FAQ's

A zinc plating rack is a specialized rack or fixture used to hold and suspend metal parts during the zinc plating process. It ensures uniform coating and efficient plating of multiple parts simultaneously.

While zinc plating itself is not considered environmentally friendly due to the use of chemicals, some modern processes adhere to stricter regulations and use more eco-friendly practices, such as trivalent passivation.

Zinc plating racks help prevent parts from touching each other during plating, ensuring proper coating distribution and preventing the formation of bare spots.

Zinc plating is widely used in automotive, aerospace, electronics, construction, and various other industries where corrosion protection is vital.

The lifespan of zinc plating depends on the thickness of the coating, environmental conditions, and proper maintenance. In general, it can provide corrosion protection for several years.

The Salt Spray Test (SST) life of Alkaline Zinc plating typically ranges from 200 to 600 hours before the appearance of white rust, and up to 800 hours before red rust forms. The exact duration can vary based on factors such as the thickness of the zinc plating and the specific chromate passivation used

When it comes to zinc plating, the two common methods are rack plating and barrel plating.

Rack plating involves affixing parts to metal racks using screws, wires, or spring fingers, making it ideal for delicate parts that might get damaged by tumbling. This method ensures a high-quality finish and efficiently plates complex shapes and contours, though it is more labor-intensive and requires custom racks, which can increase costs.

On the other hand, barrel plating places parts inside a rotating barrel filled with an electrolytic solution, where the rotation causes the parts to tumble, resulting in an even coating. This method is cost-effective for high-volume plating of small, durable parts and requires less labor and equipment investment.
