Constant Current Density Anodization

Constant Current Density Anodization

Today, the modern anodizer is faced with challenges never before considered. Many advances technologies have pushed many of the anodizers into the “high-tech” world. Some of the advances, properly implemented, can save the anodizer a lot of time and money. The very important revolution in anodize oxidation industry is to apply constant current density in anodizing.

Items Constant Voltage Constant Current Density
Theory Control the car by accelerator pedal Control the car by cruise control
Oxide Thicknass Tolerance Big Small
Oxide Film Hall Big Small
Oxidize Time Long Short
Seal Stability Not so good Extremely Good
Dye Stability Not so good Extremely Good

Do you want to get
Smaller oxide Thickness Tolerance
Smaller Oxide Film Hole
Shorter Oxidize Time
Better Seal Stability & Dye Stability ?
This is not a dream!
Applying PAS II~III to get scientific method and more reliable anodize oxidizing result!




A variety of precise barrels with diameter of perforation as small as 1mm are available. With our specially designed barrel cylinder and barrel cover, a work of 0.2mm in thickness won’t be stuck into seam between the barrel cylinder and the barrel cover. This feature allows our barrel plating equipment used in plating precision electronic components. Additionally, higher plating efficiency, better quality and shorter plating time can be achieved with 40% of perforation rate.

In addition our sanitary ware plating equipment has cooperated with worldwide big sanitary group for new product and advanced products development, producing for a long time. We are well experienced in Copper and Zinc products.




Reel-to-reel plating is suitable for plating parts come in strips such as terminals and lead frames. The system consists of loading buffer, plating and reeling stages. For semiconductor application, a high pressure desmear unit that removes plastic grounds may be well fitted.

Hard chrome plating provides excellent abrasion, wear and corrosion properties, and it is able to yield great hardiness value. These characteristics are applicable for critical engineering applications, including machine tool cutting surfaces, cylinder bores, strut rods, crankshafts, hydraulic shafts and pistons.



Nickel plating

Nickel-chrome plating is the most common decorative and functional metal plating technique in which a thin layer of chrome is plated over a layer or multiple layers of nickel plating. Due to its excellent corrosion and wear resistances, nickel chrome plating is widely used in automotive parts, tools, and kitchen utensils.




Electroless nickel immersion gold (ENIG) is a type of surface plating that consists of an electroless nickel plating covered with a thin layer of immersion gold which prevents the nickel layer from oxidation. Its excellent surface planarity makes ENIG ideal for fine pitch surface mount technology (SMT).

Electroless Sn, Ni/Pb/Au Plating can be customised for plating metal or PCB in accordance with customers’ requirements. Our equipment ensures stable quality and prolongs replenishing interval of electroless nickel solution.
