Chemical Etched Metal Meshes with Tight Tolerance & Diverse Customization for

Metal Mesh Overview
Metal Mesh, also known as precision etched mesh, is a high-performance component manufactured through advanced chemical etching technology. It is characterized by its extremely fine and uniform apertures, smooth burr-free edges, and exceptional structural integrity without altering the material's inherent properties. At Xinhaisen, we specialize in producing custom Metal Mesh with complex patterns and tight tolerances for demanding applications across various high-tech industries.

Manufacturing Process
Our Metal Mesh is produced using state-of-the-art photochemical etching (also known as chemical milling or metal etching). The process involves:

• Cleaning & Preparation: The selected metal sheet undergoes thorough cleaning.

• Photoresist Lamination: A light-sensitive photoresist film is evenly applied.

• Exposure & Development: The desired mesh pattern is transferred from a digital tool to the resist using UV exposure, then developed.

• Precision Etching: The exposed metal areas are precisely dissolved using controlled chemical reagents, forming the mesh structure.

• Stripping & Finishing: The remaining resist is removed, followed by meticulous cleaning, inspection, and any required secondary processing (e.g., plating, annealing).

Metal Mesh Features

• Ultra-High Precision: Capable of producing micro apertures as small as 0.03mm and fine line widths down to 0.015mm.

• Burr-Free & Stress-Free: The etching process creates smooth edges without mechanical burrs, induces no internal stress, and prevents delamination.

• Material Versatility: Processes a wide range of metals including stainless steel, copper, brass, aluminum, nickel, titanium, and their alloys.

• Complex Design Freedom: Effortlessly achieves complex mesh patterns, tapered holes, and varying aperture densities without costly tooling changes.

• Excellent Uniformity: Consistent aperture size and distribution across the entire mesh surface, with uniformity typically within ±0.03mm.

• No Material Hardness Alteration: Maintains the original temper and hardness of the base material.

FAQ
Q1: What is the main advantage of etched Metal Mesh over woven or laser-cut mesh?
A: Etched mesh offers burr-free edges, no mechanical stress or deformation, superior design flexibility for complex patterns, and exceptional uniformity without wire breaks or joint weak points common in woven mesh.

Q2: Can you achieve different aperture shapes and patterns?
A: Absolutely. Photochemical etching allows for virtually any 2D shape—round, square, hexagonal, slot, or custom complex patterns—all in a single process step without additional cost for complexity.

Q3: What is your standard lead time?
A: Lead time depends on order quantity and complexity. Prototypes can often be delivered within 1-2 weeks, while production volumes are scheduled based on specific project needs. We excel at accommodating urgent requests.

Q4: Do you provide material selection guidance?
A: Yes. Our engineering team can recommend the most suitable metal alloy based on your application's requirements for corrosion resistance, conductivity, strength, magnetic properties, or cost.

Q5: How do you ensure quality consistency in large-volume orders?
A: We implement strict process control (SPC), utilize automated etching lines for uniformity, and conduct 100% visual inspection and periodic dimensional checks using optical measurement systems against customer-approved drawings.
