Custom Precision Metal Components Manufacturing with PCM (Photo Chemical Machining)
Photochemical machining (PCM), also known as precision chemical etching, is a manufacturing process used to produce high-precision metal components through controlled chemical dissolution. This method is particularly suitable for applications requiring complex geometries, tight tolerances, and burr-free edge quality. Xinhaisen, a professional manufacturer in PCM, specializes in custom precision metal components.
Compared with conventional processes such as stamping or laser cutting, PCM enables the production of stress-free metal components without introducing mechanical deformation or heat-affected zones. This makes it an ideal solution for industries where dimensional stability and repeatability are critical.
What Is Photochemical Machining (PCM)
Photochemical machining is a subtractive manufacturing process in which metal is selectively removed using chemical etchants. The process does not rely on mechanical cutting forces, ensuring superior precision and quality.
PCM (Photo Chemical Machining) Process
Material Prep: Clean and degrease metal sheets
Photoresist Coating: Apply UV-sensitive resist
Exposure: Transfer flow field design via photomask
Development: Remove unexposed resist to reveal etching areas
Etching: Immerse in etchant to dissolve unprotected metal
Strip & Clean: Remove residual resist and polish
QC Inspection: Validate dimensions, conductivity, and surface finish
Key Capabilities of PCM Metal Manufacturing
PCM is widely used for producing precision components from thin metal sheets with the following capabilities:
Capability
Specifications
Material Thickness Range
0.02 mm to 3.0 mm
Dimensional Tolerance
±0.005 mm to ±0.01 mm
Minimum Feature Size
Line width: 0.01 mm | Hole diameter: φ0.02 mm
Edge Quality
Burr-free edges, no mechanical stress, no thermal distortion
Available Materials for PCM Processing
Photochemical machining is compatible with a wide range of metals, including:
Stainless steel
Copper and copper alloys (including bronze, phosphor bronze)
Nickel and nickel alloys
Aluminum
Titanium
Material selection depends on application requirements such as conductivity, corrosion resistance, and mechanical strength.
Typical Applications of Etched Metal Components
Automotive and EV Systems
Battery connectors
Busbars
Sensor components
Precision shims
These components require stable conductivity and dimensional consistency under vibration and thermal cycling.
Medical Devices
Minimally invasive instrument components
Medical filters and micro meshes
Precision structural parts
Burr-free edges are critical to ensure safety and performance in medical applications.
Electronics and Consumer Devices
EMI shielding components
Lead frames
Connector parts
PCM supports high-density layouts and thin metal structures essential for modern electronics.
Energy and Hydrogen Systems
Bipolar plates
Flow field plates
Heat exchanger components
These applications require uniform channel geometry and controlled depth tolerances for optimal performance.
