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…
A pulse power supply is available in single-positive pulse as well as dual positive/negative pulse configurations. It uses a specialized modulation system with fully digital control. The forward pulse width (T+) and reverse pulse width (T−) can be adjusted independently…
Electroplating issues often have a few typical causes. Keeping the current stable with a good electroplating rectifier can help avoid many of these problems. Use the following steps to identify and correct them. Poor Adhesion Check cleaning and activation—oils or oxides can…
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…
Pulse rectifiers don’t just supply DC—they send it in short, controlled bursts. By tweaking the pulse frequency, duty cycle, or waveform, they let you manage processes much more precisely than standard rectifiers. You’ll see them in electroplating, hydrogen electrolysis, anodizing,…
