Stainless steel etching

Precision Micro photo etches a wide range of austenitic (300) and martensitic (400) series stainless steel grades from stock. We also machine specialist stainless steel grades, including Sandvik Chromflex strip steels and nickel chrome, and work with customer-supplied steels.

We etch more than two million stainless steel components each month

Prototype to volume — fast

Low set-up costs and rapid lead times make photo etching economical in batch sizes of one-to-multiple millions. As a production steel etching specialist, Precision Micro supplies high-tech companies with more two million steel and stainless steel components each month, many of which are 100% dimensionally inspected, guaranteeing zero defects parts per million (DPPM).

Applications

• Safety-critical springs and flexures used in satellites, ABS braking, biosensors and fuel injection can now flex millions of times because photo etching does not alter fatigue strength, recoil and the flatness of spring steel.
• Medical instruments and biomedical implants photo etched from surgical steels with minimal metallic contamination require zero post-cleaning.
• Complex, corrosion-resistant micro-filters used in showerheads and insect meshes can be manufactured in economical production volumes as photo etching only charges for the first hole.
• Photo etching does not alter the mechanical surface finish of stainless steel and is specified for premium automotive interior trim applications including speaker grilles, tread plates, badges and inlays.
