Overview of Barrel Plating Equipment

To plate on highly value-added micro parts, high-precision plating equipment is also essential. We focus on small desktop-sized barrels, and line up various items which meet customers’ requirements such as special processing which reduces samples get caught to drum’s inner side, designated drums to plate on ultra-fine parts, and so on.
Our barrel plating equipment is adopted by a lot of precision parts manufacturer. Parts plated by our barrel equipment may be found in your smartphones, cameras, watches, and other precision electronic devices.

JYN are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.

What is Barrel Plating?

As the name implies, barrel plating is a device/method to plate on tons of plating samples uniformly by putting the samples into “barrel” shaped vessel and rotating it to mix samples. This method is suitable to plate on small and numerous items, and being adopted to plate on chip capacitors, accessories such as earrings, screws, washers, nuts, and so on. Normally barrel consists of frame and mesh to make plating solution and electricity pass through.

What is important for precision plating?

When plating on minute parts, it is said that more accurate plating can be achieved by preparing multiple small barrels and plating in parallel, rather than plating with one large barrel.

Barrel plating equipment can be roughly divided into “horizontal barrels” and “tapered barrels” according to the purpose.
Basically horizontal barrel is used, but for items that are difficult to plate with a horizontal barrel , an tapered barrel may be more effective. For details, please refer to the following technical information.

Difference between horizontal and tapered barrels

Horizontal barrelTapered barrel FeaturesDrum itself is closed with a lid.
Drum attached horizontally.Drum itself is not closed.
Drum attached diagonally. Pros/Suitable for
Samples are mixed well.
Since it has a lid, samples cannot go out
easily. Many samples can be put inside.Since it has opening, Hydrogen gases generated
during plating can go out easily.Suitable for
very small powdery samples. Cons/
Not suitable for
Hydrogen gases generated during plating
tend to stay inside.Mixing of samples is not good as horizontal
barrel. Since it does not have a lid, need
measure against sample leakage.

Horizontal Barrel Lineup

Horizontal barrels are based on the “Mini Barrel” series, and include the “Tenori Barrel” with a drum capacity of 15mL for ultra-fine parts and the “Cradle Barrel” with a semi-rotational motion to reduce sample deformation.


Tapered barrel Lineup

Our tapered barrels lineups are “Shachihoko®” series with a wide variety of replacement drums and adjustable angles, the “Micro Barrel” with a porous drum, and barrels for aluminum plating that are special order.
