Chemical Etching Explained: What It Is, How It Works, and What It’s Used For
Chemical etching is a precision sheet-metal process where a light-sensitive photoresist 'mask' protects the areas you want to keep, and a controlled chemical etchant removes the exposed metal to create the final geometry. It's often the best fit for fine-detail 2D...
Choosing a Chemical Etching (PCM Supplier): Questions to Ask Before You Quote
Choosing a chemical etching / photochemical machining (PCM) supplier is less about finding ‘who can etch’ and more about finding who can repeatably hit your critical features, document quality properly, and support you from prototype through production. This...
