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

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.
