Filter mesh with square micro holes is an essential component in various industries, providing precision and accuracy in filtration and separation applications. These mesh screens are crafted using advanced manufacturing processes, including photochemical etching, which allows for high precision and flexibility in design.
What’s the Main Raw Materials of High Precision & Thin Metal Shims by Photochemical Etching?
Photochemical etching is a versatile technique used to create high-precision metal shims and components with intricate designs, like those found in filter mesh with square micro holes. The primary raw materials used in this process include:
Copper: Known for its excellent conductivity and malleability.
Brass: A copper-zinc alloy with good durability and resistance to corrosion.
Stainless Steel Series: Including 304 and 316 stainless steel, these materials offer strong corrosion resistance and mechanical strength.
Other Special Metals: Depending on specific requirements, other metals like aluminum, titanium, and nickel can also be used.
What’s the Thickness of the Raw Materials and the Tolerance Can Be Reached by Photochemical Etching?
Photochemical etching allows for high precision and flexibility in creating metal shims and filter mesh. The typical thickness range and tolerance levels that can be achieved with this process are:
Thickness: 0.001 inch to 0.078 inch
Tolerance: +/- 0.001 inch
This precision enables the production of filter meshes with micro holes that meet exact specifications, making them suitable for critical applications in various industries.
What’s the Process for Coating/Plating After Photo Etching?
After the photochemical etching process, metal shims and filter meshes can undergo additional coating or plating to enhance their properties. The common coatings and platings include:
Nickel Plating: Offers enhanced corrosion resistance and durability, with typical thicknesses ranging from 1—10μ.
Tin Plating: Provides solderability and additional corrosion resistance, with a similar thickness range.
Silver (Ag) Plating: Offers excellent conductivity and is commonly used in electronic components. The typical thickness is 1—10μ.
Gold (Au) Plating: Known for its superior corrosion resistance and conductivity, with a typical thickness of 1—10μ.
What Are the Advantages of Producing High Precision & Thin Metal Shims by Photochemical Etching?
Producing high-precision and thin metal shims by photochemical etching has several advantages, especially for creating filter meshes with square micro holes:
Rapid Prototyping: Prototypes can be completed quickly without the need for additional tooling. Typically, 1 to 3 days is sufficient for producing prototypes.
No Scratches and No Burrs: The etching process minimizes physical stress on the material, resulting in smoother edges and no burrs.
Flexible Design Changes: The process allows for easy modifications to designs, offering flexibility for adjustments.
High Precision with Small Tolerance: Photochemical etching provides accurate results with minimal tolerance, ensuring precise component dimensions.
What’s the Lead Time for Samples, and How Many Samples Can Be Provided for the First Time?
When creating filter meshes with square micro holes, sample production and lead time are important factors. Typically, the following applies:
Sample Quantity and Lead Time: Up to 10 sample pieces can be provided for confirmation, with a lead time of about 4 days for common materials. If the raw material is special, additional days may be required to prepare it.
Mass Production Lead Time: For larger-scale production, the lead time is approximately 10 days after all details are confirmed.
