efforts in chroming on plastic (step3)

 Efforts for chrome-plating on plastic (step 3)
After a layer of primer (which helps to smooth the surface of the object and prepare
it for further treatment) and a session in the drying oven, a blast in the spray booth sees
each component treated with up to four layers of a conductive compound. The important word is "conductive".
This allows the chrome-plating process (which relies on electric current to deposit pure metal onto the surface
of the object being chrome-plated or electroplated) to occur once the object is hung in the plating tanks and a jolt
of current sent through it. That's why thick copper wire is used- to deliver the heavy current from the transformer to the object.
