When you have to pick between nickel and chrome plating you need to know that they are not always two options. Sometimes nickel and chrome plating are used together. The decision really depends on what the part’s supposed to do and what…
Anodizing is essentially the industrial supercharging of aluminum’s natural oxidation process. Think of it as forcing the aluminum to grow its own extremely hard, thick, and uniform ceramic skin right from its surface, resulting in what we call anodized aluminum. We…
Q1: Is a precision rectifier really necessary for metal finishing? Only if you care about consistency. Most metal finishing defects—peeling, spotting, uneven color—trace back to power instability. An industrial rectifier eliminates that variable. It’s the difference between guessing and knowing every part…
Metal finishing started as a set of quick fixes on the shop floor. When parts left the lathe they might look fine, but after handling and storage small issues showed up—pinprick stains, slight discoloration, little rough spots. Shops didn’t wait for…
Metal Surface Coating In the metal industry, we often say that the surface decides the lifetime of the part. That’s not an exaggeration. Most metal failures start on the surface — corrosion, friction, heat damage — they all begin there.…
The core function of a pulse power rectifier is to convert alternating current (AC) into controllable pulsed direct current (DC). Its output is not continuous, smooth DC, but rather a pulse waveform with a specific frequency, duty cycle, and amplitude.…
Zinc plating is one of the simplest and most effective ways to stop metal from rusting. Basically, we coat the metal part with a layer of zinc — this zinc acts like a shield, corroding first to protect the metal underneath.…
Nickel plating for industrial parts begins with degreasing and light acid etching to ensure a clean surface. A copper underlayer, typically 5–10 μm, is applied to enhance adhesion. Electrolytic plating deposits nickel to the required thickness, usually 20–40 μm for machinery parts.…
If you’re looking to purchase a 50A ±12 V pulse rectifier for electroplating, here are some solid options and guidance on how to proceed: Liyuan Haina Rectifier Co., Ltd. offers the PNPF-50A/±12V Pulse Plating Rectifier, designed with air cooling, RS-485…
Hard anodizing pushes aluminum to its performance peak through a deep transformation of the surface itself. Components are immersed in a sulfuric acid electrolyte chilled to near-freezing, where controlled electrical currents trigger a reaction that converts the outer layer of aluminum…
