Chemical Etching of Slit Sheet adopts state-of-the-art photochemical etching technology, a non-contact cold processing method that sets the standard for high-precision slit sheet manufacturing. Unlike traditional mechanical cutting or laser ablation, chemical etching uses selective chemical corrosion to create precise slit structures on high-quality substrates, enabling the production of slit sheets with unmatched precision and performance—critical for applications where slit accuracy, surface quality and operational stability are non-negotiable.

The core advantage of chemical etching in slit sheet processing is its micron-level precision and slit uniformity. Chemical etching achieves exceptional dimensional control, with slit width error strictly controlled within ±0.001mm, spacing deviation less than 0.0008mm, and slit edge straightness above 99.9%. This level of precision is essential for slit sheets, as even minor variations in slit size or spacing can disrupt light transmission, signal stability or measurement accuracy. The etched slit sheets feature perfectly uniform slit profiles, smooth edges and consistent thickness, ensuring optimal performance in optical, electronic and industrial applications.

Furthermore, chemical etching ensures superior surface quality and structural integrity. As a cold processing method, it avoids the thermal damage, burrs and mechanical stress associated with laser ablation or mechanical cutting—defects that can reduce the slit sheet’s service life and compromise performance. Slit sheets are typically made of optical-grade or high-strength substrates (stainless steel, copper, quartz), and chemical etching preserves their intrinsic properties, such as corrosion resistance, thermal conductivity and light transmittance. The non-contact process eliminates surface scratches and microcracks, achieving a burr-free surface that minimizes friction and ensures stable operation in harsh working environments.
