Manufacturing Ultra Thin Metal Shims by High Precision Stainless Steel Photo Etching Process

Manufacturing Ultra Thin Metal Shims by High Precision Stainless Steel Photo Etching Process

Xinhaisen, established in 2012, specializes in the widely-adopted technology of stainless steel photochemical etching. This process leverages the potent oxidizing capability of etchants (such as ferric chloride) to precisely dissolve unprotected areas of the metal. The principle involves defining component geometries using a photoresist mask: UV-exposed areas become resistant, while unexposed regions are chemically removed, thus accurately replicating the desired design from the digital artwork. With 13 years of expertise, we deliver both standard full-etching and specialized half-etching for markings or precision bends. For complex requirements, we offer advanced single-side, double-depth etching, unlocking greater design potential for your products.

Advantages of Stainless Steel Photo Etching Metal Shims:

Stainless Steel Photo Etching is an ideal manufacturing method for metal shims, delivering unmatched advantages:

• Exceptional precision and flexibility: effortlessly achieves complex geometries and extremely tight tolerances.
• Complete material integrity: free from mechanical stress, burrs or deformation, ensuring uniform thickness and high-quality surface finish.
• Efficient cost-effectiveness: eliminates the need for expensive hard tooling, supports batch production, enabling rapid delivery and high value for money.

Why use photo etching?

For thin-gauge metal parts (0.02mm - 1.5mm), photo etching presents a superior alternative to stamping, laser, and CNC machining.

• Speed & Agility: Receive prototypes in just days, not weeks, and scale to mass production in days, not months.
• Cost Efficiency: Eliminate high tooling costs — complexity is free, and changes are inexpensive.
• Impeccable Quality: Achieve burr-free, stress-free components with no heat-affected zones, preserving material properties.
• Design Freedom: Process a wide range of metals (stainless steel, copper, titanium, etc.) without compromising temper or magnetism.
