Machines for high-precision metals production processes

Photo Chemical Machining Process
Equipment required for precision metal processing

Precision Metal Etching Process: The Precision Metal Etching Process is a sophisticated manufacturing method used to selectively remove metal from thin sheets or foils with high accuracy, creating intricate and precise patterns.

  • Photoresist Application Machine:
    • Purpose: Applies a uniform layer of photoresist onto metal sheets for protection and pattern transfer.
    • Detailed Workflow:
      • Load clean, flat metal sheets or foils onto the machine’s conveyor system.
      • A precision dispensing system applies a uniform layer of photoresist onto the metal surface.
      • The coated metal sheets are transported through a drying mechanism to ensure even and complete drying.
  • Photomask Alignment System:
    • Purpose: Ensures accurate alignment of photomasks with metal sheets for precise pattern transfer.
    • Detailed Workflow:
      • Metal sheets with photoresist are aligned with photomasks using precision optical or mechanical alignment systems.
      • The alignment system ensures that the photomask is accurately positioned over the metal sheet to transfer the desired pattern during exposure.
  • UV Exposure Unit:
    • Purpose: Exposes the photoresist to UV light, hardening it and protecting it from etching.
    • Detailed Workflow:
      • The aligned metal sheets and photomasks are exposed to UV light in a controlled environment.
      • The UV light hardens the photoresist in areas not covered by the photomask, effectively creating a protective mask on the metal surface.
  • Chemical Etching Machine:
    • Purpose: Selectively removes metal from exposed areas of the metal sheets to create the desired pattern.
    • Detailed Workflow:
      • Metal sheets with hardened photoresist are immersed in a chemical etchant bath.
      • The etchant reacts with and dissolves the unprotected metal, leaving behind the desired pattern.
      • The etchant bath’s temperature, concentration, and agitation are carefully controlled for precise etching.
      • The etching process is closely monitored to achieve the desired depth and precision.
  • Rinsing and Drying Station:
    • Purpose: Removes residual etchant and ensures clean, dry metal components.
    • Detailed Workflow:
      • After etching, metal sheets are carefully removed from the etchant bath.
      • The sheets are rinsed in clean water to remove any remaining etchant.
      • A drying mechanism, such as hot air or infrared heating, thoroughly dries the metal sheets.
  • Quality Inspection Equipment:
    • Purpose: Verifies the accuracy and quality of the etched metal components.
    • Detailed Workflow:
      • Precision measurement tools, optical inspection systems, and quality control checks are employed to ensure that the etched components meet required specifications.
      • Measurements are taken to confirm dimensional accuracy, and optical inspections verify the quality of the etched pattern.
