chemical etching

for precise, burr-free, stress-free components

Chemical etching (also known as photo-chemical machining (PCM) and chemical milling) is as precise as it is quick and economical. Complicated, multi-level, multi-feature, high precision parts can be produced without the need for expensive tooling or machinery.

Rapid prototypes can be produced from your drawings in a matter of days, with production then quickly scaled to industrial levels.

chemical etching process



we deal with thicknesses of 25 µm to 2mm. Generally 10% of material thickness with a minimum tolerance of 12μm possible. Feature size and tolerance are subject to:
metal type
sheet size
metal thickness
nature of pattern to be etched


if the metal you require is not listed here, just get in touch. We would be happy to discuss your specification
range of austenitic, ferritic and martensitic stainless steels
mild steel, carbon steel, tool steel, spring steel
aluminium, including aircraft /aerospace grades
brass, phosphor bronze, beryllium copper, nickel silver
nickel alloys: Inconels, mu-metal, alloy 42 (Nilo 42), Invar, Kovar
copper: Including C110 and C101
