TLDR
In this article, the authors proposed a scheme for the protection of plating operations from chemical action in a plating operation by combining the AFOREMENTIONED APPARATUS with a COMPOSITION COMPRISING (1) a POLYMERIC MATERIAL INSOLUBLE in both WATER and PLATING SOLUTIONS and (2) ANTIMONY OXIDE.Abstract:
PROTECTION OF PLATING JIGS, BASKETS, PLATING RACKS, CONVEYOR HOOKS AND THE LIKE FROM CHEMICAL ACTION IN A PLATING OPERATION IS ACCOMPLISHED BY COATING THE AFOREMENTIONED APPARATUS WITH A COMPOSITION COMPRISING (1) A POLYMERIC MATERIAL INSOLUBLE IN BOTH WATER AND PLATING SOLUTIONS AND (2) ANTIMONY OXIDE. THIS IS A CONTINUATION OF APPLICATION S.N. 880,993, NOW ABANDONED, FILED NOV. 28, 1969.read more

Coated plating rack
TL;DR: In this article, a rack for supporting electrically nonconductive articles during the successive chemical or electroless plating and electroplating of such articles has its metal frame covered with a plastic resin coating in which there is dispersed one or more organosulphur compounds so that plating material will not adhere to the rack during the chemical or electrophoresis of the articles supported by the rack, nor during subsequent further electrophasing of the same articles.

Common rack for electroplating and PVD coating operations
TL;DR: Disclosed is a multi-step process for the coating of a substrate without re-racking the substrate between the coating operations comprising: providing a substrate holder with an inert protective polymeric coating covering a substantial portion of the holder; affixing a substrate to the substrate holder; electroplating a coating onto the substrate; applying a physical vapor deposition coating to the coated substrate; and removing the twice-coated substrate from the holder as discussed by the authors.

Density control for electroplatable polymer compositions
TL;DR: In this article, a plastic composition especially suitable for use in barrel electroplating processes is prepared by incorporating in the plastic a siliceous filler and a heavy filler such as barium sulfate or zinc oxide in amounts such that the density of the molded composition is greater than the density in the plating bath.
