltd. Northbrook, ill.

The Serfilco Super Space-Saver offers flow rates to 6,000 gph and solids loading to 168 ft* equivalent surface area, while occupying only 3’12 ft2 of floor area. Other standard features include stainless steel brackets, swing

bolts with tee handles, FRP reinforcing plate, PVC hooded base, hose with quick-connect couplings, and flow control valve. The latter, when closed, will retain pump prime when changing filter media. Self-priming centrifugal, sealless magnetic drive, and mechani- cal seal pumps of chemical-resistant plastics are standard choices. Optional features include bulk granular carbon purification chamber and motor starter.

Current Conductivity Carrier Control Environmental Plating Technology Inc. Coral Springs, Ha.

The CX 5 (Computerized Current Conductivity Carrier Control) is a plating control instrument using intelli- gent switching techniques. Used pri- marily for the plating of precious

E-Brite’” 30/30 Non-Cyanide Alkaline Copper. Our E-Brite’” 30/30 is superior to ordinary non-cyanide alkaline solutions. For example, it does the “impossible” by rack plating directly onto die-cast zinc and white metal castings as well as rack and barrel plating onto steel, stainless steel, brass and zincated aluminum. No special anodes or continuous dummy plating as with other processes. Only two addition agents versus as many as five agents with other processes. E-Brite 30/30 has excellent bath stability and is extremely simple to control.

This process is not “fresh-out-of-the- lab non-cyanide technology.” It’s a performance-proven technology that over the years has helped hundreds of users do a better plating job, while eliminating cyanide. For fur- ther details write. call or fax. 17ooO W, Lincloln Ave.

metals and highly technical specifica- tions in the field of electronics, semi- conductors, printed circuit boards, flexible multilayers, connectors, etc., CX 5 converts direct current to multi- potential, multilevel pulsing, with automatic zero time and automatic peri- odic reverse. The current potential changes according to the resistance that builds up over the cathodic surface. This leads to uniformity and reduction of grain size. The reduction of grain size is the main factor for the improvement in stress reduction, ductility, wear resistance, and porosity. Advantages include uniformity, throw- ing power, hardness, wear resistance, reduced porosity, ductility, reduced stress, adhesion, solderability, conduc-

tivity, bright deposit without brighten- ers, and corrosion resistance.


Hot-Dipping Process Battelle Columbus, Ohio

Battelle has developed a new high- speed, hot-dipping process to apply a brass coating to the steel cord used to reinforce automobile tires. In the Bat- telle process, the wire to be coated passes vertically at high speed through a nozzle filled with molten brass. The brass coating is formed when it freezes on the colder wire. Because the wire is moving through the molten metal at high speed, and its contact with the melt is brief, the brass coating is

homogeneous, uniform, and adheres tightly to the core wire. The process line consists of a pretreatment section, a wire preheating unit, and the coating and cooling sections. Coating thick- nesses are controlled by the preheating temperature, the level of molten metal in the nozzle, and the wire-feeding rate. There is no pollution related to rinsing waters.


Dry-Film Lubricant Dicronite of Minnesota Inc. St Paul, Minn.

Dicronite dry-film lubricant is a substitute for fluoropolymer lubricants in applications when a typical fluoropolymer coating is too thick or when a part shouldn’t be heated to bake on a finish. Dicronite is applied without the use of heat, binders, or adhesives, and it maintains lubricity in operating envi- ronments of between -350-l,OOO°F. It bonds with the surface, not exceeding

20 millionths of an inch, and is resistant to chipping or peeling.


Titration System Sanda Corp. Philadelphia

Sanda Corp. introduces the Fully Automated Computerized Titration System (FACTS). Designed for platers, the FACTS instrument pro-

vides rapid and accurate analysis of plating solutions in one simple meas- urement. With little or no sample preparation, the FACTS unit will pro- duce reliable results automatically. In a few minutes, plating solutions can be tested for a variety of metals, total solids (to determine impurities), and many other qualities. The Sanda FACTS unit can also be put on line to achieve maximum control over the plating process. Both the manual and on-line units require no knowledge of chemistry for operation.

Attention Copper and Brass Platers.. . SUPER-Q Additive RIN Improves Appearance and Brightness

Other Quality Products

SUPER-Q liquid additive for cyanide copper and brass plating solutions greatly improves the appearance and brightness of plated parts over a wide range of current densities - at lower temperatures than previously possible. And, SUPER-Q contains no chemicals that promote anode corrosion. SUPER-Q offers these benefits: ??Exceptional Brightness-attractive finishes for copper

and brass ??Wide Plating Range - useful in both barrel and rack

applications ??lower Cost - low temperature operation cuts heating

requirements and reduces carbonate build-up in baths ??Reduction in Nickel Required -full brightness

achieved through fine-grained deposits . . . and it won’t interfere with your pollution control system because it contains no complexing agents.
