Product description:

A 25 micron slit refers to a high-precision machined feature, specifically an extremely narrow gap or aperture cut into a material (typically metal shim or foil stock) with a consistent width of precisely 25 micrometers (0.025 mm). This dimension is about one-quarter the diameter of a human hair, placing it at the forefront of manufacturing precision. The term defines not just a physical attribute but also signifies the manufacturer's exceptional capability in micron-level precision engineering. Achieving such a toleranced feature demands unparalleled expertise in processes, equipment stability, and quality control. These slits are critical components in industries requiring utmost accuracy, such as precision filtration, optical sensors, medical devices, and high-accuracy screening applications.

Product usage:

Mainly used in physical test, spectrum analyzer, electronic equipment, testing equipment.

 Processing method:

The main processing methods are divided into three types: linear cutting, laser processing and etching processing.

Our strengths

1. Up to 2025, we are working in the field of etching for more than 20 years and in 2015 the company spent in nantong new industrial park, draw lessons from the successful experience of shenzhen and kunshan branch, is committed to high-end market in 25 micron slit products of technological innovation, research and development, production and sales. Aspires to be etched industry one hundred enterprises in China!

2. The paramount advantage of a 25-micron slit is its unmatched precision and exceptional batch-to-batch consistency. ZOLID leverages advanced cutting technologies (like high-precision laser systems or sophisticated chemical etching) and rigorous tolerance control (achieving ±2μm) to ensure every single slit maintains an exact width of 25 microns. This extreme uniformity is critical for high-end applications; for instance, in precision analytical instruments, it directly dictates the accuracy and reliability of test results—even a minute deviation can cause significant performance failure. ZOLID's comprehensive SPC (Statistical Process Control) system and fully automated optical inspection equipment monitor key parameters 100% in-process. This guarantees that every delivered product meets specifications perfectly, providing customers with impeccable quality assurance and significantly reducing their production risks and quality concerns.

3. ZOLID's 25-micron slits are not only precise but also exhibit superior physical properties and long-term durability. We meticulously select high-quality materials, such as stainless steels and special alloys, ensuring our slit components offer excellent corrosion resistance, high tensile strength, and anti-fatigue characteristics. During processing, our proprietary techniques meticulously control the heat-affected zone, preventing micro-cracks, burrs, and material stress concentration. This preserves the material's original metallurgical structure and mechanical properties. Consequently, our slit products maintain long-term stability even in harsh operating environments (e.g., high temperature, high pressure, or exposure to corrosive chemicals) without performance degradation due to deformation or failure. This provides our clients' end products with an extended service life, enhanced reliability, and reduced maintenance costs and downtime.

4. A defining characteristic of the 25-micron slit is its design flexibility and high degree of customization. It is far more than a simple straight cut; it can be machined into complex patterns per client requirements, such as precise arcs, interlaced grids, custom arrays, or intricate shapes integrated with other precision features.

5. We can make 25 micron slit with thickness of 0.02 MM, and the slit precision can reach +/-2 micron according to the product.
