Improve cutting efficiency and durability of paper with high-hardness WC cutters!
In the paper industry, precise cutting of paper is required. If the cutter's sharpness is poor, the edges of the paper can become rough, leading to reduced cutting accuracy and worsening yield. Tungsten carbide (WC), due to its high hardness and wear resistance, enables longer cutter life and stable cutting quality. Indian tungsten carbide WC contributes to the performance improvement of paper cutting tools. 【Application Scenarios】 - Cutting of paper, cardboard, films, etc. - High-speed, high-load cutting operations - Reducing the frequency of cutter replacements 【Benefits of Implementation】 - Extended cutter life - Improved cutting accuracy - Increased productivity - Cost reduction
