How do you ensure gold plating durability?

Gold plating durability is engineered, not hoped for. At Hengdian (HD) Jewelry it is locked in across three controlled stages: base metal preparation, plating process control, and post-plating inspection. Here is how each stage protects the finish your customers wear every day.

Stage 1: Base Metal Preparation

A plating layer can only be as smooth as the metal underneath it. Every brass component is polished and degreased before it enters the plating line, because micro-scratches, polishing dust or fingerprint residue on the base metal are the most common root causes of early peeling. Removing them at the source beats covering them with a thicker deposit later.

Stage 2: Controlled 18K Plating

We plate 18K gold over brass to our own house specification of 0.1 to 0.3 micron. To be precise, this is our own standard: a controlled in-house specification rather than an industry-wide figure. Bath chemistry, current density and dwell time are monitored so the deposit lands inside that window batch after batch. If your market or price segment calls for a different deposit, custom plating thickness is available on request.

Stage 3: Durability Checks Before Dispatch

Plated pieces pass adhesion and appearance spot checks on the line, then a second quality control pass at our Guangzhou warehouse before anything ships. Batches that fail are pulled at the warehouse, not discovered by your customers.

Why In-House Control Works

Our Own Factory

Production runs in our own factory in Shanwei Haifeng, Guangdong, with 5 lines under one roof. Nothing critical is outsourced, so plating parameters do not drift.

14 In-House Processes

From modeling to packing, 14 processes are handled internally, which keeps accountability for durability in one pair of hands.

Fast, Repeatable Development

New designs can move from approval to mass production in as fast as 7 days, and the same process controls apply to every new release.

Scale Behind the Standard

With 40,000+ pieces in stock and 500+ new designs monthly, the process has to stay repeatable.

What This Means for Your Order

  • Plating lands inside our house spec on every batch, not just the sample.
  • Two inspection gates: on the production line and again at the Guangzhou warehouse.
  • Custom plating thickness available on request for specific markets.
  • 1V1 service, so a durability question is answered by the team that controls the process.

Quick Answers

Is 0.1-0.3 micron an industry standard?

No. It is our own house specification for 18K gold plating over brass. We state it openly so buyers know what they are comparing against.

Can I request thicker plating?

Yes, custom plating thickness is available on request. For 18K gold plated custom orders the MOQ starts at 120 pieces per design.

Does thicker plating always last longer?

A heavier deposit generally resists wear longer, but lifespan also depends on how a piece is worn - friction, moisture and storage matter too.

Where does final inspection happen?

At our Guangzhou warehouse, where every batch gets a second QC pass before dispatch. See our factory story on the about us page.
