Abstract
A vibratory plating apparatus having a plating liquid in a plating container, a base on which the container is mounted for vibrating movement, and a lid for the top of the container. The bottom of the container has an arcuate bottom. A vibration motor vibrates the container and electrodes are disposed within the container. With this plating apparatus, workpieces can be plated uniformly in a very short period of time at a high current density and with a small amount of plating liquid. Moreover, it eliminates troublesome steps of manually suspending and removing workpieces from hangers.
Claims8
An apparatus for plating workpieces in a plating container, which comprises:
- a base;
- a vibratory plating container means resiliently mounted on said base for vibratory movement, said container means having a lid covering the top and having a bottom with a concavely arcuate cross-section;
- a vibration-generating motor connected with said container means for causing vibration of said container means;
- for causing workpieces in said container means to roll and to be transferred in a direction along said container means parallel to said bottom;
- and
- electrodes of opposite polarities disposed within said container means;
- said container means having a discharge port on one side of the arcuate bottom for discharging a mixture of plated workpieces and plating liquid;
- a screening means below and separate from said container means for receiving said mixture from said discharge port and separating workpieces from the plating liquid;
- and
- liquid return means connected between said container means and said screening means for returning plating liquid to said container means.
