A metal plating apparatus for plating metal with zinc is provided with a rotating device and a plurality of stirring devices. The rotating device has a driving assembly and a rotating assembly. The driving assembly has a driving gear. The rotating assembly is connected with and controlled by the driving assembly. The rotating assembly has a sustaining pillar. A rotating seat is mounted on the sustaining pillar and engaged with the driving gear. The stirring devices is mounted on the rotating seat radially and spaced from each other. The metal plating apparatus improves productivity through an automatic process which shifts locations of the stirring devices by the rotating device and plates metal with a cooperation of peripheral supporting apparatus, and improves working efficiency through decreasing occupied space and the number of operating personnel.

Provided herein are systems, methods and apparatuses for a battery powered electroplating barrel and methods of use.

A method for subjecting garment accessories to a surface electrolytic treatment provides various metallic colors to metallic garment accessories in a cost effective manner. The method can provide a first metallic color on one side of outer surface of the garment accessory and provide a second metallic color on the other side of the outer surface, by placing one or more metallic garment accessories in an electrolytic solution in a non-contact state with an anode and a cathode for passing electric current through the electrolytic solution, passing electric current through the electrolytic solution and generating a bipolar phenomenon on the garment accessory.

Provided are a silver article formed using pure silver, which has high Vickers hardness and prohibits the occurrence of metal corrosion and the occurrence of discoloration; and its method. Disclosed are a silver article and its method, wherein the Vickers hardness is adjusted to 60 HV or higher, and when the height of the peak of 2θ=38°±0.2° by an XRD is designated as h1, and that of 2θ=44°±0.4° is designated as h2, h2/h1 is adjusted to 0.2 or greater.

A container such as a barrel or drum is provided for processing of solid material or parts with a liquid. The container is designed with grooves leading to holes or slots in the side that draw liquid into the container due to the rotation of the container when it is immersed in a tank of liquid. The holes or slots have a small dimension in the direction of rotation to minimize the probability of solid material coming out of the container. The fluid flow caused by the rotation serves to increase the rate of solution replacement inside the container as well as to keep the solid material from falling out through the holes or slots. The container disclosed is useful in processes in the plating, etching, leaching, and surface finishing industries.

A rotational surface treating device with a high treatment efficiency that allows a treatment liquid to be discharged in a short time is provided. When a treatment bath 2 is rotated, parts 20 contact an electrode 50 to be electroplated. In this event, a plating liquid 16 is used as circulated by a pump P. The plating liquid 16 is discharged to the outside through a gap in a side wall 80 for replacement of the plating liquid 16 or the like. During discharge, the plating liquid 16 is not circulated by the pump P. The gap 8 which is formed in the side wall 80 is formed to be smaller than the minimum dimension of the parts 20 on the inner side. The gap 8 is formed to be wider toward the outer side. Thus, water is discharged immediately.

A plating apparatus includes a plating tank and a plating unit that performs electrolytic plating on an object. The plating unit includes a workpiece passage region including a partition wall that allows passage of the plating solution but does not allow passage of the object, the workpiece passage region passing the object from above toward below, an injection unit that injects the plating solution from below toward above, a mixing unit that mixes the plating solution injected by the injection unit and the object to be plated passing through the workpiece passage region, an anode outside the workpiece passage region, a cathode inside the workpiece passage region including a hollow region through which a mixed fluid of the plating solution and the object to be plated passes from below toward above, and a guidance unit that guides the mixed fluid to the workpiece passage region.
