Technical notes on electroplating, written for the people who have to specify it. No marketing, just what we have learned over 33 years of running plating lines.
Outdoor, bathroom, and coastal hardware demands the highest corrosion resistance. How heavier nickel, duplex nickel, and copper-nickel-chrome systems get you there.
Chrome plated and still rusting? The problem is rarely the chrome. Here is how to trace corrosion failures back to nickel thickness, pretreatment, passivation, or substrate.
There is no flat per-piece price for plating. Here are the six factors that drive the cost, and how to ask so you get an accurate quote the first time.
Electropolishing is plating in reverse. It dissolves the microscopic peaks on a stainless surface, leaving it brighter, more corrosion resistant, and easier to clean.
Peeling is an adhesion failure, and adhesion is decided during pretreatment. Here are the real causes and what a supplier should be doing about them.
Thicker is not better. Indoor trim, bath hardware, and outdoor parts each need a different thickness. Here is how to choose, and how thickness ties directly to corrosion life.
A failed salt spray result is rarely just 'not thick enough.' Pretreatment, nickel thickness, porosity, passivation, and substrate match all decide corrosion performance.
On a chrome-plated part, the corrosion protection comes from the nickel underneath, not the chrome. Nickel thickness and duplex nickel decide how long a part survives in humidity.
Eco-friendly plating is not one process. It is a set of controls on chemistry, wastewater, and emissions. Here is what it covers and why it matters for your supply chain.
A mirror finish is decided before the part reaches the chrome tank. Substrate polishing sets the ceiling; the nickel undercoat and the chrome layer do the rest.
Thickness drives appearance, wear, and corrosion performance. Here is how decorative and hard chrome differ, and the three ways thickness is actually verified.
Pretreatment, plating, post-treatment, inspection. The four plating methods and when each one is the right choice for your part.
Neutral salt spray testing is the standard way to compare plating suppliers on corrosion resistance. Here is what the number means, what it doesn't mean, and how to write it into a spec.
Racking, pretreatment, plating, passivation, inspection. Why wire mesh is harder to plate than flat parts, and the two variables that decide whether you get a clean deposit or burnt edges.
Appearance, hardness, corrosion resistance, cost, and application, compared side by side. Plus why most decorative parts use both, in a specific order.
Automation on a plating line is not mainly about speed. It is about removing the human variable, which is where batch-to-batch inconsistency comes from.
Five things to check before you place a plating order in China: finish range, verifiable quality, environmental compliance, capacity, and responsiveness.
