Frequently Asked Questions
you just dip it in the Zinc and...?
A: Electroplating is a complicated
multiple step process that must be performed under very
strict controls of each step. The actual depositing of the
plating is a complex electrochemical reaction that occurs
using dissolved metals in an electrolyte solution being charged
with large quantities of electricity.
is better, Zinc or Cadmium?
A: Cadmium is much more
resistant to the ravages of corrosion.
Zinc is more economical and suits most end users needs. Cadmium
is still requested when the part will be used in a harsh environment
such as marine and aerospace applications.
type of parts can BPS process?
A: We are specialists
in volume barrel plating. All of the parts we process
must be put in one of our plastic perforated barrels. The
barrel is then moved through our liquid processing tanks by
computer controlled hoists. These barrels rotate slowly in
each tank in the sequence. Large parts (larger than your forearm)
will not tumble correctly and therefore need to be rack plated.
Q: How fast
can I have my parts plated?
is known for our ability to help when turnaround time is
critical! Rush orders can be returned in 24 hours (with
a small expedite charge).
are all the different colors for and which one is better?
A: Our parts are colored
using a chromating process. Chromates contain chrome metal
that will enhance the corrosion
resistance of any plating. Chrome metal is a dark reddish
brown metal. The rule is usually the darker the color the
more corrosion resistance is added to the plating . The more
chrome the chromate contains the darker the color. In order
of increasing corrosion resistance: White-Blue-Yellow-Black-Olive
is a salt spray test ?
A: 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.
BPS have any hidden charges such
as trucking or environmental surcharges?
A: We at BPS
believe that the price quoted should be the final price. There
have never been any hidden charges and there never will.
