Custom Layered Metal Mesh Filters with Photo Etching + Diffusion Bonding Technology
UPT’s Custom Metal Mesh Filters
UPT offers custom metal mesh filters with fine patterns or holes created using photo etching technology. Photo etching is a process that uses chemicals to selectively dissolve the surface of metals, allowing the creation of highly precise patterns and fine structures. Filters made using this technology have microscopic holes or patterns that prevent small particles penetration, and enable high-precision filtration. Etched filters are primarily used for the following applications:
- Filtration of liquids and gases
- Bypass flow control
- Particle removal in semiconductor manufacturing processes
Due to their precision and high filtration capabilities, etched filters are widely used in industries where strict quality control is required.
Custom Layered Metal Mesh Filters with Photo Etching + Diffusion Bonding Technology
UPT combines photo etching and diffusion bonding technologies to create custom layered metal mesh filters. Filtration performance is significantly enhanced compared with standard filters, and each layer can have different filter characteristics, allowing for step-by-step particle removal. The multi-layer structure increases mechanical strength, and enables high durability even in harsh environments such as high pressure or high temperatures.
Advantages of UPT’s Layered Metal Mesh Filters
High Strength
By stacking layers created with photo etching technology and bonding them with diffusion bonding technology, we achieve both high filtration performance and mechanical strength.
High Maintainability
The flat mesh is resistant to dirt accumulation and can be cleaned, contributing to environmental sustainability through reduced waste and reusability, in line with SDGs goals.
High Design Flexibility
Using photographic development techniques, we can create filters with custom patterns. In addition, diffusion bonding enables the creation of 3D mesh filters with high aspect ratios.
High Flatness
Since no mechanical or thermal stress is applied to the material, no deformation or warping occurs on the processed surface. Burrs, dross, and debris are also avoided, eliminating the need for post-hole processing surface finishing.
