Custom Stainless Steel Filter Disc with Micro Perforation

We can achieve a minimum square aperture of 0.1 mm for chemical etching precision metal mesh and micro perforated metal sheets. For round holes, the minimum diameter depends on material and thickness. Features below 0.1 mm are possible in special cases, but >=0.15 mm is recommended for mass production of precision etched metal parts and filter components. Standard tolerance: 0.05 mm. Ultra-thin or micro etched structures: up to 0.01 mm depending on design and thickness.

Minimum thickness: 0.01 mm (special applications). Mass production range: 0.03-1.0 mm for stable production of precision etched metal parts and thin metal components. Materials include: Stainless steel, copper, aluminum, carbon steel, nickel alloys, and other metals suitable for chemical etching and micro fabrication.

Yes. We provide RoHS compliance declarations and material test reports (MTR/MTC) for chemical etching precision metal parts, precision metal mesh, and etched components. For most standard metal materials, RoHS is generally not required. If needed, we can support it. Usually, we provide material composition reports or material property reports such as chemical composition or performance data. Sample testing is supported before mass production.

Yes. We support full customization for chemical etching precision metal mesh, including: Round holes Square holes Irregular hole shapes / irregular mesh patterns Gradient hole patterns (variable density mesh) Custom geometric patterns based on drawings

Yes, both double-sided etching and half etching (depth-controlled etching) are supported for precision etched metal parts and micro structured components. Recommended stable thickness: >=0.1 mm. Thinner materials require separate evaluation. Key factors include etching depth, groove width, feature pitch, material type, and production stability. If unsure, please send drawings or specifications via online inquiry or email for evaluation.
