Product Overview

Precision Metal Filter Meshes for Critical Filtration Applications

At Xinhaisen, we manufacture high-precision metal filter meshes using advanced photochemical etching technology. Our filter meshes are designed to provide superior durability, uniform aperture distribution, and burr-free surfaces for the most demanding filtration environments. We transform raw metal coils into precision components that meet the exacting standards of industries ranging from medical devices to automotive systems.

What is Photo Chemical Etching?

Photo chemical etching, also known as photo etching or chemical milling, is a precision manufacturing process used to create complex metal components. The process involves several key steps:

• Cleaning: The metal coil is thoroughly cleaned to remove any contaminants.

• Lamination: A photoresist film is applied to both sides of the metal sheet.

• Exposure: A tool with the exact pattern of the filter mesh is used to expose the photoresist to UV light, hardening the desired pattern.

• Development: The unexposed (soft) photoresist is washed away, leaving the metal exposed in the areas that need to be etched (the holes).

• Etching: The metal is passed through an etching chamber where an etchant solution precisely dissolves the exposed metal, creating the filter holes.

• Stripping: The remaining hardened photoresist is removed, revealing the finished, burr-free precision filter mesh.

This process is ideal for filter meshes because it produces absolutely burr-free and stress-free components without altering the material's magnetic or physical properties.

Product Features

Our precision etched filter meshes offer distinct performance advantages over stamped or woven alternatives:

• Exceptional Precision: Achieve micro-hole diameters as small as 0.03mm and line widths down to 0.015mm with high uniformity.

• Burr-Free Surface: The chemical process ensures absolutely no burrs, which prevents particle entrapment and ensures consistent flow.

• Material Versatility: Capable of etching a wide variety of metals including Stainless Steel (304, 316L), Titanium, Copper, Brass, and Nickel alloys.

• Design Flexibility: Easy to create complex hole shapes (round, square, slotted, hexagonal) and custom patterns without expensive hard tooling.

• Material Integrity: The process does not work-harden or stress the metal, preserving its original flatness and magnetic properties.

• Scalability: Equipped with roll-to-roll exposure capabilities, we are capable of handling large volume orders efficiently (up to 1000㎡ daily) with consistent quality.

Frequently Asked Questions

Q1: What is the minimum hole size you can etch?
A: We can etch micro-holes down to 0.03mm (30 microns) in diameter, depending on the material type and thickness.

Q2: Can you handle large volume orders?
A: Yes. We have a strong production capacity with roll-to-roll lines, capable of producing up to 1000 square meters per day to fulfill large, time-sensitive orders.

Q3: Will the filter mesh have burrs or sharp edges?
A: No. One of the main advantages of chemical etching is that it produces completely burr-free and flat components. There are no mechanical stresses or deformations.

Q4: What metals can you etch?
A: We can etch a wide range of metals including Stainless Steel (SUS304, SUS316L), Titanium, Copper, Brass, Beryllium Copper, and other alloys.

Q5: How do you ensure the quality of the meshes?
A: We utilize automated optical inspection and 2D measuring instruments throughout the production process to ensure every mesh meets the specified tolerance of ±0.01mm.
