<Exhibition of Mechanical Element Technology from February 26 to February 28. Makuhari Messe, Hall 3, Booth No. 18-40> In photo-etching processing, metal thin plates are shaped into arbitrary forms through the photo-plate process and the dissolving action of etching solutions. There are no burrs or work hardening like in press processing, and micron-level fine patterns are possible. Etching is suitable for the manufacturing of precision parts. With our unique hybrid etching technology, nickel-clad materials are processed using a fusion of etching and electroforming techniques to achieve high-definition shapes. We also provide one-stop solutions for composite processing (bending, forming, etc.) and surface treatments (high-performance black treatment, etc.). Advantages of etching processing: - High-precision processing without burrs, distortion, burrs, or work hardening - No need for expensive jigs like those used in press processing, significantly reducing initial costs - Capable of manufacturing and shipping in a short lead time, making it ideal for prototypes - Can process multiple items simultaneously, making it suitable for mass production Product examples: shims/apertures/mesh filters (bending processing), optical masks (black treatment processing), scales for encoders (encoder discs = slit disc shapes, linear scale shapes)

**Advantages of Etching Filters and Strainers** - High design flexibility, allowing for intricate shapes. - Unlike wire mesh strainers, there are no overlapping lines, resulting in a flat surface. - No clogging of openings. - Reduced risk of foreign material contamination due to wire breakage. In photo-etching processing, metal thin sheets are shaped into desired forms through a photographic plate-making process combined with the dissolving action of etching solutions. There is no need for expensive molds like in press processing, and there are no burrs or work hardening, allowing for fine patterns at the micron level. ● Photo-Etching Processing Manufacturing of filters and strainer products made from highly corrosion-resistant metals such as stainless steel (SUS). ● Nickel Electroforming Processing In addition to etching, fine-pore filters and strainers with vertical cross-sections are produced through electroforming. Etching + composite processing (bending, diffusion bonding, surface treatment) is also available. Application Fields Electronics and electrical components, automotive parts, medical devices, food industry, etc. At Meltec, we process a wide range of products from metal strainers for the automotive industry to coffee filters for commercial machines.
