Who we are
A source factory for precision chemical etching
Professional chemical etching and custom precision metal parts manufacturer. We provide high-precision metal etching, stamping and OEM customized hardware solutions for electronics, automotive, smart home and industrial equipment industries. Support drawing customization, sample production and mass global supply.
- High Precision Etching TechPhotolithography with CCD mask alignment and real-time depth monitoring holds etch tolerance to ±0.005 mm on critical features.
- Dust-free Workshop ProductionCleanroom exposure and developing lines eliminate particle defects on ultra-thin foils and optical-grade surfaces.
- OEM & ODM Custom ServiceFull drawing-to-delivery service: DFM review, tooling-free prototyping, process optimisation and gradient batch production.
- Strict Dimension InspectionCMM at ±0.002 mm accuracy, vision measuring systems and SPC reporting on every production batch.
Product range
Five families of custom etched hardware
Every part is made to your drawing — the categories below simply show where our processes are most often applied.

Precision parts we manufacture
Real production parts with full specification sheets — material, thickness, tolerance, finish, MOQ and lead time.

Manufacturing process
Nine controlled steps from raw sheet to export
Every stage is parameter-controlled and documented, so the tenth batch measures exactly like the first.
Raw Metal Sheet Incoming & Storage
Verify alloy composition, thickness, and surface quality; store qualified materials in climate-controlled warehouses with batch traceability.
Cleaning & Degreasing
Remove surface contaminants using alkaline ultrasonic cleaning; confirm cleanliness via surface tension test (<35 dynes/cm).
Exposure & Plate Making
Transfer design patterns via photolithography: apply photosensitive film → align mask with CCD positioning → UV exposure → develop unexposed areas.
Chemical Etching
Dissolve unprotected metal with temperature-controlled FeCl₃/CuCl₂ solutions; monitor depth in real-time (tolerance ±0.005 mm).
Surface Treatment
Enhance performance through solvent degreasing, abrasive blasting (Ra 1.6–3.2 μm), phosphating, and passivation.
Precision Dimensional Inspection
Inspect critical dimensions using CMM (±0.002 mm accuracy) and vision measuring system; generate SPC analysis reports.
Flatness Testing
Measure flatness with laser tester (≤0.1 mm/100 mm deviation); conduct stress relief annealing for out-of-tolerance parts.
Full Inspection & Packaging
Perform visual inspection and functional testing; package with anti-static film and desiccant; label with traceability information.
Export Shipping
Prepare export documentation; comply with destination country packaging regulations; provide tracking information for sea/air freight.
