Etching Metal
Etching is done by removing unnecessary parts through chemical corrosion after an anti-corrosion mask treatment has been applied. This manufacturing process allows TWC to meet precision requirements that cannot be achieved with press punching, allowing us to specialize in products with ultra-thin, ultra-small and complex hole shapes. TWC can supply products for applications such as mic and speaker mesh for smartphones and tablets, mesh filtration filters, and encoder scales.
- Etching metal uses:
Mic/speaker mesh for smartphones/tablets
Mesh filters
Precision springs
Linear encoder scales
Rotary encoder discs - Advantages of etching metal:
• Using a precise photomask to determine the shape pattern makes it possible to perform micron-order complex microfabrications.
• Etching metal makes it possible to achieve a narrow pitch shape that is not possible with press dies.
TWC ensures high-precision machining with no burrs or distortion and no hardening of workpieces.
Because no jigs are used, initial costs can be kept to a minimum.
Regardless of the shape or size of the area being processed, we are able to process products with a short delivery time.
Mass production is also possible by processing multiple pieces at the same time.
Combining etching metal with press processing also makes three-dimensional processing possible. - Etching metal materials:
