Frequently Asked Questions:

What type of plating is best for my parts and my application?

An excellent resource, although it could use an update, is the NASA Fastener Design Manual. It is available for free from:

What type of parts can Delta process?

We are specialists in volume barrel plating. All of your parts are put in one of our plastic perforated barrels. The barrel is then moved through our liquid processing tanks. These barrels are rotated in each tank for uniform coverage. Large parts will not tumble correctly and will need to be rack plated.

How fast can I have my parts plated?

Delta is known for our ability to turnaround orders when time is critical! We will work with you to get them processed as quickly as possible.

Don't you just dip the parts in a big tank?

Electroplating is a process that deposits a thin protective layer (usually metallic) onto a prepared metal surface, using electrochemical processes. The process is controlled with the voltage and amperage, temperature, residence times, and the purity of bath solutions. The steps in an electroplating operation involves pretreatment of parts (cleaning, degreasing, stripping of old plating or paint), plating, rinsing, passivating, and drying. Electroless plating uses similar steps but involves the deposition of metal on a substrate without the use of external electrical energy.

What is a salt spray test ?

A salt spray test is a method to test the relative salt corrosion capabilities of different metal finishing techniques. The plated parts are placed in a closed testing chamber that has a perfect 5% salt solution maintained to a perfect 95 degrees. The salt solution is sprayed or fogged on the parts constantly to accelerate the corrosion rate so the quality of the finish can be measured. Using the salt spray test you can test the effectiveness of chromates as well as the plating itself.

How can I find more details about the specifications ?

Here are a few links that may help: has most specs available will have ASTM specs ditto provides free access to over 20,000 Military, DoD,Federal, NASA, DOE, and Government specifications, standards, handbooks, and publications. Surface Finishing Specifications for Metals.
