If your target finished copper thickness is 1 oz, we'll start with a ½ oz sheet of material. This is ½ oz on each side. Imaging. Because the production panels are completely covered with copper, the excess copper needs to be removed to reveal your design. To do this, a 1:1 size image of your design is photo plotted onto a film.

How a Thickener Works

Mar 17, 2017  How a Thickener Works. Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids. The early methods of thickening employed plain, flat-bottomed tanks into which the pulp was fed until the tank was full. The solids were then allowed to settle ...
