When talking about electroplating, shiny metal finishes come to mind first. As a surface treatment technology based on electrolysis, electroplating is widely used in automotive, electronics, hardware, military and other industries to protect and beautify workpieces.

What is Electroplating? Industrial Protection & Finishing Process
Electroplating deposits a thin metal or non-metal layer on conductive substrates via electrolysis. Common plating types include chrome, nickel, copper and zinc plating. Its core functions are corrosion resistance and decorative finish. It also improves surface hardness and wear resistance to extend service life. Automotive chrome trims, electronic connectors and bathroom hardware all require electroplating.
Production lines can be categorized as manual, barrel, vertical rack and horizontal continuous plating lines. By automation level: manual, semi-automatic and fully automatic lines. By substrate: metal plating, plastic plating and anodizing.
A complete metal plating process includes wax & oil removal, electrolytic degreasing, multistage pickling & activation, multi-layer plating, passivation, rinsing and drying. Each step directly affects the yield rate.

From workpiece pretreatment to finished product — every step matters
Often Overlooked: Fluid Equipment Impacts Plating Yield
Bath cleanliness and circulation stability are critical for plating quality. Fluid transfer and filtration equipment, though auxiliary, play a decisive role.
Equipment selection varies by plating process:
Integrated filter with acid & alkali resistant pump
Low-power dedicated pumps
Dual-tower filter
Vertical pumps
Impurities, bubbles and uneven concentration in plating solution cause pinholes, pitting, color difference and peeling. Stable filtration & circulation continuously purifies the bath for uniform, bright coatings.

Wide Customer Base, Customized Equipment Selection
Electroplating serves consumer goods, auto parts, military components, machinery hardware and electronic components. Requirements for corrosion resistance, flow rate and filtration precision differ greatly across applications. Pump and filter solutions should be customized according to line type and bath chemistry.
From tiny fasteners to precision electronic parts, thin coatings reflect high industrial standards. Premium electroplating depends not only on mature chemical formulas, but also on stable fluid transfer & filtration systems to maintain consistent production and coating quality.
