Case Studies

Zinc Plating alternative to Powder Coating

Overview:

A major automotive supplier had an in-house powder coating operation that it wanted to remove for floor space, but did not have a source for coating its specialized parts. Greystone offered zinc-alloy plating as an alternative to powder coating and engineered special tooling that eliminated hand masking of the parts, resulting in a more repeatable coating process for assembly.

Challenge:

The customer had to find a zinc alloy coating that was compliant with their end customer requirements as well as equivalent to existing powder coating appearance & performance. There was difficult geometry requirements, including blind & threaded holes that needed to be masked from coating, requiring repeatable & effective masking for high volume zinc plating. Additionally, a rust inhibitor was necessary to coat the unplated portions of the part to prevent transit oxidation of bare steel.

Approach:

Typically, powder coating requires the masking of parts, and is achieved through a very labor intensive process of hand applied tapes and plugs. This makes it very susceptible for variation as well as adding high cost. Greystone used the decades of tooling design from its aerospace component plating to engineer special tooling to minimize masking variation and achieve repeatable coating distribution. An additional process for rust prevention was added to our existing process line to provide the necessary protection for uncoated portions of various parts.

Result:

By eliminating significant amounts of manual labor for masking application, Greystone was able to provide a superior coating that met the customer's needs and allowed them to transform their powder coating line floor into more productive space.
