Nickel plating

Nickel as coating

Nickel plating is one of the most frequently used procedure for the corrosion protection of metals due to the outstanding corrosion resistance of nickel coating in both alkaline and slightly acidic conditions. The material of the object to be protected is usually steel, zinc casting, copper and its alloys.

Benefits of nickel plating

Types of nickel plating

We use nickel coating for decorative purposes, however, its protective properties are also exceptional. It is also used as a stand-alone coating or an intermediary layer.

The resistance of nickel coating makes it a widely used preference. Highlights are its military and industrial applications. Nickel plating is often used in the electronics industry, while it is also present on the wall sockets in households. Passenger vehicles and telephones also regularly have nickel coating.

Goal of nickel plating

Nickel plating is used for decorative purposes, but its outstanding protective properties should not be forgotten. It is used both as a stand-alone coating and as an intermediate coat. Nickel plating is widely used thanks to its resistance. It has both military and industrial applications. Nickel plating is often used in the electronics industry, and is also found in our own homes in sockets. In addition, nickel plating is also regularly found in cars and telephone handsets.

Our plating tools are designed to be easy to handle and to make the most efficient use of the space available, providing you with a cost-effective solution.

Mass nickel plating

Barrel plating is recommended for small parts (for example screws, and nuts). In case of hanging nickel plating method, the workpiece is not in contact with the electrolyte bath at the point of the attachment and at these points the workpiece does not get the required coating. In addition the barrel nickel plating is more economical, instead of the one by one hanging nickel plating.

Barrel nickel plating

The essence of the process is that the workpieces are placed in a bended plastic immersion bell after an extensive preparation. In the case of barrel plating, we put the bell into the galvanizing bath. The anodes are located along the wall of the galvanization bath while the raw workpieces are in the bell.

Through the axle, the bell rotates at a low speed, and the workpieces have a continuous movement. This method ensures consistent layer thickness. We remove the bell from the electrolyte fluid by a rotating mechanism during unloading and charging. The workpieces remain in the bell while the electrolyte liquid returns to the galvanization bath through the perforation.

By further lifting the bell, workpieces can be take out during rotation. Then we rinse the finished workpieces and centrifuge them with hot air to dry.

We use immersion bells for barrel plating.

Parts suitable for submerged bellows nickel plating are typically fasteners such as washers, nuts. They are based on iron, brass, copper. The diameter of the cylindrical part of the parts to be mass nickel plated is greater than 3 mm. Parts with diameters smaller than this may fall out or get stuck in the slots of the plunger drum.

In the case of submerged-arc nickel-plating, larger parts (such as a 5 cm nut or a 20 cm bolt) can be damaged in the process. Alternatively, parts made of thin and smooth sheet metal can be crushed without any coating on the adhesion surface.

Hanging nickel plating

The maximum size of workpieces for hanging plating are only limited by the dimensions of our 800 mm long, 500 mm high and 250 mm wide baths. We developed our electroplating tools to ensure easy handling and utilise the available space best to offer you a cost efficient solution.
