Manufacturing Cosmetics Specialist
Surface treatment and electroplating are the "cosmetic specialists" of manufacturing—iMParting corrosion resistance, wear resistance, decorative and functional surfaces to metal and plastic components.Full Process Scope
From automotive zinc-nickel alloy plating, electronic connector electroless nickel/gold plating, aerospace aluminum hard anodizing, car body electrophoretic coating, to fastener phosphating—every step relies on precise chemical delivery.Three Major Challenges
These processes share three major challenges: extreme corrosion from strong acids and alkalis (H2SO4, HCl, HNO3, NaOH); precise ppm-level replenishment of brighteners and additives; and complex conditions involving high temperatures, solid particles, and entrained bubbles.Category Text
Delivering an elite electroplating gear pump line, JONSN powers surface treatment chemical metering pump skids, Hastelloy plating solution pump units, and anodizing acid circulation pump systems.Six Core Industry Pain Points in Surface Treatment
Plating bath corrosion & anode sludge, electroless plating metal salt wastage, anodizing low-temperature acid contamination, phosphating crevice corrosion, pickling extreme acid attack, and brightener empirical dosing defects — each eroding coating quality, bath chemistry, and long-cycle plant economics.

How does an electroplating gear pump achieve 15%–20% chemical savings during brightener replenishment?
Conventional timed replenishment causes ±20%-30% dosing deviations, wasting costly brighteners (¥80–200/kg) and degrading coating luster. A JONSN electroplating gear pump (MPG series with 40 μL/r displacement) links with plating rectifiers/ammeters to automatically calculate and inject exact brightener volumes based on real-time Ampere-Hour (Ah) consumption. Its low-shear delivery prevents organic molecule degradation, saving 15%–20% on chemicals annually while locking uniform mirror gloss.
What microfluidic features make JONSN a premier surface treatment chemical metering pump for electroless plating?
In electroless nickel and gold plating (chloroauric acid >¥400/g), cavitation in acidic concentrates causes ±5% dosing errors, reducing plating speed by 20%–30%. A JONSN surface treatment chemical metering pump (MPG series) utilizes Mazak 5-axis carved PEEK gears and nanostructural Zirconia ceramic shafts. Paired with online photoelectric sensor feedback, it tracks metal ion decay with deviation <±1%, eliminating metal ion leaching and precious metal wastage.
Why is JONSN Hastelloy plating solution pump technology superior for severe hydrochloric and mixed acid pickling?
Pickling baths use 37% concentrated HCl, 98% sulfuric acid, and HNO3+HF mixed acids that cause pitting and crack ordinary metal pumps within 2–4 months. Every JONSN Hastelloy plating solution pump (MRA series) is CNC-carved from solid Hastelloy C-276 blocks paired with PTFE/FFKM seals rated >200°C. Completely immune to chloride stress corrosion cracking, its hermetic magnetic drive eliminates acid leaks, delivering verified >20,000 hours continuous operation.
How does a JONSN anodizing acid circulation pump maintain continuous operation under -5°C to 5°C sulfuric acid baths?
Hard anodizing operates in 15%–20% sulfuric acid at -5°C to 5°C, where fluid viscosity increases significantly and attacks standard pump metals. A JONSN anodizing acid circulation pump (MRA/MRB series in 316L or Hastelloy C-276) utilizes positive displacement multi-tooth PEEK gears. Flow remains constant despite viscosity shifts, while hermetic magnetic coupling prevents sulfuric acid leaks and zero metal ions dissolve into the bath, ensuring optimal oxide film hardness and transparency.
