Zinc rack plating production line is to hang the goods according to the pendant, rotating or moving in the plating tank from which the plating is obtained. Rack plating is very simple, the plating pieces immediately hang (hook) on a claw type pendant, and then put the plating solution electroplating, the current flow to the plating pieces immediately. Generally used for sky-high price or large objects plating parts, the quality of the same table is better than rolling plating.

Barrel plating, a lot of plating pieces into a small round hole covered with hexagonal barrel type, there is a conductive line and plating a touch is not fixed, barrel turn gradually in the plating solution, power flow and through a small round hole in and out of the barrel plating solution, current indirect to each plating parts, flip to each piece of plating coating symmetry. Generally used as cheap or small plated parts.

The two ways of the target, cost, time, plating quality, actual operation method, current intensity, plating solution too much is different, and the limit of the roller plating is more, such as: stainless steel, acid copper actual effect is weak, plating parts easy to touch or deformation layer plating is good inconvenience. Roll plating suitable, large quantities of small parts manufacturing.
