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.

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.

01

Raw Metal Sheet Incoming & Storage

Verify alloy composition, thickness, and surface quality; store qualified materials in climate-controlled warehouses with batch traceability.

02

Cleaning & Degreasing

Remove surface contaminants using alkaline ultrasonic cleaning; confirm cleanliness via surface tension test (<35 dynes/cm).

03

Exposure & Plate Making

Transfer design patterns via photolithography: apply photosensitive film → align mask with CCD positioning → UV exposure → develop unexposed areas.

04

Chemical Etching

Dissolve unprotected metal with temperature-controlled FeCl₃/CuCl₂ solutions; monitor depth in real-time (tolerance ±0.005 mm).

05

Surface Treatment

Enhance performance through solvent degreasing, abrasive blasting (Ra 1.6–3.2 μm), phosphating, and passivation.

06

Precision Dimensional Inspection

Inspect critical dimensions using CMM (±0.002 mm accuracy) and vision measuring system; generate SPC analysis reports.

07

Flatness Testing

Measure flatness with laser tester (≤0.1 mm/100 mm deviation); conduct stress relief annealing for out-of-tolerance parts.

08

Full Inspection & Packaging

Perform visual inspection and functional testing; package with anti-static film and desiccant; label with traceability information.

09

Export Shipping

Prepare export documentation; comply with destination country packaging regulations; provide tracking information for sea/air freight.
