collaborated with an office equipment brand to customize high-strength hardware blades for office paper shredders. Using high-carbon steel material, through precision forging and quenching processes, the blade is high in hardness, sharp and durable, which can easily shred paper, credit cards and other items, with uniform paper shredding and no jamming hidden danger. The knife shaft is precision machined with 45# steel, closely connected with the blade, rotating smoothly, equipped with wear-resistant gaskets to reduce friction loss and extend service life, and the surface is rust-proof, corrosion-resistant and easy to clean. This customized blade helped the partner increase paper shredder sales by 42% and user reputation was significantly improved.
