Photo etching (also called photochemical milling) is a chemical manufacturing process that produces accurate metal components. It is completely stress and burr-free. Unlike stamping or laser cutting, the process uses chemicals to selectively remove metal, which means no physical force touches your parts. This preserves the material’s properties while achieving tolerances as tight as ±0.025mm.
Photo etching has several advantages that make it an ideal choice for industries requiring highly precise metal components.
Being a chemical process, photo etching can consistently achieve tight tolerances.
The initial setup is minimal, which makes it economical even for low- to medium-volume production.
There are no tools, dies, or molds required for photo etching.
From soft to hard, photo etching can be used for virtually any metal.
There is no cutting, bending, or hammering in photo etching. Also, there is no force, heat, or pressure applied on metal. Hence, there is no distortion in this process.
Photo etching is the preferred technique for thin and lightweight components used in critical industries such as aerospace.

Here is our streamlined process for transforming raw materials into precise components:
Choose from 100+ metal types in our inventory, cut to the required dimensions
Chemical cleaning removes impurities for optimal photoresist application
UV-sensitive photoresist is applied to both sides using heat and pressure
UV light transfers your design pattern onto the coated metal
The developer solution washes away unexposed areas, revealing component shapes
Metal passes through our automated etching machines with precise speed control
Photoresist is removed, preparing parts for secondary operations if needed
CMM inspection and quality checks ensure parts meet your exact specifications
