philosophy has always been founded and driven by four basic principles:
(1) HARD WORK
BY A DEDICATED STAFF.
(2) ATOTAL COMMITMENT TO PLATING EXCELLENCE.
(3) IDENTIFYING THE UNIQUE NEEDS OF OUR CUSTOMER.
(4) QUALITY SOLUTIONS TO COMPLEX PROBLEMS.
All of these
qualities have made DAV-TECH a uniquely good value to our customers and earned
us the reputation for consistent quality.
At DAV-TECH no project is too complex. Our years of experience provide you,
our customer, with new, economical design and application approaches to previously
We also recognize
that good value is the combination of both the cost and quality of the finished
component. The quality issue at DAV-TECH is a systematic effort involving
all levels of the administrative and processing functions. The procedures
followed at DAV-TECH assure quality of the finished product, quality of the
service and cost efficiencies far ahead of our competition.
We take great
pride in our work and want to prove to you that quality, prompt delivery,
application assistance and service are STATEMENTS OF FACT.
term electroless nickel plating refers to that process whereby a dense coating
of nickel-phosphorus alloy is uniformly deposited on a metallic substrate
without the use of electricity. The primary advantage of this process is its
perfect "throwing" power.
Unlike electrolytically deposited coatings ,deposits can be made on any surface
to which the solution has free access. In addition, the electroless coating
is extremely uniform and will not generate excessive buildup on corners or
is an electrolytic process that produces a relatively inert coating on a metallic
surface. When aluminum alloys are anodized, this coating is an aluminum oxide
layer that is generated when the part is made anodic in the presence of a
controlled electrolyte. It is the stability of the aluminum oxide that accounts
for all of the protective properties of the coating.
IN ANODIC COATINGS ON ALUMINUM AND ALUMINUM ALLOYS:
At Dav-Tech Plating we offer two types of anodizing on aluminum. Each type
produces a product with its own specific performance qualities.
The first type is produced in a sulfuric acid bath, and is therefore referred
to as sulfuric acid anodize. This coating is usually transparent with a thickness
range of .0001"-.001".
and aluminum alloys are immersed in a controlled chromic acid bath with additives,
a chemical conversion reaction takes place at the surface of the metal. This
reaction produces a complex , non-crystalline, non-porous coating consisting
of a thin aluminum oxide film with entrapped chromates and dichromates. The
corrosion resistant properties of the coating are primarily due to the chromates,
specifically the hexavalent chromium.
chemical activators are used to enhance the formation of the coating. Depending
upon the desired performance characteristics of the chromate film, the chromating
bath is often modified by changing these activators.
also called hard anodizing, is very similar to sulfuric acid anodizing in
that it is a coating of aluminum oxide that is produced on the surface of
an aluminum component in the presence of a sulfuric acid electrolyte. Compared
to sulfuric acid anodizing, a hardcoating bath is usually run at lower temperatures,
higher amperages, and higher voltages. The resultant coating is far superior
to sulfuric acid or chromic acid anodizing in terms of wear and corrosion
resistance. These properties can be enhanced by the use of sealants. Dav-Tech
hardcoating can be processed to meet the challenges of specific wear and corrosion
