mlcc ceramic capacitor film slitting solution

In the field of electronic components, sinocera, a company specializing in the production of MLCC ceramic capacitors, faces severe challenges in the diaphragm slitting process as the market demand for high-quality MLCCs increases. When the original slitting tool is processing ultra-thin and high-toughness ceramic capacitor diaphragms, problems such as uneven cutting edges, scratches on the film surface, and short tool life frequently occur, resulting in a product yield of only 70%, seriously restricting production capacity.

At this time, Meirente Knife Co Ltd intervened. The R&D team went deep into the sinocera production line to study the microstructure and mechanical properties of the diaphragm material. After many tests, they customized an ultra-precision tungsten steel MLCC capacitor ceramic cutting knife. The unique edge grinding process ensures sharpness, and the special coating enhances wear resistance and lubricity.

After trial by China Ceramics New Materials Company, the effect was remarkable. The trimming accuracy is controlled within ±0.005mm, scratches on the film surface are almost eliminated, the tool replacement cycle is extended three times, the product yield rate soars to 95%, and the monthly output increases from 5 million pieces to 8 million pieces, successfully seizing the market opportunity. The two parties have also launched long-term and stable cooperation to jointly promote the development of the MLCC industry.
