Precision Acid Cleaning Machine
Production-grade precision acid cleaning machine engineered to prepare metal surfaces for downstream etching, coating, plating, or bonding. Combines water washing, micro-etching, ultrasonic cleaning, pickling, and anti-oxidation treatment into one line. Integrated spray and immersion stages, recipe-driven acid concentration control, and acid-resistant wetted parts (PTFE / PVDF / titanium alloy) make it the standard pre-treatment cell ahead of any precision wet etching or surface-finishing process.
Why This Equipment
- Replaces three or four standalone cleaning stations — water wash, micro-etch, ultrasonic, pickle, and anti-oxidation in one integrated line.
- Uniform acid distribution — advanced spray and immersion design eliminates the “edge clean, center dirty” failure mode of manual cleaning tanks.
- Recipe-driven repeatability — different metals and different downstream processes each get a dedicated recipe stored on the HMI.
- Targeted oxide / contaminant removal without damaging the substrate underneath.
- Acid-resistant wetted parts (PTFE / PVDF / titanium alloy) handle HF, mixed-acid pickle, and high-temp baths without leakage.

What Each Cleaning Stage Does
- Water washing — physical removal of loose particulates and water-soluble residues from prior process steps.
- Micro-etching — controlled, very shallow chemical removal that exposes a fresh, reactive metal surface for the downstream process to bond to.
- Ultrasonic cleaning — cavitation-driven removal of stubborn organics, films, and particulates trapped in microscale features.
- Pickling — acid attack on metal oxides, scale, and weld discoloration that physical methods cannot reach.
- Anti-oxidation treatment — terminal passivation to prevent the freshly cleaned surface from re-oxidizing before the next process step.

Frequently Asked Questions
Where are these machines manufactured?
Equipment is manufactured by Xinxin Precision, who is also a working metal etching factory — meaning every chemistry and process shipped has been validated on our own production line first.
Are CE / UL / SEMI compliance packages available?
Yes. Compliance packages are available as engineering options. Specify at order time so wetted parts, electrical, and emergency-stop circuits are sized accordingly.
What is the typical footprint?
Footprint ranges from a single-bench all-in-one unit up to 12 – 25 m floor length for a full production line. Layout drawings are part of the proposal package.
What materials can this machine handle?
This machine is engineered for the material coverage cited in the specification table above. Bath chemistry and wetted parts are selected at build time to match the customer’s actual metal and process mix.
